Calcareous Nodule

We propose in this communication to supplement our previous account of the Dicynodon ( D. leoniceps ? ) skull by some observations on another specimen of unknown species, for which we are indebted, through the kind offices of Dr. Smith Woodward, to the generosity of the Trustees of the British Museum. As is so commonly the case, this skull is included in a hard calcareous nodule, and thus inaccessible to systematic observation except by serial sections. It was found in the Karoo beds of South Africa.

Study of South African populations of chydorid cladocerans in the Alona affinis-group (Anomopoda: Chydoridae) revealed two closely related species, Alona affinis (Leydig, 1860) and a second, previously unknown, species A. martensi sp. n. No significant differences were seen between South African and Eurasian populations of A. affinis sensu stricto. A. martensi sp. n. differs from other species of the affinis-group by a shorter spine on the basal segment of antennal exopodite, and can be distinguished from A. affinis by a number of additional morphological characters. A. affinis is distributed mainly in the East and South regions of the Republic of South Africa, and is less frequented in this region. Confined mainly to artificial water bodies its presence may be human-mediated. A. martensi sp. n. sems to be endemic to the Drakensberg mountains within the borders of the KwaZulu-Natal Province and Lesotho.

Cradle Of Humankind

Homo naledi is a previously-unknown species of extinct hominin discovered within the Dinaledi Chamber of the Rising Star cave system, Cradle of Humankind, South Africa. This species is characterized by body mass and stature similar to small-bodied human populations but a small endocranial volume similar to australopiths. Cranial morphology of H. naledi is unique, but most similar to early Homo species including Homo erectus, Homo habilis or Homo rudolfensis. While primitive, the dentition is generally small and simple in occlusal morphology. H. naledi has humanlike manipulatory adaptations of the hand and wrist. It also exhibits a humanlike foot and lower limb. These humanlike aspects are contrasted in the postcrania with a more primitive or australopith-like trunk, shoulder, pelvis and proximal femur. Representing at least 15 individuals with most skeletal elements repeated multiple times, this is the largest assemblage of a single species of hominins yet discovered in Africa.

The Matrix

Some time since Prof. T. Rupert Jones directed my attention to a curious fossil in the British Museum, obtained by Mr. Bain from Styl Krantz, Sniewe Berg, South Africa. The matrix is of the same nature as that in which the Dicynodonts are so commonly found, and exhibits the greater part of the skeleton, but unfortunately not the skull, of a Lacertilian reptile, not more than seven or eight inches in length. It is represented of the natural size in Plate XI., Fig. 1. The trunk is about two and a half inches long, and appears to have attained hardly more than one-third the length of the tail, which is bent round into three-quarters of a circle, and consists of vertebræ, which are very stout near its root, but become attenuated at its termination (a). The centra of these vertebræ appear to have been slightly constricted in the middle, and are about one-tenth of an inch in length. The anterior caudal vertebræ present strong and long transverse processes. The dorsal vertebræ can hardly have been fewer than eighteen or twenty, and seem also to have possessed hour-glass shaped centre. They are for the most part provided with long curved ribs, the hindermost four or five pair of which become gradually shorter. One of two vertebræ in front of the sacrum may have been devoid of ribs.

Micropholis Stowi was described by Huxley in 1859 from a small and very incompletely preserved skull found by G. W. Stow at Rhenosterberg (north-west of New Bethesda), District Graaf Reinet, Cape Colony. Subsequently R. Owen described another specimen as Petrophryne granulata. In his description he suggested that it might prove to be identical with Huxley's type. The British Museum now contains these two type-specimens and three other examples of the form, all except Huxley's type being from the Procolophon zone of Donnybrook, Upper Zwartkei, District Queenstown.

Mr. Sydney Ryan, of Darkton, Managing Director of the Ryan Tin Mines, situated on the Embabaan River in West Swaziland, has collected and sent to England a large collection of rock-specimens from the Ingwenya Berg, the dominating feature of the district. He has also provided plans and sections of the district, which are here partly reproduced. The specimens have been presented to the Mineralogical Department of the British Museum, together with a complete catalogue, having reference to the Sections referred to above, and indications of the lithological characters of the 140 specimens. Mr. G. Th. Prior, F.G.S., has kindly aided the writer in the critical examination of the rocks, and is communicating a description of those of economic value to the forthcoming number of the Mineralogical Magazine.

Behavioral Information

The cobweb spider genus Anelosimus contains species showing various levels of social behavior. American Anelosimus are well known and several species have been described from Europe, China, Japan, and Madagascar. However, to date, only two behaviorally unknown species have beendescribed from continental Africa, Southeast Asia, and Australasia combined. In this paper we describe seven new Anelosimus species, A. agnar n. sp. (Malaysia), A. biglebowski n. sp. (Tanzania), A. dude n. sp. (Tanzania), A. linda n. sp. (Malaysia), A. monskenyensis n. sp. (Kenya), A. nelsoni n. sp. (South Africa), and A. sulawesi n. sp. (Sulawesi) from Africa and Southeast Asia. We also redescribe A. kohi Yoshida, 1993 and provide evidence for subsocial behavior in that species. Anelosimus kohi shows a marked color polymorphism that is apparently habitat-related, both in populations in Malaysia and in Singapore. Several of the undescribed species were included in previous phylogenetic analyses, and the likely phylogenetic placement of each species is discussed. Based on new behavioral information we discuss the phylogenetic and geographical distribution of temporary and permanent sociality in Anelosimus.

Cape Of Good Hope

Sepedon hæmachates has received other names, such as Naja hæmachates, Naja Capensis , and Aspidelaps hæmachates . It is found at the Cape of Good Hope, Namaqualand, Clanwilliam, and elsewhere in South Africa. It is known to the Dutch as “Rhinghals” and “Spuwslang,” and in Cape Colony also as the “Brown Snake.” It measures about 2 feet in length, and has the reputation of being one of the most lethal of the South African snakes. Being a Colubrine of the sub-family of the Elapinæ, it is therefore closely related, in zoological characters, to the members of the Naja genus which includes the deadly Cobras and Hamadryad. So far as we have been able to ascertain, the action of this venom has not before been examined. The Sepedon venom used in this investigation was extracted from eight dried glands: two of which were sent to one of us, in 1898, by Mr. J. W. van Putten, of van Putten’s Vlei, Clanwilliam, and the other six, in 1901, by Dr. Robertson, of the Agricultural Department of Cape Colony. To these gentlemen we take this opportunity of expressing our great indebtedness. The glands had been removed in South Africa from recently killed serpents, cleared of adhering fat and other extraneous matter, and then thoroughly and quickly dried by being hung up in a warm and airy place. Along with the dried glands, there were sent the heads of several of the serpents from which these glands had been removed. The latter were submitted to Mr. Boulenger, F. R. S., of the British Museum, and he confirmed the identification of their being heads of Sepedon hæmachates .
