quarter under review. As noted previously, the late J. W. 

 Jenkinson has a paper on " The Placenta of a Lemur " {Quart. 

 Jour. Micro. Sci. vol. lxi. pt. 2). A description of the placenta 

 is given, and it is pointed out that its structure conforms to 

 that of other Lemuroids save Tarsius. A valuable contribution 

 has been made to our knowledge of the ductless glands by two 

 papers in Proc. Roy. Soc. B. 610 August. " The Development 

 of the Thymus, Epithelial Bodies, and Thyroid in the Marsu- 

 pialia " consists of two parts : Part I, Trichosurus vulpecula, 

 Frazer and Hill, and Part II, Phascolarctos, Phascolomys, and 

 Perameles by Frazer. They are abstracts of the papers to be 

 published later in the Transactions, and will be best dealt with 

 there. Thomas has three papers in the Annals and Magazine of 

 Natural History, " Notes on the Asciatic Bamboo-Rats (Rhi- 

 zomys, etc.) " and " On Bats of the Genus Promops " (both in 

 July) and " New African Rodents and Insectivores " mostly 

 collected by Dr. C. Christy for the Congo Museum (August). 

 Two further parts of " On the African Shrews belonging to the 

 Genus Crocidura " have been added by Dollman (Part I, Ann. 

 and Mag. Nat. Hist. July ; Part II, ibid. August). Pocock con- 

 tributes papers " On the Species of the Mascarene Viverrid 

 Galidictis, with the Description of a New Genus and a Note on 

 Galidia elegans " (Ann. and Mag. Nat. Hist. August), and " On 

 Some of the External Characters of the Palm-Civet (Hemi gains 

 derby anus) and its Allies " (ibid. September). 



ANTHROPOLOGY. By A. G. Thacker, A.R.C.Sc, Public Museum, 

 Gloucester. 



In the October number of Science Progress I summarised 

 in considerable detail an important paper by Dr. G. E. Pilgrim 

 on Sivapithecus indicus, a remarkable Miocene animal, which 

 Pilgrim believes is a primitive genus of the Hominidae (see 

 Records of the Geological Survey of India, vol. xlv. Pt. I, 191 5). 

 I am now able, with the author's kind permission, to reproduce 

 three of his figures of this fossil. Fig. 1 shows the portion of 

 the right side of the mandible containing the premolar and 

 molar teeth, and fig. 2 shows the fragment of the left side 

 of the mandible, wherein the canine and the symphysis may 

 be seen. Fig. 3 is Pilgrim's restoration of the entire lower 

 jaw, as viewed from above. The figures will repay close 

 examination, for the fossil is one of the half-dozen most impor-
