unless it were necessary to assign it to a separate family. He proposed for 

 its reception a new genus, Leithia. 



A communication was read from Mr. W. E. J. Bramley describing the 

 mode of capturing Loder's Gazelle, Gazella loderi, adopted by the Arabs of 

 the Western Desert of Egypt. 



Mr. G. A. Boulenger described a new Snake, Typlops nigricauda, and a 

 new Frog, Chiroleptes dahlii, from Northern Australia. A second paper by 

 Mr. Boulenger contained an account of the type-specimen of Boulengerina 

 stormsi — an Elapoid Snake from Lake Tanganyika, recently described by 

 M. Dollo. 



December llth.— Sir W. H. Flower, K.C.B., LL.D., F.R.S., President 

 in the chair. 



Dr. Donaldson Smith offered some remarks on some of the animals 

 observed by him during his recent journey to Lakes Rudolph and Stephanie, 

 and alluded especially to the species of Zebras and Antelopes encountered 

 during his journey. 



Mr. Sclater exhibited and made remarks on the head of an Antelope 

 obtained in Kavirondo, British East Africa, by Mr. E. Gedge. This 

 Antelope had been hitherto identified with the " Kob " of Western Africa, 

 but appeared to belong to a distinct species, to which the name Cobus 

 thomasi had been given by Herr Neumann. 



Mr. G. F. Hampson read a paper on the classification of two subfamilies 

 of the Moths of the family Pyralidce, the Schcenobiince and Crambina : in 

 the former subfamily twenty-five genera were classified, in the latter thirty. 

 Both subfamilies were stated to be parallel developments with the 

 Hydrocampince from the primitive stock of the Pyralidce, represented 

 among living forms by the more generalized Pyraustince andthe Scopariince. 



A communication was read from Mr. Oldfield Thomas on Ccenolestes, a 

 still-existing survivor of the Epanorthidce of Ameghino, and the repre- 

 sentative of a new family of recent Marsupials. The specimen upon which 

 the new genus and species {Ccenolestes obscurus) was based had been 

 received from Bogota. The mammal described by Tomes in 1860 as 

 Hyracodon fuligitiosus, from Ecuador, was a second species of the same 

 genus, and the name Hyracodon being preoccupied, Ccenolestes was proposed 

 in its place. 



Mr. Walter E. Collinge read a paper on the sensory and ampullary 

 canals of Chimcera, and the innervation of the same. After describing the 

 Elasmobranch character of the sensory canals, the author pointed out that, 

 in addition to the ampullary canals described by Leydig, there were two 

 other forms which were now described for the first time. 



Mr. F. A. Bather read a paper on the fossil crinoid Uintacrinus, con- 

 taining a complete morphological description of Uintacrinits socialis, based 

 on specimens from the Upper Cretaceous Beds of Western Kansas, now in
