7th February, 1899. — The Secretary read a report on the additions 

 that had been made to the Society's Menagerie during the month of January 

 1899, and called special attention to a young male example of the Argali 

 Sheep [Ovis amnion) received on deposit on January 18th. — Mr. F.E.Bed- 

 dard, F.R.S., read a paper on the cerebral convolutions of the Gorilla, in 

 ■ which he reviewed our previous knowledge of the subject, and recorded his 

 own observations on five brains of this animal which he had in his possession. 

 — A communication from Dr. R. O. Cunningham, C.M.Z.S., contained 

 a note on the presence of supernumerary bones occupying the place of pre- 

 frontals in the skulls of certain Mammals. These bones had recently been 

 observed by the author in skulls of Macropus giganteus and Phascolomys 

 platyrhinus. — Mr. G. E. H. Barrett-Hamilton, F.Z.S., read a paper on 

 the Mice of St. Kilda, of which he recognized two species — Mus hirtensis^ 

 sp. nov., a representative of M. sylvaticus, and M. muralis, sp. nov., repre- 

 senting M. musculus. Both of these species showed good distinctive charac- 

 ters from their well-known prototypes. — A communication was read from 

 Prof. W. Blaxland Benha m containing a detailed anatomical account of 

 the structure of Notonns, based on the examination of a young female spe- 

 cimen of this bird recently received at the Otago Museum, Dunedin, New Zea- 

 land. — A communication was read from Mr. F. N. Buxton, F.Z.S., con- 

 taining some notes on the herd of Bisons living in the Emperor of Russia's 

 forest of Bielovege in Lithuania, which he had made during a visit to that 

 place in the past autumn. — Mr. G. A, Boulenger, F.R.S., described two 

 new species of Lizards, under the names of Lacerna Jacksoni and Chamaesaura 

 cmnectens, from specimens contained in a collection of Reptiles recently sent 

 to the British Museum by Mr. F. J. Jackson, C.B., from the interior of Bri- 

 tish East Africa. — Mr. Boulenger read the second part of a memoir en- 

 titled "A Revision of the African and Syrian Fishes of the Family CichUdae}'' 

 Owing to the large amount of material contained in collections recently re- 

 ceived from Lake Tanganyika and the Congo, the author had been obliged 

 te make an alteration in the plan of arrangement proposed in Part I. of the 

 paper, and instead of dividing the family into 9 genera, he had found it ne- 

 cessary to recognize 19 genera. The present Part contained a synopsis of 

 all the known African and Syrian genera, an enumeration of all the species, 

 and definitions of the genera Tilajna, Steaiocraniis, Docimodus, and Paretro- 

 plus and their species, several of which were described as new. — P. L. 

 S dater, Secretary.
