{Giraffa camelopardalis), presented by Col. B. Mahon, C.B., D.S.O., and to 

 two iemale Grévy's Zebras [Equus Grevii) deposited by His Majesty the King. 



— Mr. Sciate r exhibited and made remarks upon some photographs of a 

 Persian Ibex [Capra aegagrus) bearing an unusually fine pair of horns, and 

 of the Rocky Mountain Goat [Haplocerus montanus), taken from specimens 

 in the Zoological Garden of Philadelphia. — Dr. A. Günther, F.R.S., 

 exhibited and made remarks upon some living larvae of the Bull-frog of 

 North America, bred in Surrey. — Sir Henry Howorth, K.C.I.E., F.R.S., 

 exhibited and made remarks upon the head of a Fallow Deer which showed 

 a very curious morbid form of growth of the horns. — Mr. R. E. Holding 

 exhibited and made remarks upon the jaw of a Domestic Sheep with an ab- 

 normal number of molar teeth. — A letter was read from the Rev. Francis 

 C. R. Jourdain in which it was pointed out that Mr. J. G. Millais, in his 

 paper on the occurrence of Bechstein's Bat in England (P. Z. S. 1901 [ii.] 

 p. 216), had omitted to state that two specimens of this Bat had been taken 

 in the New Forest in 1886. — Dr. C. W. Andrews, F.Z.S., gave an 

 account, illustrated by lantern-slides, of the palaeontological discoveries 

 made by himself and Mr. H. J. L. Beadnell during their recent visit to the 

 Fayum, Egypt. — A communication was read from Mr. R. Shelford, 

 C.M.Z.S., dealing with the Mimetic Insects and Spiders of Borneo and 

 Singapore. — Mr. C. Tate Regan read a paper on the Classification of the 

 Fishes of the Suborder Plectognathi. Mr. Regan pointed out that to the 

 diagnosis of this Suborder "ribs absent" should be added the so-called ribs 

 of the Balistidae, Triacanthidae (and presumably of the Triodontidae) being 

 epipleurals. Two divisions of the Suborder were recognized — Sclerodermi, 

 comprising the less specialized forms, which were arranged in 4 families: 

 Triacanthidae, Triodontidae, Balistidae, and Ostraciontidae ; and Gymno- 

 dontes, comprising the highly specialized Tetrodontidae, Diodontidae, and 

 Molidae, which agreed in the abnormal structure of their pectoral arch and 

 vertebral column. The Triodontidae -were for the first time removed from 

 the Gymnodontes and placed among the Sclerodermi. Diagnoses of the 

 families and the genera were given. The paper concluded with descriptions 

 of several new species, and with notes, based on specimens in the British 

 Museum Collection. — A communication from Lt.-Col. J. M. Fawcett 

 contained notes on the transformations of the Butterfly Papilio dardanus and 

 the Moth Philampelus megaera, and descriptions of two new species of Moths 

 under the names Rabdosia elio and Dermaleipa daseia. — Mr. Oldfield 

 Thomas read a paper on the Mammals collected by Mr. Edward Degen 

 during his recent expedition to Lake Tsana, Abyssinia. Twenty-five species 

 were enumerated, and the following were described as new: — Herpestes 

 galera milis, distinguished by its small size and small teeth; Lutra capensis 

 Meneliki, like the Cape Otter, but larger, darker, and with white underfur; 



Otomys Degeni, with one deep and one shallow groove in each upper, and 

 two deep grooves in each lower incisor; Arvìcanthis somalicus, a small pale 

 form allied to A. Neumanni ; Pelomys Harringtoni, with three bright buffy 

 lines down its belly; and Lepas Fagani, a dark, shorteared Hare allied to L. 



Whytei. A new genus, Muricidus, was instituted for Riippell's u Mu$ imberbis." 



— A communication was read from the Hon. Walter Rothschild, F.Z.S., 

 in which he stated his opinion that the Elk described by Mr. Lydekker as 

 Alces bedfordiae was, if not a valid species, a distinct subspecies, and not a 

 variety as had been supposed by Mr. H. J. Elwes.
