consequently know not what proficiency they may have made in entomology. Should 

 this notice fall into their hands, they may learn from it the precise localities of many 

 species which are desiderata to most collections, and hy notifying their capture in the 

 4 Zoologist,' will find a short-hand way to making a collection, in the offers of insects 

 in exchange, they will receive from other collectors. They will find the hippopotamus 

 a safe card, and one on which they are sure to win. — H. T. Stainton ; Mountsjield,

Proceedings of the Zoological Society. 



Evening Meeting, January 14. — Professor Owen, V.P., in the chair. 



The following papers were read : 



' Beinarks on the highest limit of Animal Life in the Alps ;' by Dr. Schlagintweit. 



' Further Remarks on Balamiceps rex ;' by Mr. Gould, in which he developed its 

 generic characters and affinities. 



Mr. Gaskoin communicated the descriptions of twenty new species of Columbella, 

 and one of Cypraea, chiefly from his own collection and that of Mr. Cuming. 



Mr. Bowerbank read a paper ' On a New Species of Pterodactylus from the Chalk 

 Formation.' The specimen consisted of seven inches and a quarter of the snout, of a 

 head, which if restored on the scale of that of Pterodactylus longirostris, would indi- 

 cate a length of twenty-five inches and a half; there are sockets for twelve teeth on 

 each side ; the distance between each tooth is about one inch and a half of the long 

 diameter of the sockets, which are nearly equidistant from each other. The head is 

 exceedingly narrow ; at the eleventh pair of teeth from the tip of the snout it is but 

 three quarters of an inch wide. One of the first pair of teeth remains in its socket ; 

 the whole of the other large teeth are displaced, but two of them are imbedded in the 

 chalk near the sockets. The largest of them exceeds an inch and a quarter in length, 

 they are slightly curved, smooth, and hollow at the base. A very fine radius and 

 ulna of Pterodactylus, from the collection of Mrs. Smith, of Tunbridge Wells, and a 

 similar pair of bones from the collection of Mr. Charles, of Maidstone, were also ex- 

 hibited. The length of the former bones, the author states, would exceed ten inches, 

 and the latter would be nearly seventeen inches. A tabular view of the length of 

 each bone of the wing, and of the total distance from tip to tip was given, by which 

 it would appear that the amount of expansion of the following species would be, 

 P. brevirostris nine inches ; P. longirostris one foot ten inches ; P. crassirostris three 

 feet two inches ; P. Bucklandi four feet seven inches ; P. grandis five feet five inches ; 

 P. giganteus six feet seven inches. Mrs. Smith's specimen ten feet two inches, and 

 Mr. Charles's specimen sixteen feet six inches. The author believes the latter to be 

 of the same species as the head described, and which he proposes to designate Ptero- 

 dactylus Cuvieri, in honour of the great naturalist whose labours shed so much light 

 on the history of these wonderful reptiles.
