visable that they should be clothed. During the last week the 

 cold has been much greater than they have hitherto experienced ; 

 but they have, thanks to the kindness of Mr. Bourchier, everything 

 that can be desired. 



" These four Giraffes, three males and one female, are so interest- 

 ing and so beautiful, that I shall exert myself to the utmost to be of 

 use to them. It is possible that they may breed; already I observe in 

 them some tendency towards mutual attachment. They are capable of 

 ■walking for six hours a day without the slightest fatigue. — G. T." 



Mr. Gould, at the request of the Chairman, exhibited a specimen 

 of the Trogon resplendens, Gould, and one of the Trog. pavoninus, 

 Spix ; and stated that he was indebted to the kindness of M. Nat- 

 terer, who was present at the Meeting, for the opportunity of de- 

 monstrating, by the juxtaposition of the Birds, the correctness of 

 the determination which he had made in regarding them as distinct 

 species. Mr. Gould directed particular attention to the several 

 characters and distinguishing marks which he had pointed out to 

 the Society on March 10, 1835, and which had subsequently been 

 published in the * Proceedings,' part iii. p. 29, and again dwelt 

 especially on the fact that in Trog. resplendens the hinder feathers of 

 the back, which are fully 3 feet in length, hang gracefully far away 

 beyond the tail; while in Trog . j}avoninus the lengthened feathers of 

 the back are rarely equal in length to the tail ; in only one instance 

 has M. Natterer known them, in the latter bird, to exceed the tail 

 by so much as a quarter of an inch. 



The reading was concluded of a paper " On the Anatomy of the 

 Lamellibranchiate Conchiferous Animals, by Robert Garner, Esq., 

 F.L.S.," a portion of which had been read at the meeting on No- 

 vember 24, 1835. 



Founded principally on the author's individual observations, 

 which have extended to the animals of several genera the anatomi- 

 cal structure of which is hitherto insufficiently known, this commu- 

 nication embodies also much information derived from the works of 

 Poli, Cuvier, Bojanus, Home, M. de Blainville, and others. It is so 

 arranged as to constitute a condensed memoir on the subject to which 

 it is devoted, comprehending a summary of all that is yet known 

 respecting it. 



After some general remarks on the high importance of a know- 

 ledge of the structure of the animals that form those shells which 

 have at all times attracted the attention of the curious, but to an 

 acquaintance with which many naturalists, until of late years, have 

 been content to limit themselves, Mr. Garner proceeds to speak of 

 the position of the animal with respect to the shell ; and thence to 

 describe the variations in the form of the animal which occasion those 

 appearances in the shell on which rest the primary subdivisions
