William Yarrell, Esq., in the Chair. 



A Note was read, addressed to the Secretary by J. B. Harvey, 

 Esq., Corr. Memb. Z.S., and dated Teignmouth, April 24, 1836. 

 It referred to a series of specimens of Rostellaria Pes Pelicani, Lara., 

 presented by the writer to the Society, and which he regards as in- 

 teresting on account of the evidence afforded by them of the curious 

 fact, that in the shells of this species the outer lip is most thickened 

 at a time antecedent to the full development of the shell ; absorption 

 of the incrassated part of the lip taking place as the animal advances 

 in age. " This series," Mr. Harvey remarks, " clearly shows that 

 < the shell, when not more than one half or three quarters grown, is 

 much thicker than when all the processes are perfected : and that, 

 when each process has a groove or channel in it, the shell is quite 

 thin, and has arrived at its full period of growth." 



The shells referred to in Mr. Harvey's letter were exhibited. 



Characters were read of the Vespertilionidee observed in the central 

 region of Nepal ; being a communication transmitted to the Society 

 by B. H. Hodgson, Esq., Corr. Memb. Z.S. They have already been 

 published in the ' Journal of the Asiatic Society of Calcutta'. 



The following are the species characterized : 



Rhinolophus armiger, Hodgs. 

 Rhin. tragatus, Ej. 

 Pteropus levcocephalus, Ej. 

 Pter. pyrivorns, Ej . 

 Vespertilio formosa , Ej. 

 Vesp. fulighiosa, Ej. 

 Vesp. lab lata, Ej. 



Mr. Hodgson's characters of these species are accompanied by re- 

 marks on the habits of the several genera of Bats which are repre- 

 sented by them in the district in which they occur. 



A second communication bj'' Mr. Hodgson was read, which has 

 also been published in the ' Journal of the Asiatic Societ}"^ of Cal- 

 cutta'. It was entitled " Specific Name and Character of a New 

 Species of Cervus, discovered by Mr. Hodgson in 1825, and indicated 

 in his Catalogue by the local name of Bdhraiya." 



The animal to which this paper refers is regarded by Mr. Hodgson 

 as constituting an important link in the chain of connexion between 

 the Deer of the RusOn and of the Elapkine groups : possessing in the 

 numerous snags into which the summit of its horns are divided one 

 of the principal characteristics of the latter group ; but agreeing
