WiJliam 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 PeUcani, Lam., 

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

 teresting on account of the evidence aiForded 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 fuU 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, wheu not more than one half or three ąuarters gro\vn, is 

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

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

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



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



Characters were read of the Vespertilionida observed in the centrai 

 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 foUov.ing are the species characterized : 



Rhinolophus armiger, Hodgs. 

 Rhin. tragatus, Ej. 

 Pteropus leucocephalus, Ej. 

 Pter. pyrivorus, Ej . 

 Vespertilio form osa , Ej . 

 Vesp. fuUginosa, Ej. 

 Vesp. labiata, 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 by Mr. Hodgson was read, which has 

 also been published in the ' Journal of the Asiatic Society of Cal- 

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

 Species of Cerviis, discovered by Mr. Hodgson in 1825, andindicated 

 in liis Catalogue by the local name of Buhraiya." 



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

 as constituting an important link in the chain of connexion bet\veen 

 the Deer of the Rusan and of the Elaphine groups : possessing in the 

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

 of the principai characteristics of the latter group ; but agreeing
