Jan. 22. — A letter was read, addressed to Charles Telfair, Esq., 

 Corr. Memb. Z.S., as President of the Mauritius Natural History 

 Society, by M. Goudot of Madagascar. It contained an account 

 of a remarkable phenomenon exhibited by the larvae of a species of 

 Aphrophora (Cercopis), which attach themselves to a tree of the 

 genus Morus, not uncommon in the vicinity of Tamatave, in the 

 island last named. 



Mr. Bennett called the attention of the Society to a stuffed spe- 

 cimen of an Antelope, from the southern part of the peninsula of 

 India, which had been presented to the Society several months 

 since by Mr. Telfair. He was disposed to regard it as the young 

 of the Indian Antelope, Antilope Cervicapra, Pall. 



Specimens were exhibited of the adult male of the lineated Phea- 

 sant, Phasianus lineatus, Lath , and of two immature birds of the 

 same species : for the whole of these the Society is indebted to 

 George Swinton, Esq., Corr. Memb. Z.S. Mr. Gould made some 

 observations upon them.

 Cornwall, of Ianthina vulgaris, Lam., and of Velella limbosa, Lam., 

 both animals of rare occurrence on the English coast, and chiefly 

 met with floating in tropical or warmer seas.
