Mr Henry Aclams believes the shell, which has never 
been found except in the (e Phillipine Islands,” is the 
Ovula birostris — a similar specimen was also found alive 
at Grand Bay and sent to Mr Bewsher. 
But Mr Robillard's most curious discovery was that o^ 
a shell found in the stomach of a fish, and which appeared 
at first sight not to belong to any well known genus. 
Mr Henry Adams to whom it was forwarded for exami- 
nation, read a description of it to the Zoological Society 
of London at the meeting of 2nd January last, under the 
name of Lepioconus Du Saveli. 
At the same meeting he gave a description of a new 
species of terrestrial shell discovered at Reunion Island, 
by our colleague M. C. E. Bewsher, on the mountain 
which rises above St. Denis, at an elevation of 1000 feet, 
Mr II. Adams bestowed on the shell the name of Stylo- 
don Beivsheri. 
We are also indebted to Mr Robillard for having dis- 
covered the cause of the great blight on the mango-fruit. 
He has found that it proceeds from a very small but most 
brilliant coloured Dipt'er. 
It deposits its eggs in the pulp of the fruit, which soon 
after becomes tainted and assumes a dark colour whilst 
externally the Mangoe does not lose its natural colour. 
A Lepidopter of the genus Sphinx? v r as several times 
presented to the Society by Dr Edwards, Mr Ev. Dupont 
and other members, without it being possible to account 
satisfactorily for the singular state in which it was found. 
This Sphinx is always found settled on a leaf to which 
it adhers. The body is covered with bristling threads re- 
sembling hair and simulating a microscopic vegetation. It 
was curious to notice these asperities on the skin of an 
insect whose body is generally bright and polished, or 
covered with a silky down, as are usually the body and 
the wings if the Lepidoptcrs.
