60 — 
kindly sent to him lor his opinion thereon. After a careful 
examination of the specimen, I have no hesitation in pro- 
nouncing it to be some species of Sphinx which has been ar- 
rested in the stage of development from the pupa to that of 
its perfect condition. In the British Museum there is a large 
collection of insects that have at the various stages of de- 
velopment been destroyed by the growth offunguous mat- 
ter ; this occurs most commonly in the Caterpillar state in 
the Lepidoptera — but in IL/menoptera equally in their per- 
fect condition ; hence a species of Wasp has been figured and 
named Pobistas crinila. The specimen you have sent will 
be an intetesting addition to the Museum collection, and I. 
am requested to convey to you the thanks of the authorities 
for it.”

M. de Kobillard donne la description d'une coquille nou- 
velle de Maurice. 
‘ ; J1 y a plusieurs mois, dit-il, qu’une coquille fort cu- 
rieuse a etc trouvee dans nu poisson, ne paraissant appartenir 
a aucun genre bien determine, 
“ Elle a etc envoyee a Londres pour ctre examinee par 
les Savants Conch iliologistes qui s’y trouvent, elle a etc dc- 
crite par M. Henry Adams, dans la seance de la Societe Zoo- 
logique de Londres du 2 Janvier dernier, sous le nom de 
Lrptoconus Du Saveli. 
“ M. Adams dit qu’elle parait appartenir augroupc Phas- 
muconitx, de Morch, par rapport a la nature de son lest et a la 
maniere dont il cst colore, et quo pour la forme elle a de la 
ressemblanco avec les especes du sous-genre Nubecula, des 
Cones.
