I found this pretty species in one of the bottles kindly entrusted 

 to me by Prof. Milne-Edwards; it was labelled '•Voyage de M. 

 Blosseville, 1832." I have not been able to leam the locality from

 the discoverer. It is preserved in the Museum of the Jardin des 

 Plantes.

 to whom I am indebted for many interesting specimens of Crustacea.
