In invertebrated animals, especially those which inhabit the sea, 

 Mauritius is rich. Among the ^nnelida, M. Lienard, sen. has de- 

 scribed an Amphilrite, which he believes to be new : he has also 

 described the Amph. vohtticornis and Ampli. splcndula, Lam., together

 lacustrine Erpobdella has been described by M. L, Desjardins, who 

 has preserved to it the trivial name of sex-lmeata, doubtingly given 

 by MM. Quoy and Gaimard. Three ne\v species of Crustacea, of the 

 genera Lupa, Plagusia, and Cancer, have been described by M. Lie- 

 nard, jun.: and M. De Lisse, sen., has proposed to regard as the type 

 of a new genus the Homard sans cornes of the fishermen ; to this 

 group he gives the name of ScyUibacus, and places it between Sct/llu' 

 rus, Fab. and Ibacus, Vėr. The species is named ScyUibacus orieutalis.

The Radiata which have been described, are a species of Fistularia, 

 Lam., and a nevv species of Cephea, the Ceph. lamellosa, so named by
