3. On some Crustaceans from Mauritius. By E. J. Miers, 

 F.L.S., F.Z.S., Assistant in the Zoological Depart- 

 ment, British (Natural History) Museum. 



[Received December 12, 1883.] 



(Plate I.) 



M. V. de Eobillard having recently forwarded to the Zoological 

 Department a small but interesting collection of Crustaceans from 

 Mauritius, the following notes on the species are laid before the 

 Society, in continuation of the reports upon Crustaceans from the 

 same locality sent by M. Robillard on two previous occasions 1 . 



The collection comprised in all examples of only eighteen species ; 

 but of twelve of these, which were retained for the Museum, several 

 have been hitherto desiderata in the collection ; and one species, 

 which I have designated Callianassa martensii, is, I believe, new to 

 science. "With three or four exceptions, however, the species have 

 a wide oriental distribution. 



Besides the species selected for the Museum, which are referred 

 to in the following notes, there were in the collection specimens of 

 Mewethius rnonoceros, S'ehizophrys serratus, Trapezia ferruginea, 

 Neptunus sunguinolentus, Thalamita crenata, and Podophthalmus 

 vigil. 



The following is a list of the species included in the present report ; 

 those marked with an asterisk are such as I believe to be now 

 recorded for the first time from Mauritius. 



Actceodes pubescens (M.-Edw.). Indian Ocean (v. Martens). 



Chlorodius niger (Forskal). Oriental Region.

A specimen (adult, female) referred to this species agrees with the 

 descriptions and figure in nearly every thing except in the coloration,
