this species must be described, I propose along with that

Two specimens of this species recently described from 

 types procured by Lieut. Chaves in the Azores were found 

 by me among stones below high-water mark at Gorgulho, 

 near Funchal.

Tliis new species has been submitted to M. A. Dollfus, who 

 lias decided that it is not described, and has sent me the 

 following description, together with the figures which illus- 

 trate it : —

 witli granulations, especially on the earlier segments; dorsal 

 surface finely setiferous throughout. Cephalon having the 

 lateral frontal lobes rounded ; central lobe well developed, 

 triangular, rounded, the summit blunt. Epistome a little 

 convex, but without any true median tubercle. Eyes with 

 fourteen ocelli. Exterior antennas equalling the length of 

 lialf the body ; the flagellum almost as long as the preceding 

 joint, its first articulation half as long as the terminal. Poste- 

 rior margin of the perajon having a slight lateral sinuosity at 

 the sides. Pleon witii the lateral processes well developed ; 

 the first plcopods in the male with tlie exopodite broader than 

 long and somewhat obtuse. Pleotelson much longer than
