tout not entirely in our specimen. The telson has a ni,edio-dorsal 

 triangular elevation, and is broadly truncated, with only two 

 spines on either side above the truncation, between which and 

 tie lower spines there is a faint projection of the margin. The 

 rostral plate is, as described by IMilne-Edwards, cordiform and 

 very pointed. 



Length, 175 mm., or 7 inches from apex of rostrum to distal 

 margin of telson- 



Locality: — " Squilla procured at Durban (from Durban 

 Museum)." A specimen nearly twelve inches long, sent me by 

 Mr. W. R- Forrest from! Antigua, differs from the form above 

 ■described in not having the rostral point produced, in having the 

 fifth pi eon segment denticulate along the hind margin, except at 

 the centre, the sixth denticulate in an arched proximal band and 

 roimd the distal margin, and the telson with three spines on' 

 each side, and the truncate portion cut into five square teeth on 

 one side and six on the other side of a small median emargina- 

 tion- Milne-Edwards, in his description, says that the hind 

 margin of the telson is armed with three little obtuse " dente- 

 litres " on each side of a little n'vedian emargination- We may 

 infer, therefore, that the species is subject to some variation in 

 minor details.
