HIPPOLYTE HEMPRICHII. 107 



the two bands of the chelipedes are marked with more or 

 less numerous spots of a dusky gray , and often the beau- 

 tiful red colour of these bands is more or less extensive- 

 ly substituted by a light grayish colour. In one speci- 

 men I observed a remarkable monstrosity: the orbits being 

 united with one another , the substance of their walls pass- 

 ing over and pressing down the rostrum, the orbits being 

 almost rounded anteriorly without spines.

A single fine female specimen is in the collection. The 

 second joint of the carpus of the second pair of legs is 

 distinctly longer than the first.

Six specimens of this species were collected , but I think 

 it most probable this form is identical with the com- 

 mon Hippolyte gibberosus M. Edw.
