penultimate and terminal segments uniformly covered with 

 numerous closely -placed slender spines, which are longest near 

 the posterior margin. The eyes are scarcely dilated distally ; 

 the basal scales of the antenna? remarkably small ; the rapto- 

 rial limbs large, with the dactylus strongly dilated at base ; it 

 terminates in a slender arcuate spine, and is armed on the 

 inner margin of the thickened portion with three spines placed 

 near to one another. The uropoda are very small. 



Hab. Bay of St. Vincent. 



On account of the dilated dactylus of the raptorial limbs, it 

 appears to me that this species must be placed in Gono- 

 dactylus ; but it presents many affinities with Lysiosquilla. I 

 have seen no specimens.

This species, according to M. A. Milne-Edwards, differs 

 from G. scyUarus by the form of the rostrum, which, although 

 enlarged at base, ends in a point, and by the existence of a 

 lamellate median carina on the terminal postabdominal seg- 

 ment, which is much less elevated than in G. cultrifer. 



Hab. Batavia (Bleeker). I have seen no specimens.
