locality, but whose contents were evidently from the west 

 American coast. 



S. I. Smith had seen specimens he referred with doubt to 

 this species from the Abrolhos (Hartt), Caravellas, province 

 of Bahia (Hartt), Aspinwall (F. H. Bradley), Florida Keys 

 (Gibbes), and Bermuda (J. M. Jones). Milne-Edwards and 

 Heller record it from the Mediterranean, Krauss from Natal, 

 Hilgendorf from Mozambique, and Hoffmann from Reunion.

This specimen bears a considerable external resemblance to 

 G. chiragra, but may be distinguished by the following cha- 

 racters. There is a small median keel between the innermost 

 or submedian prominences of the penultimate postabdominal 

 segment ; there are seven closely-placed prominences on the 

 upper surface of the terminal segment, the median being the 

 largest, and the others becoming successively smaller ; the 

 median and submedian are usually armed with spines ; there 

 are moreover six marginal spines (the outermost of these are 

 obsolete in G. chiragra) ; the outer of the two spines of the 

 basal prolongation of the uropoda has a small tooth on its 

 inner margin near its base ; and these spines are longer and 

 slenderer than in G. chiragra. 



Hab. Indo-Pacific Region.
