carina on the dorsal surface. Telson broad and rounded, ecarinate, 

 pubescent above, extremity rounded. Length one and one-half 

 inches. 



The single specimen which is in the Museum of the Boston Society 

 of Natural History was brought from Zanzibar by Dr. Charles Pick- 

 ering. 



This form clearly belongs to the Gebidse as limited by Dana, but it is 

 clearly separated from all known genera by well marked characters : 

 from Gfebia and its allies by the absence of the antennal scale and the 

 chelate second pair of pereiopoda; from Axius in the absence of the 

 antennal scale and from Gebiopsis A. Milne-Edwardsjby the characters 

 of the second pair of walking feet. Its position seems to be inter- 

 mediate between Axius and Gebiopsis.

When at work at the collections of the Philadelphia Academy I 

 was unsuccessful in my search for the type of this species, which was 

 supposed to have been brought from the west coast of America. In 

 the collection which formed the basis of Dr. Kandall's paper, there 

 were specimens from California and from the Sandwich Islands, and 

 it is possible that some transfer of labels took place here as well as in 

 the case of one of the grapsidce. This supposition is rendered the 

 more probable from the fact that this species has never been reported 

 from our shores, except by Randall, and so far as I am aware, it has 

 never been seen by carcinologists since his day. In going over the 

 collections of the Boston Society, I found, however, three imperfect 

 specimens from Mauai, Hawaiian Islands, presented by Dr. Winslow, 

 which agree well with Dr. Randall's description, and one of which 

 fnrnished the illustration accompanying the present article. It is a 

 valid member of the genus, and can readily be identified by the figure 

 and description.
