In the 2nd and 3rd legs the only joint whose anterior border is distinctly 

 spinulose is the carpus. 



From D. rectimanus and investigator is, with which it agrees in having the 

 outer surface of the hand granulous and traversed by a serrated ridge running 

 nearly parallel with the upper border of the palm, it is at once distinguished 

 by the deflexed fixed finger and the second longitudinal carina on the outer 

 surface of the hand. 



Length of carapace between 6 and 7 millim. 



inhabits broad-mouthed shells of Pleurotoma.

Carapace elongate, nearly smooth, its antero-lateral borders finely 

 serrulate. Rostrum a slender spinule slightly longer than the ophthalmic 

 scales. 



Eyestalks remarkably long, considerably longer than the anterior border 

 of the carapace, almost as long as the peduncle of the antennules and very 

 much longer than that of the antennae. Ophthalmic scales spinulose at the 

 antero-internal angle. 



Antennal peduncle remarkably short, barely reaching to the base of the 

 terminal joint of the antennular peduncle. Antennal acicle a serrated spinule 

 Iparely reaching to the base of the terminal joint of the peduncle. 



Chelipeds pilose. Left cheliped much the larger : when denuded its 

 outer surface is smooth, except for a longitudinal series of 3 or 4 spines on 

 the outer surface of the carpus : the upper border of the merus is serrulate, 

 and the lower outer border of the merus and the inner and anterior borders 

 of the wrist and the upper border of the palm are spinulose: a median 

 longitudinal finely granulous bulge, or low carina, traverses the outer surface 

 of the palm. 



The 2nd and 3rd legs reach, or slightly surpass, the tip of the left cheliped : 

 they are setose and, except for a spinule at the far end of the anterior border 

 of the carpus, smooth : the dactyli are longer than the propodites. 



Length of carapace about 4 millim.
