A. TERAO : 



long as the carapace measured in the median line, provided with 

 stout long bristles on the ventral side ; each bristle bearing on the 

 ventral side a series of paired setae growing out vertically. 



Left cheliped twice as long as the carapace measured in the 

 median line ; the whole cheliped almost hairless except on the dorsal 

 setose surface of merus, and somewhat glossy on surface in spite 

 of the granulation ; upper border of hand and carpus well-defined ; all 

 joints elongate ; hand about twice as long as broad, index acute. 



Right cheliped wanting. 



Second and third pairs of legs setose, spinulose on the upper 

 border of propodus and carpus ; dactylus longer than propodus, with 

 a longitudinal groove on the outer surface. 



Note : A male specimen from Prov. Sagami is in Mr. R. Saitô's collection. The species is 

 closely allied to D. gramtlalus Micrs, from which it differs however in the ophthalmic 

 scales being apically spinulose instead of being entire. The present species is also near 

 to D. brevirostris Stimpson, but this differs from it in the carpus of left cheliped being 

 short and of a triangular shape.
