The body and appendages though on the whole very hairy, are not 

 quite so hairy as in D. dorsipes ; the chelipeds have the hair confined 

 almost entirely to their borders, especially the upper border ; the 1st 

 and 2nd pairs of legs are almost hairless in the female, and in the 

 male have the hair confined to the anterior border of the merus and 

 the posterior border of the merus carpus and propodite ; and hair is 

 absent from the convexities of the thoracic sterna. 



Extreme length of carapace considerably less than extreme breadth. 



The surface of the carapace, when denuded, is either perfectly 

 smooth, or smooth in the middle and finely granular at the sides and 

 in front : the regions are well defined by grooves. 



The hood-like fold covering the base of the eyestalks, on either side 

 of the front, has its inner or anterior angle dentiform : the spine at the 

 external orbital angle is broad and suddenly acuminate, and projects to 

 but not beyond the level of the frontal teeth : the spine at the inner 

 canthus is slender, straight, and acute, and projects well beyond the 

 frontal teeth. 



The lateral borders of the carapace are sometimes granular, but 

 never denticulate. 



The abdomen of the male is unarmed : in the female the 3rd-5th 

 terga are coarsely and bluntly carinate, the carinas of the 4th and 5th 

 being finely granular. The chelipeds when denuded have all their 

 joints quite smooth : those of the adult male are asymmetrical just as 

 in D. dorsipes. 



The second true leg is much more than twice, often three times, 

 the length of the fourth, and 2f to 2| times the length of the carapace : 

 its carpus, like that of the first is bicarinate, the carinse being granular 

 under the lens but not to the naked eye. 



Large males have the carapace 29 millim. long and 34 millim. in 

 extreme breadth : ovigerous females have the carapace 20 millim. long 

 by 24 millim. broad. 



In the Indian Museum are very numerous specimens from the East 

 coast from the mouth of the Hooghly to Madras, and a few from the 

 Andamans. It is common on soft muddy bottoms, and I have rarely 

 found it without a protective bivalve shell and sea -anemone.

Almost exactly resembles D. facchino (Herbst), but has the cara- 

 pace a little more grauular and with scanty or obsolete pubescence.
