and projects far beyond the frontal teeth : the hood-like fold, oa 

 either side of the front, that covers the base of the eyestalks, has its 

 angles not pronounced. 



The lateral margins of the carapace are denticulated up to a stoutish 

 tooth near the middle of the branchial border. 



The abdomen of the male has both on the second and on the third 

 terga a transverse row of 3 tubercles, the middle one large rounded and 

 polished, the lateral ones smaller and acute, and one stout tubercle in the 

 middle line on the fourth tergum : in the female the third fourth and fifth 

 terga are transversely carinate, the carinse being denticulate, and one 

 tooth on the third and 4th terga, in the middle line, being much en- 

 larged ; the second tergum is also transversely carinate, but bluntly and 

 indistinctly. 



The chelipeds of the adult male are asymmetrical, the hand of one 

 side being greatly swollen and being a good deal broader than long : in 

 both chelipeds the ischium merus and carpus have the outer surface 

 covered with spinules and acute granules. 



The second true leg is more than twice the length of the fourth, and 

 nearly three times the length of the carapace: its carpus like that of the 

 first is traversed longitudinally by two granular crests. 



Large males have the carapace 36 millim. long, and 34 millim. in 

 extreme breadth : ovigerous females have the carapace 25 millim. long 

 by 24 millim. broad. 



In the Indian Museum collection are very numerous specimens 

 from Mergui, Andamans, East coast of India from Ganjam to Palk 

 Straits, and Persian Grulf. 



As Miers states, there can be little doubt that Linnseus' diagnosis 

 (Mus. Lud. Ulr. p. 452) refers to this species. But De Haan long 

 before (Faun. Japon. Crust, pp. 121, 139) had bespoken the identity of 

 D. dorsipes and D. quadridens and had noticed the confusion by earlier 

 authors of Cancer dorsipes of Linneeus with Cancer dorsipes of Fabri- 

 cius.
