150 A. Alcock — Carcinological Fauna of India. [No. 1, 



grannlar sculpture of the upper surfaces of these joints and of the 

 meropodites is concealed by a close short spongy growth of hair. 



Colours in spirit yellow, fingers brown. 



ijength of carapace 175 millim., breadth 26 millim. 



A single male from off the Malabar Coast 29 fms. 



This species (?) may perhaps be only a variety of A. nodulosa. I 

 have noticed it separately, and have figured it, on account of the 

 resemblance it bears to Herbst's Cancer polydora ( Krabben III. ii. 33, 

 pi. lii. fig. 2).

Carapac6 f as long as broad, only moderately convex, the lobulation 

 distinct but not convex, covered with strongly convex well-isolated 

 smooth polished tubercles, which are largest on the branchial regions 

 and are smallest posteriorly, where also they become somewhat squami- 

 form. On the antero-lateral borders are four (excluding a tubercle 

 of the supra-orbital series) large tubercles, much similar to those on 

 the branchial regions, but more prominent (almost stalked) and with 

 larger tops (almost pisiform). 



Exposed surfaces of wrist and hand covered with tubercles much 

 like those of the branchial regions, but more prominent : on the lower 

 outer surface of the hand they become almost squamiform : a few 

 tubercles at the distal inner corner of the arm. 



Exposed surfaces of carpal and propodal joints of legs covered 

 with stout thorns : smaller thorns on upper edge of meropodites, and 

 still smaller ones on surface of dactyli except on the claw. 



Front broadly bilobed : each lobe with an S-shaped curve to the 

 edge and with the outer angle pronounced. 



Fingers short, blunt pointed, liardly hollow at tip. 



The basal antennal joint stops far short of the inner angle of the 

 floor of the orbit. 



Colours in spirit light yellow, fingers dark brown. 



In the Indian Museum are 3 specimens from Australia but none 

 from India. It is included here on the authority of Dr. J. R. Henderson.
