1834. Dodea hybrida and muricata, Milne Edwards, Hist. Nat. Crust., 



vol. 1, pp. 294, 295. 



1895. Dodea muricata and hybrida, Alcock, J. Asiat. Soc. Bengal, 



vol. 64, pt. 2, pp. 230, 231. 



Under the last reference Alcock supplies more of the biblio- 

 graphy and a comparison of the two species which suffices to 

 my mind to make the second name superfluous, though it is the 

 one which would apply to our specimen were such distinction 

 really needed. 



From the little notch in the rostrum to the apex of the hind- 

 most spine the carapace measures 38 mm. Across the widest 

 part the breadth is 29 mm. The elevations in the median line 

 longitudinally are blunt. In the right cheliped the chela is 

 scarcely longer than the finger of the second peraeopod, with the 

 breadth of the palm equal to the length of the thumb, both this 

 and the rather longer curved finger being considerably shorter 

 than the palm. The specimen is a male, with the left cheliped 



mssng.

Extensively tuberculate carapace rotundiform except at points of 

 greatest breadth. Pleon of male of seven segments, third segment 

 the broadest, seventh with narrowly rounded apex. Front of carapace 

 between the orbits about one-fourth of the greatest breadth. Mandi- 

 bular palp two-jointed. Third joint of third maxillipeds strongly 

 tuberculate, distally widened, fourth joint narrow at base, distally as 

 wide as the third joint, its anterior margin produced into a strong 

 tooth outside the fifth joint. Chelipeds unequal, cristiform. Ambu- 

 latory limbs with fourth, fifth aud sixth joints not expanded but 

 strongly and in part spinosely tuberculate, the seventh joint not 

 tuberculate but felted with minute spiuules, and ending in a small 

 curved horn-like nail. The male organ of the second pleopod verv 

 long and slender with acute apex.
