Munidopsis spinipes, sp. n. 



This species agrees with M. Gvodridgei and M. Milleri, 

 var. (above described), amongst Indian species in having the 

 eyes absolutely immovable, yet furnished with neither spine 

 nor spinnle. 



The carapace is convex, subqnadrangular, about the same 

 breadth in front and beliind. A pair of large spines are 

 situated anteriorly on the gastric region. There is no 

 vestige of a spine or spinule on the cardiac region or poste- 

 rior border of the carapace. The rostrum is short and 

 styliform ; towards its tip there is obscure microscopic 

 serration on its lateral margins. The supra-antennal spines 

 arc of good size. On the lateral border there are three large 

 spines and one or two spinules, situated thus : — One spine 

 at the antero-lateral angle, a second at the anterior angle of 

 the triangular area lying between the two divisions of the 

 cervical groove, and the third immediately behind the poste- 

 rior division of the same groove ; behind the second spine 

 and lying with it between the two divisions of the cervical 

 groove there may^ be one or two spinulcs, diminishing in size 

 from before backwards. 



The abdomen is smooth and has a few scattered hairs ; 

 the second tergum is transversely bicarinatCj and the third 

 transversely grooved. In the telson on either side between 

 the two lateral plates there is a small calcareous patch, 

 much tlie same as in M. ciliata. 



The basal joint of the antennule has one spine and three 

 spinulcs : the spine (large) on the outer side and two spinules 

 on the inner side oi' the distal end of the joint ; whilst the 

 third spinule is on the far side of the globular swelling on 

 the upper and outer surface of the basal joint. On the inner 

 edge of the merus of the external maxillipeds there are two 

 large spines. 



The chelipcds are subequal and much longer than (nearly 

 a third as long again as) the fully extended body. The arm 

 has three longitudinal rows of spines and four large terminal 

 spines ; the wrist has two rows of spines and four terminal 

 spines ; both edges of the outer surface of the palm are 

 spinosc. The fingers are not straight, but meet throughout 

 their length ; the fixed finger is finely serrated, and a little
