Besides the absence of spinulcs on tlie transverse cnrinre 

 of the second and tliird abdominal terga, the surface of the 

 carapace generally is smoother and its ridges and rugre less 

 prominent.

This specimen agrees with M. Goodridgei (Alcock and 

 Anderson) and M. spinipes (sp. n. et sub descr.) in differing 

 from all other Indian species in having the eyes fused, 

 ventrally, immovable, and fnrnished Avith no spine or spinule. 

 This variety also comes from much the same depth and 

 locality as M. Goodridgei : the former from 568 fathoms, west 

 of Ceylon ; the latter from 430 fathoms, off the Travancore 

 coast. 



This specimen differs from Henderson's description of 

 M. Milleri in the following points : — 



(1) Gastric area armed with one pair of spines and three 

 (instead of one) pairs of spinulcs. These spinules are 

 arranged one pair behind the other and all lying on the 

 circumference of an imaginary circle on the posterior half 

 of the gastric region, thus : — the first pair situated behind 

 the spines; the second pair behind these and wider apart, 

 placed on the lateral margins of the gastric region ; the third 

 pair close together near the posterior margin of the gastric 

 region. 



(2) Rostrum is not spinulous, but subsqnamiforra. 



(3) Instead of a spinule being present on the anterior 

 border of the carapace behind the autennal peduncle, the 

 largest spine on the carapace is situated there. 



(4) Inner margin of palm is spinose and the uppor surface 

 is not smooth and glabrous, but has a few scattered tubercles 

 and tufts of long silky hairs. 



(5) There is a well-marked spinule in the centre of the 

 triangular dilated area of the carapace, lying between the 

 two divisions of the cervical groove. 



This specimen differs from M. Goodridgei chiefly in : — 



(1) Posterior border of carapace spinnlose. 



(2) An extra spine on the lateral border of the carapace. 



(3) Three extra pairs of spinules on the gastric region and
