the following particulars. 1. The chelipeds are much longer. 2. The carapace 

 is hairier, flatter and broader. 3. The rostrum is relatively shorter and slopes 

 gently downwards, its curve being nearly continuous with that of the anterior 

 part of the carapace ; its extreme tip is upturned. 4. The eyes are cylindrical 

 and slightly curved. 5. The spine at the antero-lateral angle of the carapace 

 is much smaller and directed forwards and not obliquely outwards at an angle 

 of about 45. 6. The cervical groove is bounded posteriorly on the lateral 

 margin, by a small spine; in M. stylirostris both groove and spine are very 

 inconspicuous. 7. The merus of the cheliped has two rows of spines on its 

 upper surface, one on the inner the other near the outer margin. 8. All the 

 joints of the 2nd, 3rd and 4th thoracic legs are hairy. 9. The ridge bounding 

 the transverse furrow of the 2nd and 3rd abdominal terga is spinulous in the 

 middle line, as is also sometimes that of the 4th. 



Colours in life were the same as those of M. stylirostris; milky orange 

 dorsally, white ventrally, eyes yellow. 



As in M. stylirostris, there are no epipodites on any of the appendages 

 behind the external maxillipeds. 



The length of the largest male, from tip of rostrum to end of telson is 54 

 millim., its chelipeds being 92 millim. 



Arabian Sea, 406, 457-589, 459 and 531 fathoms : Bay of Bengal, 480 and 

 594-225 fathoms. 



There are in the collection two small specimens, of this species, dredged 

 off the Andamans in 500 fathoms, in which the abdominal terga have no spines.

Differs from all known Indian species in having the eyes absolutely im- 

 movable, yet furnished with neither spine nor spinule. Its nearest relative is, 

 perhaps, the Philippine species M. Milleri, Henderson. 



Carapace subquadrangular, convex, slightly broader behind than in front, 

 its regions well delimited, its posterior half deeply sculptured transversely. 



Gastric region with some not very conspicuous squamiform sculpture and 

 with a pair of large spines situated anteriorly ; a spine on either side of, and a 

 pair of spinules in the middle of, the anterior cardiac region. 



Rostrum short, simple, rather slender, smooth. A large acute spine on the 

 anterior margin of the carapace ; lateral borders with two large spines and a 

 spinule, posterior border smooth.
