Muiiidopsi-s scabra resembles M. sliarreri (A. M. Edvv.), but may be at once 

 distinguished from the latter b}' the shortness of the ocular spines, and the 

 groat development of the spiny-pointed tubercles of the carapace.

Carapace flat, quadrangular, covered with squamous setif'erous tubercles 

 which have a tendency to develop spiny points on the gastric region. This 

 is especially true of a transverse row of six on the anterior part of this 

 region. The rostrum is triangular and horizontal. There is a prominent 

 spine on each side of. the anterior margin of the carapace between the eye 

 and the antenna, another at the antero-lateral angle, and two or three on the 

 side of the anterior branchial lobe ; the hind border of the carapace is den- 

 ticulated. A small spine over the eye. Antennae shorter than the body ; one 

 spine on the outer side of the first joint, two lateral and one superior on the 

 second and third joints. Cheliped (present in only one specimen) long, slen- 

 der ; merus and carpus many-spined ; propodite spiny along the upper and 

 lower margins ; tips of fingers enlarged and denticulated. Ambulatory 

 limbs: a prominent row of spines on the upper edge of the merus and 

 carpus, propodite and dactylus devoid of spines. Abdomen without spines; 

 pleurae narrow, angles rounded. 



Length, 41 mm. ; length of carapace, 23.5 mm. ; breadth, 15.5 mm. ; 

 rostrum, 6 mm.

This species is nearly related to M. scnhm, but differs from the latter 

 species in having the cariipace broader and flatter, with squamous tubercles 

 which are not produced into points, except a few on the gastric area. The 

 spine between the Qya and the antenna is longer ; the propodites of the 

 ambulatory legs are smoother, with no well-developed spines.
