Munidopsis scahra resembles Jf. sharreri (A. M. Edw.), but may be at once 

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

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



Munidopsis tanneri Fax.

Bull. Mus. Comp. Zo6L, XXIV. 187, 1893. 



Carapace flat, quadrangular, covered with squamous setiferous 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 antcro-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. Antenna? 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; 

 pleuroB narrow, angles rounded. 



Length, 41 mm.; length of carapace, 23.5 mm.; breadth, 16.5 mm.;

This species is nearly related to M, scahra^ but differs from the latter 

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

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

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

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