hand, which has only the inner edge of the inflated palm slightly spinate : the 

 fingers are very short, very broad and strongly spooned at tip. The 2nd to 4th 

 legs are acutely spinate in every joint except the dactylus, which however has 

 the usual dentations on its posterior margin. There are no epipodites on any of 

 the thoracic legs. 



Length of fully extended body 39 millim., of chelipeds 26'5 millim. Bay of

Plate III. fig. 2. 



Closely related to M. spinoculata A. M. Edw., from which it seems to differ 

 only in having the chelipeds and legs armed with a few spines on the merus and 

 carpus. Young specimens are hardly to be distinguished from M. pi]n.--<i, 

 Henderson. 



Rostrum about a third the length of the rest of the carapace, nearly 

 triangular, carinated, simple. 



Frontal border of carapace oblique, with a very strong supra-antennal 

 spine : lateral border with a very strong spine behind the antero-lateral spine 

 and an obscure denticle behind the posterior branch of the cervical groove : 

 posterior border unarmed : dorsum with transverse ripple-like markings, which 

 are most distinct postero-laterally, but without any spines. 



Abdomen quite unarmed. 



Eyes absolutely fixed : the eyestalk prolonged beyond the eye, on the inner 

 side, as a spike more than half the length of the rostrum. 



Merus of external maxillipeds with two little denticles on the ventral 

 margin. 



Chelipeds of the male much shorter than the body, faintly rugulose trans- 

 versely and sparsely hairy, as are the legs : ischium with a strong spine at the 

 inner distal angle, merus with a distal ring of 4 spines and a longitudinal dorsal 

 row of spinules, carpus with a strong spine at the inner distal angle, hands 

 unarmed, the fingers shorter than the palm, blunt, and strongly spooned. Legs 

 about as long as the chelipeds, the merus spinose along the anterior border and 

 with a terminal spine on the posterior border, the carpus with a pair of terminal 

 spines on the anterior border, the dactylus short and stout. 



There are no epipodites on any of the legs. 



The abdominal appendages of the male are comparatively well developed.
