rostrum lacks the lateral spines, and the supraocular spines are much longer, 

 reaching beyond the eyes. From M. irrasciK. M. Edw., which is also an irides- 

 cent species, M, refidgens differs in the shape of the hand, in the relatively 

 shorter median rostral spine, which is provided with lateral spines, etc.

The carapace of this species is rather flat ; the rostral spines are sca- 

 brous, the supraocular reaching to a point beyond the eyes; there is a promi- 

 inent spine on the gastric area behind each supraocular spine, another on 

 each side behind and external to these, and a pair of very small ones on the 

 median line at the base of the rostrum ; besides these there are about four 

 small spines on the anterior half of the carapace. The anterior lateral angle 

 of the carapace is truncated, the lateral border seven-spined. The pleurae of 

 the abdomen are rounded, short, and broad ; the second abdominal seii?ment

is furnished with a transverse row of about eight spines, the rest of the seg- 

 ments being destitute of spines; the terga of the second to the fourth seg- 

 ments are very smooth behind the central transverse fossa). The first joint 

 of the antenna is armed with a long spine, the second joint with one on each 

 side. There is a minute spine at the antero-infcrior angle of the carapace. 

 The chelipeds are robust, setose, and spiny ; merus spiny on upper and inner 

 parts ; carpus spiny on all sides ; the hand is furnished with two rows of 

 spines on the lower side, another along the middle of the outer face, and 

 three irregular series along the upper side ; both the fingers are spinulose. 

 Ambulatory limbs setose, spiny along the superior and inferior edges. 



In small specimens the supraocular spines may be shorter than the eye- 

 stalks.
