Synopsis of the Species. 



A. Spine on antero-external angle of basal joint of 

 external antenna:^ nearly as large as the rostral horns ; 

 spines on the hepatic region are almost as large as 

 antennal spines ; two large spines on branchial margin.

B. Spine on antero-external angle of basal joint of 

 external antennae much smaller than the rostral horns ; 

 hepatic spines much smaller than these; one small spine 

 on branchial margin. — {^M. bicornutiis.)

The body and the legs are slightly hairy ; there are 

 stiff, curved hairs on the rostrum, on the projecting parts 

 of the carapace, and on the upper surface of the legs. 

 These hairs hold a great number of foreign bodies, under 

 which the crustacean lives. The carapace is wide in 

 the branchial regions. The regions are knobby, and 

 have on their projecting parts some tubercles, which on 

 the branchial regions become spines. On the posterior 

 border there is a row of pearl-like knobs extending as 

 far as the legs of the fourth pair. The superior orbital 

 border has in front a small spine. The lateral border 

 of the carapace has a series of spines. There are two 

 spines on the hepatic region, three of the same size on 

 the epibranchial lobe, and two large spines on the 

 metabranchial lobe. 



The front is formed of two moderately long, diverging
