of which the fourth joint has a dentate margin, the grooved fingers 
have the opposing margins serrate and the tips pointed, and the upper 
and lower margins of the hand serrate. The ambulatory legs have the 
seale-like markings noted by Guerin. 
The specimen, a male, was obtained by Mr. T. H. Dale.

Several other references may be gleaned from the above by anyone 
in a position to give a clear synopsis of this interesting genus. The 
shape of the carapace with the arrangement of the three antero-lateral 
teeth and the relative length of the ocular peduncles offer trustworthy 
characters. The fringing and coating of various parts with sete are 
perhaps not so much to be depended on. The difficulties of the subject 
are illustrated by the fact that Alcock makes Jf. imermis, A. Milne- 
Edwards, a synonym of MM. conveaus, Stimpson, while Miss Rathbun 
considers them quite distinct.
