the first pair of legs with a few minute tubercles, and a few similar 

 tubercles usually on the same joint of other pairs, each tubercle 

 bearing setae.

Near M. stibserratus. Carapax slightly tuberculate; cardiac tubercle 

 simple, postmedian and intestinal also distinct and simple ; second 

 of the lateral teeth slightly double, the first and third simple ; beak 

 entire, of moderate length ; lateral margin with three teeth ; the first 

 simple, the second a little double. Eyes rounded at apex, having at 

 apex, both anteriorly and posteriorly, a small spine. Hand oblong, 

 surface very minutely areolate, fingers for the most part contiguous, 

 teeth six in number. Second pair of feet longer than the first.

Length, slightly over two lines. 



The character of the eyes and the areolate character of the surface 

 of the hands, as observed under a high magnifier, distinguish this species 

 from the subserratus. The same areolate character is seen in the 

 exterior maxillipeds, upon the other joints of the legs, and appears at 

 first sight to be a granulation of the surface. Each minute areola ap- 

 pears to have a prominent point at centre, looking like an obsolete 

 spine. The teeth of the fingers only extend along the apical half of 

 the inner margin, the rest being very nearly a straight line.
