CRUSTAC E A. 



wards, which much resembles our curtknanus. The specimens we 

 describe differ from Edwards's areolatus in having the same number of 

 antero-lateral teeth as the wigulatm (that is, five and not four), the 

 posterior legs are not "presque lisses," but granulous, and the anterior 

 legs are small tuberculous.

Related to ungulatus, the areolets being very distinct and prominent, 

 antero-lateral margin five-dentate, front between outer antenna 4 

 four-lobed, eight posterior feet pubescent and spinulous above. 

 Areolet 2 M decompound, 4 L more or less divided. Anterior feet 

 armed with very small pointed tubercles, moveable finger unarmed. 

 Penult segment of male abdomen a little oblong.

Length of carapax, eight lines; greatest breadth, eleven and a half 

 lines ; ratio of length to breadth, 1 : 1-44. Other specimens are smaller. 

 They are all characterized by very small pointed tubercles on the 

 arm and hand, instead of obtuse warts like the iingulotus; and the 

 areolets of the surface are usually much broken into subordinate eleva- 

 tions, which is especially seen in 2 M and 4 L. The young in iingu- 

 latus appear to resemble the montlculosus in the acute points of the 

 hand; but in specimens five or six lines in length the prominences 

 are obtuse and wart-like. The arm projects but little more than in 

 the curtimauus.
