206 CRUSTACEA. 



wards, which much resembles our curtimanus. The specimens we 

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

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

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

 legs are small tuberculous. 



CHLORODIUS MONTICULOSUS. 



C. ungulate affinis, areolis valde distinctis, margine antero-laterali 5-den- 

 tato, fronte inter-antennali k-lobato, pedibus 8 posticis paulo pubescen- 

 tibus et supra spinulosis. Areola 2 M decomposita, 4 L phis minusve 

 divisa. fkdes antici tuberculis parvulis subacutis armati, digito 

 mobili inermi. Segmentum abdominis maris penultimum parce ob- 

 langum. 



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

 antero-lateral margin five-dentate, front between outer antenna 1 

 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 : 144. Other specimens are smaller. 

 They are all characterized by very small pointed tubercles on the 

 arm and hand, instead of obtuse warts like the ungulatm; 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 ungu- 

 latm appear to resemble the monticulosus 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 curtimanus.
