Smith.] 284 [February 3, 



terior edge arcuate; last tootli narrow, its apex slender and booked 

 forward. Inferior lateral regions pubescent and tbickly granulate. 

 Inferior margin of the orbit thin, its edge as seen from below contin- 

 uous but somewhat concave, and the inner angle projecting forward 

 to a line with the inner angle of the superior margin. 



Chelipeds unequal, carpi and hands slightly granulous above; 

 larger hand stout, the dactylus curved strongly and without a strong 

 basal tooth within; smaller hand with the fingers slender and some- 

 what spoon-shaped at the tips; all the fingers with slight longitudinal 

 impressed strise. Ambulatory feet pubescent along the edges, the 

 dactyli in the posterior pair much shorter than the others. Terminal 

 segment of the male abdomen narrower than the penult, about ihree- 

 Iburtlis as long as broad, the sides convex and the tip rather broadly 

 rounded. Fingers black, lighter at the tips, the black sj^i'^-^^^'^g ^'"^^ 

 upon the palm. 



Length of the carapax In a male, 18.6 millim; breadth, 2G.8; ratio, 

 1:1.44. 



New Haven, Conn., common. Found in abundance at Egmont 

 Key, Fla., by Col. E. Jewett. There are also specimens in the Socie- 

 ty's collection. 



This species, as well as the next, has very likely been confijunded 

 with the young of P. Herhstli, but it is very different, and is easily 

 distinguished from it b}' the mcjre depressed carapax, the very differ- 

 ent teeth of the antero-lateral margin, and by the entire absence of 

 the tootb at the base of the dactylus in the larger hand.

 Vol. I, p. 58, 1817 (non Herbst). 



Carapax narrow, strongly convex, microscopically granulous and 

 slightly pubescent; regions distinctly marked and protuberant. 

 Front very prominent and slightly deflexed, the edge thin, strongly 

 arcuate as seen from above, with a distinct median incision, the lat- 

 eral angles rounded and not at all projecting. First lobe of the an- 

 tero-lateral margin composed of the angle of the orbit coalesced with 

 the second normal tooth, not at all prominent, slightly concave, the 

 inner angle slightly projecting to form the angle of the orbit, outer 

 angle short and rounded; third normal tootb projecting much more 

 than the lobe in front of it, and truncate; fourth tooth prominent, 

 somewhat triangular and separated from the third and fifth by rather 

 deep triangular notches; fifth, or last, narrow, triangular, much thick-
