127. PINNIXA BREVIPOLLEX, new species. 



(Plato XLIII, Iig. «.) 



Pollcx a short spine; dactyl tramtierse; a transverse cardiac crest. 



Carapace uneven, i)unctate, the gastric and hepatic regions bounded 

 by very deep furrows; cardiac region high and crossed by a transverse 

 crest, surmounted in the male by two triangular tubercles, comi)ressed 

 from before backward, and subacute; in the female the crest is lower, 

 blunt, and divided in the middle by a very shallow sinus. I'rontal and 

 hei)atic regions granulated. Subhepatic region with a small depressed 

 area or tubercle surrounded by a deep groove. Anterolateral margin 

 of the branchial region armed with from four to six distant blunt 

 spinules beginning at the lateral angle and followed near the hepatic 

 region by smaller tubercles or granules. Inferior margin of the cara- 

 pace granulated. The margins of the frontal lobes extend oblicjuely 

 backward from the middle. The antenme exceed the width of the 

 front. The sides of the nuile abdomen from the third to the fifth seg- 

 ments, inclusive, converge regularly; those of the sixth joint are still 

 more convergent, joint very short; terminal joint narrowest, broader 

 than long, rounded. The last two joints of the palpus of the maxilli- 

 peds are oblong; the terminal joint is articulated near the base of the 

 second joint, and overreaches it considerably, overlapping the sternum 

 and touching the tip of the abdomen in the male. 



Chelipeds wanting in the male; in the female thoy are nionodactyl. 

 Propodus very broad, fUittened, increasing in width distally, its great- 

 est width equaling the superior length; superior margin slightly 

 convex; lower margin slightly convex for its proximal two-thirds;
