OXTSTOMATOUS AND ALLIED CRABS OF AMERICA 3^43 



margin of intestinal region bilobed, lobes more distinctly marked in 

 cf than in 9 . Front thick, bilobed. Entire lower surface granulate. 

 Outer margin of arm irregularly bilobed, distal lobe the larger; hands 

 dilated, outer margin cristate; fingers thin, flat, grooved. Legs 

 cristate, crests dentate or narrowly lobed. 



In one small cf (19361), the anterior angles of the cardiac region 

 are not joined closely by the branchial surface, resulting in two smaU 

 orifices, which lead into the large cavities. 



Color. — Like dead piece of coral overgrown with purplish and green- 

 ish algae and patches of red ones. Hands perhaps of a natural greenish 

 cast; reticulations around whitish areas greenish or pale bice green; 

 above articulation of fingers faint vinaceous-pink ; fingers dull china 

 white. Legs dirty white, merus with whitish spots and greenish 

 reticulations and with vinaceous median cross bar, as have also carpus 

 and propodus across middle of upper side. Eyes not distinguishable 

 from rest of coloration of body. Under parts dirty whitish, abdomen 

 greenish, darker in pits; marldngs much as in Hay's photograph 

 {loc. cit.), perhaps vinaceous-cinnamon. Eggs transparent drab color, 

 with black eye. 



Habit. — Very readily plays dead. 



Measurements.— Male (19362), length 12.2, width 14.8 mm.; 

 female (55191), length 17, width 21.7 mm. 



Range.— North Carolina to Puerto Rico; IK to 10 fathoms.

Diagnosis. — Carapace trigonal, much broader than long. Two 

 large posterior orifices, invisible in dorsal view. 



Description. — Length of carapace about two-thirds of width; 

 posterior margin nearly straight to the outer end where it forms a 

 large, arcuate lobe on the side, which is nearly half as long as the 

 carapace; a little farther forward on the margin a small blunt lobe or 

 tooth, followed by a broad, shallow, triangular lobe extending to the 

 branchiohepatic sinus. Hepatic region prominent, defined by a 

 broad shallow groove; subhepatic region sharper, conical, appearing 

 a little more than a right angle from above. Carapace laterally very 

 convex and a little uneven; covered with flat, crowded granules; a 

 small transverse elevation on anterior branchial region. Posterior 

 hollows large, openings rhomboidal. The two blunt frontal lobes are 

 separated by a depression, from which a single line of raised granules 

 extends backward some distance on the gastric region. The under 

 side of the body and the appendages are very rough. Palms bluntly 

 carinate; merus with three stout conical, blunt lobes on upper surface.
