Remarks. — Though this species has a tremen- 

 dous recorded range in depth, it is usually found 

 well inside the 100-fathom mark. On September 

 6, 1953, an ovigerous female was collected from 

 wharf pilings in Bogue Sound near Bogue Inlet, 

 N.C. 



Otherwise, ovigerous females are known or have 

 been reported in the western Atlantic from Febru- 

 ary in the Gulf of Darien, throughout spring and 

 summer in North and Middle America, and north- 

 ern South America, to November off the Amazon 

 River (U.S. National Museum records; Hilde- 

 brand, 1954; Holthuis, 1959; Rathbun, 1925). 



Subfamily Ophthalmiinae 



Orbit consisting, if complete, of a supraocular 

 eave and a postocular spine; intercalated spine 

 lacking . . . [but] . . . longer spinous outgrowths 

 on supraocular eave and on postocular spine for 

 most part present. Shape of body elongate, some- 

 what truncate in front, often provided behind 

 with a median spine or outgrowth (Balss, 1929).

aa. Orbit completely unprotected below; eyes protected 

 above by a lamellate projection consisting of supraocu-

Recognition characters.— Carapace as broad as 

 long in adult males, longer than broad in other 

 individuals, narrow behind in males, broader in 

 females, roughened with tubercles of different 

 sizes, and adorned with scattered hooked hairs. 

 Frontal teeth forming rostrum more advanced 

 i orbital angles. Anterolateral margins armed 

 five strong teeth, exclusive of postorbitai 

 tooth; first tooth largest, second and third sub-

equal, fourth and fifth much smaller, second oc- 

 casionally bilobed. Orbits small, tubular, deep. 

 Antenna short, with stiff hairs on borders; basal 

 article lamellate, forming floor of orbit; second 

 article flat, short, and broad; third article smaller, 

 flattened. 



Chelipeds of adult male from 1.5 times to 

 nearly twice length of body; merus subcylindri- 

 cal; carpus and hand more or less compressed 

 and distinctly angled along margins; fingers of 

 adult male hollowed into spoon shape, touching 

 only at extremity. In female and young male, 

 fingers short and weak, evenly dentate, with mar- 

 gins in contact. 



Abdomen of both sexes with seven free seg- 

 ments. 



Measurements. — Carapace: male, length, 26 

 mm., width, 24 mm.; female, length, 18 mm., 

 width, 17 mm. 



Variations. — In females and young males the 

 carapace is more tuberculate than in old males, 

 the lateral teeth are sharper, and the last two 

 teeth are more prominent than in mature males. 



Color. — Dirty brownish yellow (Desbonne in 

 Rathbun, 1925). 



Habitat. — This species has been found on a 

 variety of bottoms including mud, sand, shell- 

 sand, shell, rock and coral, and grass (Rathbun,
