Habitat. — On sandy bottom, grassy flats, or 

 pilings; occasionally found in sponges (Wass, 

 1955) ; 6 to 18 fathoms. 



Type locality. — Florida. 



Known range. — Off Diamond Shoals, N.C., to 

 east coast of Florida ; western Florida from Sani- 

 bel Island north to vicinity of Alligator Harbor ; 

 Port Aransas, Tex.

Recognition characters. — Anterior shield of 

 carapace subcordate, scarcely longer than wide, 

 truncate posteriorly. Rostrum obsolete, about as 

 long as rounded lateral projections of front. Eye- 

 stalks nearly straight, shorter than front, slightly 

 constricted in middle, cornea not dilated; eye 

 scales flat, broad, and rounded but with one or 

 two spines on anterior border. Antennular pedun- 

 cles exceeding eyestalks by about one-third of last 

 article. Antennal peduncles reaching about to, or 

 beyond, tip of eyestalks; acicles slender, curving 

 outward, reaching about middle of last article of 

 antennal peduncle; flagella exceeding major che- 

 liped. 



Chelipeds unequal, right much larger than left. 

 Major cheliped long, subcylindrical, moderately 

 and evenly granulate and ciliate above, except 

 subspinose in large individuals; tips of fingers 

 hooked, dactyl less than one-half length of hand; 

 carpus nearly twice as long as broad, spinulose 

 along inner margin. Minor cheliped much shorter, 

 compressed, thickly ciliate and spinulose above; 

 hand slightly shorter than carpus; fingers shorter 

 than palm, with cutting edges distally, gaping at 

 base. First and second walking legs with dactyls 

 longer than propodi, legs slender, compressed; 

 carpus with a distal spine on upper border. Third 

 legs much reduced; fourth pair smaller, turned 

 on back. 



Measurements. — Length of carapace: male, 5 

 mm.; female, 4 mm. (Provenzano, 1959); Wass 

 (1955) found a specimen with a carapace length 

 of 7 mm. 



Variations. — This is a small species. Males tend 

 to attain larger sizes than females, and this is

accompanied by a proportionately larger cheliped 

 (Provenzano, 1959). 



Color. — White to gray with brown pigment 

 band around each article of walking legs; an- 

 tennae with broad purple bands alternating with 

 narrower white bands, occasionally with poorly 

 defined longitudinal stripes on legs (Provenzano, 

 1959). 



Habitat. — Fairly common on a variety of bot- 

 tom types in Massachusetts, but not so common in 

 the Beaufort Harbor area of North Carolina; 

 abundant in Thalassia beds in southern Florida, 

 seemingly preferring soft, sandy bottom to other
