longer than propodi, longest in first pair ; second 

 left leg markedly different from others, with 

 dactyl and propodus broadened, fringed with 

 hairs, and with a lateral longitudinal ridge paral- 

 leled by a groove, ridge crossed with numerous 

 rugae. 



Measurements. — Length of carapace (medium 

 sized individual) : 31 mm. (Verrill, 1908). 



Color. — Walking legs with broad, transverse 

 bands of red; legs, fingers of hands, and inside 

 surfaces of chelipeds reticulated with fine red 

 lines (hence, descriptive specific name) ; scalelike 

 tubercles of hand and rugae of second left leg 

 blue to purple; eye scales sometimes white (Pro- 

 venzano, 1959). 



Habitat. — Often found on sand and grass flats, 

 on mud bottom, and in baited traps (various 

 authors). Shells inhabited sometimes bear sponges 

 or coelenterates (Holthuis, 1959). Shallow water 

 near shore to 50 fathoms ; rarely to 200 fathoms. 



Type locality. — Guadeloupe. 



Known range. — Off Beaufort Inlet, N.C. 

 (Cerame- Vivas, Williams, and Gray, 1963) ; 

 through West Indies to northeastern Brazil; 

 Bermuda. 



Remarks. — Ovigerous females have been re* 

 ported from northeastern Florida in June, from 

 the Virgin Islands in March and May (Pro- 

 venzano, 1961), and from northeastern South 

 America in April, May, July, and September.

 Dardanus insignis: Verrill, 1908, p. 446, text-fig. 60; pi. 26,

Recognition characters. — Anterior shield of 

 carapace longer than width of front, with 

 .scattered clumps of setae, and roughened slightly 

 near anterior and anterolateral margins. Anterior 

 margin with rostrum wanting; lateral projections 

 on front triangular, thickened, prominent, and 

 hairy on frontal edge. Eyestalks stout, slightly 

 constricted in middle, extending almost to tips of 

 antennal peduncles, a pencil of hairs at base of 

 dilated cornea; eye scales prominent, well sepa- 

 rated, serrated distally with a strong medial pair 

 of spines separated from a smaller more lateral 

 series of four spines by a notch obscured by a 

 pencil of setae. Antennular peduncles with base 

 of terminal article exceeded by eyestalks. Acicles

long, reaching to base of cornea, with a few spines 

 and hairs arranged in a spiral line originating on 

 inner surface at base and curving across dorsal 

 surface to termination on lateral surface near tip. 



Chelipeds heavy, left larger than right, covered 

 with ciliated, tuberculate rugosities becoming 

 bolder and more diagonal distally on hands and 

 immovable fingers; movable finger of major chela 

 with ciliated rugosities somewhat diagonal, those 

 on minor dactyl irregularly arranged; opposed 

 edges of fingers with heavy white teeth, tips 

 black; spine on crest of meri, outer surface of 

 carpi, and hands, largest spines on upper medial 

 border ; a row of spines on lower medial border of 

 merus and ischium. First two pairs of walking 

 legs strong, with rugose pattern similar to 

 chelipeds and forming herringbone pattern on 

 outer surface of propodus of large second left 

 walking leg; dactyls of these walking legs with 

 crest of spines dorsally, that of second left leg 

 with crest of spines dorsally and vent rally, and 

 continued below on propodus. Third and fourth 

 walking legs reduced and specialized. 



Measurements. — Male: length of carapace, 38 

 mm.; anterior shield, length, 17.5 mm., width, 

 15.5 mm. 



Color. — Ground color yellowish; rugosities tan 

 near body, becoming maroon on chelipeds and
