Figitbe 97. — Clibarvarins vittatus (Bosc). A, anterior part of body in dorsal 

 view, X 1.6; B, third leg, X 3.2 (after Holthuis, 1959). 



Recognition characters. — Anterior shield of 

 carapace subquadrate, a few fine hairs along 

 lateral margin. Front with rostrum acute, tri- 

 angular, slightly more prominent than lateral 

 projections. Eyestalks almost as long as width of 

 anterior shield, nearly cylindrical, cornea not 

 dilated, right eyestalk occasionally slightly 

 shorter than left; eye scales narrow, approxi- 

 mated at tips, but well separated at bases, margin 

 with one to four spines, terminal largest. Anten- 

 nular peduncles as long as eyestalks. Antennal 

 peduncles reaching to at least three-fourths length 

 of eyestalks; acicles acute, with three to five ter- 

 minal spines, flagella reaching tips of walking 

 legs. 



Chelipeds equal, sparsely hairy; hands thick, 

 inflated, twice as long as broad, covered thickly 

 above, sparingly below, with somewhat blunted 

 spines darker than color of hands and with 

 bundles of stiff hairs springing from bases; fin- 

 gers opening horizontally, heavy, toothed and 

 somewhat gaping at base, cutting edges corneous, 

 extending along upper side; carpus as long as 



palm. First and second walking legs exceeding 

 chelipeds by over half length of dactyls, tips 

 corneous; two distal articles with numerous 

 bundles of hairs. Third and fourth walking legs 

 reduced; third subchelate; fourth very small, 

 chelate, and turned on back. 



Measurements. — Length of carapace: male, 32 

 mm. ; female, 29 mm. 



Color. — Greenish to dark brown with longi- 

 tudinal stripes of gray to white; antennular pe- 

 duncles light above, dark laterally, with orange 

 flagella ; propodus of walking legs with four pairs 

 of light, longitudinal stripes continuous with 

 similar stripes on dactyl and carpus, one of ven- 

 tral stripes usually somewhat diffuse (Proven- 

 zano, 1959). 



Habitat. — Common on harbor beaches, espe- 

 cially on borders of mud flats (Pearse, Humm, 

 and Wharton, 1942) ; often on rock jetties or high 

 on bay shores (Whitten, Rosene, and Hedgpeth, 

 1950) ; waterline to a few feet. 



Type locality. — Coasts of Carolina.
