first two pairs of walking legs distally, proximal 

 rugae on hands with reticulate maroon pattern on 

 yellowish background; anterior shield mottled 

 tan; eyestalks banded alternately with maroon, 

 yellow, and tan. 



Habitat.— Fifteen to 124 fathoms. 



Type locality. — Guadeloupe. 



Known range. — Off Oregon Inlet, N.C., 17 

 fathoms (Cerame- Vivas, Williams, and Gray, 

 1963), to Port Aransas, Tex.; through West 

 Indies to Guadeloupe. 



Remarks. — Until recently this species was 

 known only from beyond the 100-fathom curve 

 in the Carolinas, but it has been collected in 

 shallow water north of Cape Hatteras (Cerame- 

 Vivas, Williams, and Gray, 1963). 



Subfamily Pagurinae 



The chief distinguishing characters for this 

 group are given in the Key to Subfamilies of 

 Hermit Crabs. 



KEY TO GENERA OF PAGURINAE IN THE 

 CAROLINAS 



a. Fingers opening and closing horizontally ; no paired 

 appendages on abdomen of either sex. 

 b. Vas deferens of male not protruding in form of a 



tube Pagurus (p. 125). 



bb. Vas deferens of left side protruding, and coiled in 



a spiral Spiropagurus dispar (p. 133). 



aa. Fingers opening and closing obliquely ; vas deferens 

 of male not protruding ; a pair of appendages on first 

 abdominal segment of female only 



Pylopagurus (p. 133). 



Genus Pagurus Fabricius, 1775 



Provenzano, 1959, p. 393. — Hemming, 1958b, p. 163. 



KEY TO SPECIES IN THE CAROLINAS 



a. Eye scales unarmed or with single subterminal spine, 

 b. Length of eyestalk not more than 3.5 times its 

 greatest width. 



c. Width of major chela less than one-half length, 

 d. Chelipeds subcylindrical, relatively smooth on 

 outer surface ; eye scales somewhat rounded 

 distally, dorsal surface shallowly excavated 



longicarpus (p. 125). 

 dd. Chelipeds not subcylindrical, relatively spiny 

 on outer surface ; eye scales rounded distally 

 but not excavated on dorsal surface 



defensus ( p. 127 ) . 



cc. Width of major chela more than one-half length, 



one or both chelae broad and flattened. 



d. Dactyl of major chela with sharply produced 



angle on medial margin ; no depressed spot at 



base of immovable finger of either chela 



pollicaris (p. 128). 



dd. Dactyl of major chela without sharply pro- 

 duced angle on medial margin ; a depressed spot 

 (or spots) at base of immovable fingers of chelae 



impressus (p. 129). 

 bb. Length of eyestalk at least 4 times its greatest 



width annulipes (p. 130). 



aa. Eye scales armed with two or more spines. 



b. Rostrum acute pygmaeus (p. 131). 



'bb. Rostrum obsolete orcvidactylus (p. 132).

Recognition characters.— Anterior shield of 

 carapace subcordate, truncate posteriorly, about 

 as broad as long. Rostrum obsolete, hardly as ad- 

 vanced as lateral projections of front. Eyestalks 

 stout, 2-3 times longer than broad, much shorter 

 than width of anterior shield, cornea dilated ; eye 

 scales with concave, oval anterior lobe armed with 

 a subterminal spine. Antennular peduncles ex- 

 ceeding eyes by about half length of terminal 

 article. Antennal peduncles exceeding eyes by
