types; tolerates somewhat lowered salinities of 

 estuaries; near low-tide mark to 23 fathoms 

 (Schmitt, 1935a). 



Type locality. — Beaufort Harbor, N.C. 



Known range. — Vineyard Sound, Mass., around 

 Florida peninsula to Alligator Harbor; Cuba; 

 Puerto Rico. 



Remarks. — Ovigerous females have been re- 

 ported in September from Massachusetts (Thomp- 

 son, 1903), and from February to April, and Au- 

 gust to September in Florida (Provenzano, 1959). 

 Thompson described four zoeal, a glaucothoe, a 

 postlarval, and a number of adolescent stages at 

 Woods Hole. The only difference he found be- 

 tween P. annulipes and P. longicarpus in larval 

 development was the slightly smaller size of the 

 former. 



Pagurus annulipes may occur a few miles off- 

 shore, for it has been found in the stomachs of 

 flounders {Paralichthys dentatus) taken 15 miles 

 east-southeast of Oregon Inlet, N.C, in 20-fathom 

 water along with numerous juvenile Cancer irro- 

 ratus.

Recognition characters. — Anterior shield of 

 carapace longer than wide. Rostrum acute, slightly 

 in advance of lateral projections, each bearing a 

 terminal spine. Eyestalks shorter than width of 

 anterior carapace, wide at base, tapering toward 

 cornea; eye scales armed along medial margin 

 with four or five spines. Antennular and anten- 

 nal peduncles extending slightly beyond cornea; 

 unarmed acicle reaching base of cornea. 



Chelipeds unequal, right much larger than left, 

 both with long but very fine hairs and forward- 

 projecting spines. Major chela suboval, margin 

 armed with strong spines, upper surface covered 

 with smaller, nearly blunt spines; carpus with 

 six very sharp spines on upper anteromedial sur- 

 face, two additional spines more laterally placed, 

 and a short row of spines along lateral margin. 

 Minor chela much reduced, twice longer than 

 broad, upper surface with many blunt spines, 

 some forming two central rows; tips of fingers 

 corneous, spooned; carpus with double row of 

 large spines on upper surface. Walking legs with

dactyls shorter than propodi, approximately five 

 ventrally placed spines in addition to terminal 

 point, propodus with about seven less conspicuous 

 spines, all articles with long sparse setae. 



Measurements. — Length of carapace: male, 3 

 mm. 



Habitat. — Shallow water to 45 fathoms. 



Type locality. — "La baie de la Zocappa," near 

 Santiago, Cuba. 



Known range. — Off Little River, South Caro-
