 fathoms. 



Type locality. — Nouvelle Hollande. 



Known range. — Near Beaufort, N.C., to Cedar 

 Keys, Fla. ; Bahamas to Florianopolis, Santa 

 Catarina, Brazil ; Bermuda. 



Remarks.- — Ovigerous females have been re- 

 ported from March to August in the Caribbean 

 area, and from November to January in the West 

 Indies, Venezuela, and Brazil (Rathbun, 1925;

Pearse (1932b), working at Dry Tortugas, 

 listed the copepod Anthiacus intermedins from 

 the gill lamellae (accidental guest) and a tape- 

 worm plerocercoid, Rhyrtchobothrus, from the 

 viscera, and (in Wilson, 1935) reported a few 

 specimens of Cancrincola jamaicensis Wilson 

 from the branchial cavity of this crab.

Recognition characters. — Carapace depressed, 

 tuberculate, and granulate, area at inner angle of 

 branchial region finely granulate; intestinal re- 

 gion with four large, equal tubercles. Anterolat- 

 eral wall with two laminiform processes, one on 

 hepatic, one on branchial region; hepatic process 

 with anterior end acute, projecting outward and 

 occasionally forward in large individuals, some- 

 times with outward-projecting tubercle at middle 

 of upper edge; a spine between and below level of 

 hepatic and branchial processes; branchial process 

 not rimmed nor sharply defined. Branchial re- 

 gion with three spines, one forming posterolateral 

 angle occasionally doubled. Posterior margin with 

 row of tubercles increasing in size medially. Ros- 

 tral horns slender, directed forward, about one- 

 sixth length of remainder of carapace. Basal arti- 

 cle of antenna with spine at outer angle about 

 half length of rostral spines. Orbits small, circu- 

 lar, with closed fissures; eyes small; preocular 

 spines acute, about half as long as antennal spines. 



Merus of chelipeds with dentate and laminate 

 dorsal crest; carpus tuberculate; palm less than 

 twice as long as broad; fingers widely gaping, im- 

 movable finger strongly curved downward. Walk- 

 ing legs sparsely hairy and with a few spines and
