Figure 95. — Paguristes spinipes Milne Edwards. A, an- 

 terior part of body in dorsal view, approximately X 4 

 (after Benedict, 1901) ; B, right chela, outer surface, 

 5 mm. indicated. 



siderably exceeding rather obtuse lateral projec- 

 tions. Eyestalks considerably longer than greatest 

 width of front but not quite so long as length of 

 anterior shield, somewhat contracted in middle 

 and slightly bent laterally, not much dilated 

 distally; eye scales acuminate. Antennular pe- 

 duncles extending to tips of, or a little beyond, 

 eyestalks. Antennal peduncles extending about 

 two-thirds length of eyestalks; acicles straight, 

 terminated by a spiny fork, and with two or 

 three spines on internal and external borders. 



Chelipeds subequal and similar in form, narrow 

 but massive; hands less than half as broad as 

 long; upper surface of hands and carpi covered 

 with conical spines, many with corneous tips, 

 strongest on superointernal border; fingers more 

 than half as long as whole of propodus and ter- 

 minating in corneous tips, opposed edges with 

 numerous teeth. Walking legs extending a little 

 beyond chelipeds, ornamented with tufts of hair 

 most numerous and rigid on dactyls; dactyls 

 regularly curved and half again as long as pro- 



podus; crest of spines on carpus and propodus 

 extending along a portion of dactyl of first walk- 

 ing legs, but reduced, and present on carpus only 

 of second walking legs. 



Measurements. — Length of carapace : adults, 17 

 mm.; immatures, approximately 5 mm. (Milne 

 Edwards and Bouvier, 1893, in part). 



Variations. — The eyestalks are somewhat 

 shorter than the front in young individuals but 

 much longer in adults'; they are frequently un- 

 equal in length. The cardiac region is calcified 

 but the areas lateral to it are variably calcified 

 (Milne Edwards and Bouvier, 1893). 



Color. — A spot of orange red on external and 

 internal faces of first walking legs, less definite 

 on two following pairs; occasionally, traces of 

 red coloration on anterior part of cephalothorax 

 (Milne Edwards and Bouvier, 1893). In alcohol, 

 nearly white, each cheliped with a conspicuous 

 orange-yellow band across merus and a faint trace 

 of a similar band on each walking leg (Hay and 

 Shore, 1918). 



Habitat. — This essentially deep-water hermit 

 has been taken from shells of Cassis and Xeno- 

 phora; 73 to 350 fathoms. 



Type locality. — Grenada, 92 fathoms. 



Known range. — Gulf Stream south of Cape 

 Lookout, N.C., off Cape Canaveral and Sarasota, 

 Fla. ; Barbados to Pernambuco, Brazil. 



Remarks. — This species has rarely been col- 

 lected north of Barbados.

 1959, p. 388, fig. 11 (rev.). 



Recognition characters. — Anterior shield of 

 carapace longer than broad; rostrum triangular, 

 in advance of lateral projections of front. Eye- 

 stalks slender, straight, as long as greatest width 

 of anterior shield; eye scales separated by ros- 

 trum, anterior process armed with three or four 

 spines (occasionally two) decreasing in size from 

 median spine outward. Antennular peduncles 

 reaching to base of cornea or slightly beyond. 

 Antennal peduncles reaching to three-fourths 

 length of eyestalks; flagella not reaching to tips 

 of chelipeds, sparsely setose; acicles obscured by 

 hairs, armed with two spines on inner edge and 

 at least three on outer edge.
