110 BULLETIN 129^ UNITED STATES NATIONAL MUSEUM 



smooth, fingers finely denticulate on prehensile edges and, as in the 

 feniale of trispinosus, without a large tooth. Ambulatory legs short 

 and hairy. 



Measurements. — Female, holotype, length of carapace 13, width 

 9 mm. 



Range. — Sombrero, Florida Strait, 54 fathoms. 



Material examined. — A somewhat smaller female in the National 

 Museum is placed here with some reserve, as it has, at the end of the 

 rostrum, two small teeth. The specimen was taken by the Fish 

 Hawk in the Gulf Stream off Cape Florida, one mile E. 3^ N. of 

 Fowey Rocks Light, 50 fathoms, fine gray sand, coral, temp. 69° F., 

 March 30, 1903, station 7516 (Cat. No. 46984). It has not been 

 compared with the holotype. 



Remarks. — For occasional bifurcation of an entire rostrum see 

 under C. rostratus and tenuirostris. 



COLLODES NUDUS Stimpson 



Collodes Jiiidus Stimpson, Bull. Mus. Comp. Zool., vol. 2, 1871, p. 120 

 (type-locality, off Carysfort Reef, 40 fathoms; holotype not extant). — 

 A. Milne Edwards, Crust. R6g. Mex., 1878, p. 178. 



Diagnosis. — Carapace and feet naked. Dactyli of ambulatories 

 spinous on inner edge. 



Description (after Stimpson) . — Allied to C. granosus and C. trispi- 

 nosus, having three spines on the dorsum similar in shape and posi- 

 tion to the spines of those species. C. nudus differs, however, in its 

 naked carapace and feet and in the less numerous and prominent 

 granulated tubercles on the dorsal surface. The carapace is also 

 much broader anteriorly. The ambulatory legs of the second pair 

 are rather longer than those of the first pair; dactyli of the legs 

 armed with spines along the inner edge. 



Measurements. — Male, holotype, length of carapace 0.24 inch 

 (6 mm.), width 0.18 inch (4.6 mm.), length of first ambulatory leg 

 0.45 inch (11.4 mm.). 



Range. — Known only from the type male from off Carysfort Reef, 

 Florida, lat. 25° 13' 40" N.; long. 80° 10' 45" W.; 40 fathoms; sand; 

 March 21, 1869; station 7, U. S. Coast Survey steamer Bihh.
