DECAPOD CRUSTACEANS OP THE BEAUFORT, N. C, REGION. 419 



Family HOMOLIDAE. 



Dromiacea having the eyes incompletely sheltered by orbits when retracted, the 

 sternum of the female without longitudinal grooves, the first article of the eyestalk not 

 much longer than the second, and the gills 13 or 14 on each side. 



There are 4 genera, of which i occurs in the Beaufort region. 



Genus HOMOLA Leach.

Cancer barbalus Fabricius. 1793. t. n. p. 460; Herbst, 1796, vol. n, pi. xxxvn. fig. 6. 

 Homola barbata Wbite, 1847, p. 55; Smith, 1886, p. 637 (.33), pi. n, fig. i. 



Carapace about one-fourth longer than wide, its surface everywhere granulate and spinulose and 

 sparsely setose; the sides straight, only slightly convergent posteriorly and extending almost vertically 

 downward from a spiny ridge that extends backward from behind the strong anterolateral spine. Ros- 

 trum small, bifurcate at tip. A spine on each side at the base of the rostrum, one at the outer orbital 

 angle, a transverse row of two behind the rostrum, behind these a transverse row of eight, and, a little 

 farther back, a small median spine. Anterolateral parts, below and behind orbits, with small spines. 



Eyestalks long, slender at base, and suddenly enlarged below the cornea. Chelipeds of moderate 

 size, their surface granulate and hairy, and the meros and carpus with rows of spines. Walking legs 

 with flattened articles, long, hairy, and spinulose along margins. First segment of abdomen with a 

 prominent median tubercle. 



Length of a female: i6 mm.; width, 12.5 mm. 



One specimen, a female, was collected by the Fish Hawk at station 7334, depth 63 fathoms. 



Family L ATREILLIDAE . 



Dromiacea having the eyes completely exposed on long stalks in which the first 

 article is much longer than the second, the sternum of the female without longitudinal 

 grooves and the gills 8 on each side. 



Of the 2 genera, i occurs in the Beaufort region. 



Genus LATREILLIA Rouz. 



LaireiUia Roux, 1828, p. (i). 



Latieillia elegans Roux. PI. xxxi, fig. 4. 



LaireiUia elegans Roux, 1828, pt. s, pl. xxn; Milne-Edwards, 1834-1S40, 1. 1, p. 277; Smith, 1884, p. 351. [7I, pi. n, fig.j-ia 

 pi. m, fig. I. 



Body pyriform, finely granulate, truncate in front and armed with two long, divergent horns between 

 which a minute spinelike rostrum projects obliquely downward; each horn is minutely spinulose near 

 the tip and at about the proximal third bears a spine on the lower side. Front margin of carapace with 

 an acute spine projecting downward at the base of the eyestalks. Abdomen of the female broad; the 

 first segment with a median tubercle; second segment with a strong median spine; third segment, with 

 which the segments which follow are coalesced, with a stout spine on each lateral margin. In the male 

 the abdomen appears to be composed of six distinct segments and lacks all the spines, except the one 

 of the second segment. 



Eyes large, pyriform, at the end of slender stalks whose length slightly exceeds that of the supra- 

 orbital horns. Third maxillipeds slender and somewhat pediform. Legs very long, almost filiform, 

 their ischial and propodal articles spinulose. Chelipeds about twice as long as the body and about half 

 as long as third walking legs, very slender; hand a little longer than the carpus; movable finger a little 

 less than half as long as the palm. 



Measurements of a female: Length, along median line, 9 mm. ; width, 5.5 mm. ; horn, 5 mm. ; third 

 leg, 67 mm.
