than in L. scutellata. Eye-peduncles large, oval, diverging, and a 

 little thickened below th.e middle, the minute eye being situated 

 on the inferior surface near the extremity. Antennules slender, 

 with flagella more than iive times as long as the carapace. Feet 

 nearly as in L. scutellata ; but the dactylus of the second pair is 

 more sharply excised, and the dactyli of tlie following pairs are 

 more slender. 



Hah. St. Thomas {Stimpson). I have seen no specimens of. 

 this species.

Carapace witb the same markings on the surface as in i» scutel- 

 lata, but stronger. Postfrontal transverse groove broad, with 

 granulated surface. Median lobe of front rounded ; margin armed 

 with small teeth like those of a comb, which become more con- 

 spicuous outwardly as far as the lateral lobes, where the margin, 

 becomes smooth. Eye-peduncles or scales obliquely oblong, ratlier 

 thick, broader behind, antero-lateral angle prominent, subacute ;, 

 inner angle rounded ; eye-specks obsolete in most of the speci- 

 mens, in others barely visible on the inferior side of the ocular 

 plate, near the exterior angle. In other characters this species 

 approaches very near to L. scutellata. 



Sab. Cape St. Lucas {Stimpson, Coll. Brit. Mus.). 



Two specimens (a male and a female) are in the British-Museum 

 collection, from the Smithsonian Institution. The fifth segment, 

 in both sexes has slender lateral lobes or wings. The terminal 

 segment in the male is triangular, broad, and rounded on the sides 

 at its proximal and acute at its distal extremity ; that of the 

 female is ovate-triangular, more rounded and obtuse at its distal 

 extremity. They are both of small size. Length of carapace 

 about 5 lines.

Eye-peduncles very slender, elongated, cylindrical, and articu-

 t multiarticulate flagellum ; antennae without an accessory joint.
