MR. E. J. MTERS'S llEYISION OF TUE HIPPIDEA. 883 



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

 little thickened below the middle, the minute eye being situated 

 on the inferior surface near the extremity. Antennules slender, 

 with flagella more than five times as long as the carapace. Eeet 

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

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

 more slender. 



Hah. St. Thomas (Stim^son). I have seen no specimens of 

 this species.

 (1862). 



Carapace witb the same markings on the surface as in Z. 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, rather 

 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. 



Hah. 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- 

 lated in the middle. Antennules and antenna; rather long, and with 

 a multiarticulate flagellum ; antenna; without an accessory joint.
