12:2. Laophonte applanata, G. 0. SARS, n. sp. 



(PI. XI). 



Specific Characters. Female. Body very broad and tlat- 

 ti-ned. with all the segments, except the last, lamellarly expanded late- 

 rally. (Cephalic segment large and broad, exhibiting on each side, at 

 about the middle, a distinct notch, edge of the segment finely ciliated; 

 rostral projection horizontally produced, and of a rather peculiar appea- 

 rance, being spatulate in form and terminating in 2 broadly rounded 

 lobes densely clothed with fine hairs. Kpimeral parts of the 3 suc- 

 ceeding segments rounded off and fringed with a dense row of spinnles. 

 Last pedigerous segment somewhat less broad than the 3 preceding 

 segments. Urosome much shorter than the anterior division, lateral 

 expansions of the anterior segments lingniform and slightly recurved, 

 being, like those of the anterior division, densely fringed with spinnles; 

 last segment sub-quadrangular in shape, with the anal opercle smooth. 

 Caudal rami somewhat far apart and scarcely twice as long as they are 

 broad, both edges minutely spinulose, tip transversely truncated, with 

 the inner medial seta rather slender and elongated, outer comparatively 

 short. Anterior antennas of moderate length and composed of 7 articu- 

 lations, 2nd joint without any projection behind and much shorter than 

 the 3rd, 4th joint still shorter, terminal part about the length of the 3rd 

 joint. Posterior antennae rather strongly built, with the spines of the 

 distal joint very coarse, claw-like, outer ram us uniarticulate, with 4 rather 

 thick setae. Oral parts exhibiting the structure characteristic of the 

 genus. Posterior maxillipeds large and powerful. 1st pair of legs like- 

 wise greatly developed, witli the inner ramus very strong, biarticulate, 

 last joint tipped with a powerful claw; outer ramns, as usual, very 

 narrow, Inarticulate, and extending somewhat beyond the middle of the 

 proximal joint of the inner. Natatory legs with the rami slender and 

 built upon the type characteristic of Ihe genus. Last pair of legs resem- 

 bling in structure those in L. depressa, the distal joint being conside- 

 rably produced, and tapering to a conical point carrying a very slender 

 hair-like bristle, marginal setae 5 in number, one of them issuing 

 liom the inner edge near the tip: inner expansion of proximal joint 

 very small and narrow, with only 3 setae. Ovisac of moderate size, 

 rounded oval in form. 



Male, as usual, smaller than female, and having the anterior an- 

 ti-iin.-i- Mi-ongly hinged, sub-cheliform. Inner ramus of 3rd pair of legs 

 transformed in the usual manner, being distinctly Inarticulate, with the
