122. Laophonte applanata, G. O. Sars, n. sp. 
(Pl. XI). 
Specific Characters, — Female. Body very broad and flat- 
tened, 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 distincl 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. Epimeral parts of the 3 suc- 
ceeding segments rounded off and fringed with a dense row of spinules. 
Last pedigerous segment somewhat less broad than the 3 preceding 
segments. Urosome much shorter than the anterior division, lateral 
expansions of the anterior segments linguiform and slightly recurved, 
being, like those of the anterior division, densely fringed with spinules; 
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 antenne 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 antenne rather strongly built, with the spines of the 
distal joint very coarse, claw-like, outer ramus uniarticulate, with 4 rather 
thick sete. Oral parts exhibiting the structure characteristic of the 
genus. Posterior maxillipeds large and powerful. st pair of legs like- 
wise greatly developed, with the inner ramus very strong, biarticulate, 
last joint tipped with a powerful claw; outer ramus, as usual, very 
narrow, triarticulate, 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 the 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 sete 5 in number, one of them issuing 
from the inner edge near the tip; inner expansion ‘of proximal joint 
very small and narrow, with only 3 sete. Ovisac of moderate size, 
rounded oval in form. 
Male, as usual, smaller than female, and having the anterior an- 
tenn strongly hinged, sub-cheliform. Inner ramus of 3rd pair of legs 
transformed in the usual manner, being distinctly triarticulate, with the
