238 Messrs. T’. and A. Scott on some 
joint from which it springs. The first three pairs of thoracic 
feet are nearly as in Diosaccus tenuicornis, except that a stout 
plumose seta springs from the basal joint of the first pair, 
and the outer branches of the same pair are fully half the 
length of the entire inner branches exclusive of the terminal 
claws (fig. 4). Inner branches of the fourth pair two-jointed, 
slender, and shorter than the outer branches. Basal joint of 
the fifth pair subquadrate and furnished with four subterminal 
plumose sete; secondary joint broadly ovate, extending con- 
siderably beyond the basal joint and bearing six sete—two 
small ones at the apex, one plumose seta of moderate length 
on each side of the apex, and two small ones on the outer 
margin (fig. 6). Caudal stylets as long as the last abdo- 
minal segment. Ovisacs two. 
Hab. Moray Firth, a few miles northward of Kinnaird 
Head, 130 fathoms. 
Three specimens only were obtained, all females. 
Remarks. 'This species closely resembles Diosaccus tenui- 
cornis (Claus), but the anterior and posterior antenne are 
shorter and stouter, the outer branches of the first thoracic 
feet are proportionally longer, the inner branches of the fourth 
pair are only two-jointed, and the secondary joints of the fifth 
pair are ovate and extend considerably beyond the basal 
joints. 
Laophonte littorale, sp.n. (Pl. XI. figs. 7-14.) 
Length 85 millim. (;'5 of an inch). Body elongate, sub- 
cylindrical, forehead slightly produced and bluntly rounded. 
Anterior antenne sparingly setiferous—in the female seven- 
jointed, the third joint longer than any of the others, while 
the fifth is very short, as shown by the formula— 
Female anterior antenne. . 
In the male anterior antenne the fourth joint from the end is 
considerably dilated, the following joint is distinctly hinged 
to the fourth; the penultimate joint is very short, and the 
last forms a stout grasping claw. The secondary branch of 
the three-jointed posterior antenne is rudimentary, and con- 
sists of one small joint bearing an apical seta. ‘I'he mouth- 
organs are nearly as in Laophonte curticauda, Boeck. The 
outer branches of the first thoracic feet, which consist of three 
subequal joints, are equal to about half the length of the inner 
branches exclusive of the terminal claw. The inner branches
