238 Messrs. T. and A. Scott on some 



joint from wliich it s])rings. The first three pairs of thoracic 

 feet are nearly as in Diosaccus tenuicorm's, 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 setce ; secondary joint broadly ovate, extending con- 

 siderably beyond the basal joint and bearing six setse — 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.

 Head, 130 fathoms. 



Three specimens only were obtained, all females. 



Remarhs. This species closely resembles Diosaccus tenui- 

 cornis (Claus), but the anterior and posterior antennse 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. 



Laoplionte littovale^ sp. n. (PI. XI. figs. 7-14.) 



Length '85 millim. (yV of an inch). Body elongate, sub- 

 cylindrical, forehead slightly produced and bluntly rounded. 

 Anterior antennae 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 —

In the male anterior antennse 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 antennse is rudimentary, and con- 

 sists of one small joint bearing an apical seta. The 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
