a broad basal part and 2 small uniarticulate rami. Maxillae with the exopodal 

 and epipodal lobes distinctly defined. Anterior maxillipeds with 2 setiferous lobes 

 inside the claw-bearing joint. Posterior maxillipeds moderately strong and of usual 

 structure. 1st pair of legs somewhat resembling those in Laaphonte, but less 

 strongly built, outer ramus very small, 3-articulate, and abruptly bent at the base, 

 inner ramus biarticulate and distinctly prehensile, proximal joint long and slender 

 with a well-developed seta inside at some distance from the end, distal joint in 

 curved and armed at the tip with a slender claw and a still more slender seta, 

 its outer edge carrying moreover a small bristle. Natatory legs with the inner 

 ramus more fully developed than in Laophonte, though consisting of only 2 joints, 

 the proximal one somewhat expanded, the distal one narrow, with 5 or 6 slender 

 seta?. None of these legs are transformed in male. Last pair of legs with the 

 distal joint long and narrow, proximal joint narrowly produced inside; those in 

 male, as usual, much smaller than those in female. 



Remarks. Though the systematic position of this genus appears somewhat 

 doubtful, I think that it should more properly be placed in the family Laophontidfy 

 with which it agrees both in the external appearance of the body and in most of the 

 anatomical details. The most conspicuous difference is found in the structure of 

 the mandibular palp, which, unlike that in the other genera, is distinctly biramous. 

 The separation of the rostral plate from the cephalic segment by a transversal 

 suture, and the presence of a ciliated seta inside the proximal joint of the inner 

 ramus in the 1st pair of legs, are both characters which it shares with another 

 genus evidently belonging to the present family, viz., Laophontopsis. The for 

 recorded by Th. Scott as Normanella attenuata cannot by any means be referre 

 to the present genus. In addition to the type species, 2 new, nearly-allied species 

 will be described below.

Specific Characters. Female. Body sub-cylindrical in shape, though not 

 very slender, and slightly constricted in the middle. Cephalic segment about the 

 length of the 3 succeeding segments combined, and somewhat contracted in front, 

 rostral plate triangular, with the tip obtusely acuminate. Urosome nearly as long
