rudimentary. Mandibles with the cutting edge armed outside with a prominent 

 tooth cleft at the tip, its inner part forming an undivided plate ; palp compara- 

 tively small, but distinctly biramous. Maxillae with the epipoclal and exopodal 

 lobes imperfectly developed. Anterior maxillipeds with 2 well-developed setiferous 

 lobes, and a rudiment of a 3rd inside the claw-bearing joint. Posterior maxillipeds 

 rather large, with the dactylus long and slender. 1st pair of legs with the inner 

 ramus biarticulate and shorter than the outer. Inner ramus of the 3 succeeding 

 pairs distinctly 3-articulate, but much smaller than the outer. Last pair of legs 

 with the distal joint well defined and oblong in form; inner expansion of prox- 

 imal joint obsolete. 



Remarks. This and the succeeding genus should perhaps more properly 

 have been referred to the Cletodidce, with which they agree both in general 

 appearance and in the structure of most of the appendages. Yet they both differ 

 very materially in the much fuller development of the inner ramus of the natatory 

 legs, this ramus not being rudimentary, as in the Cletodidce, but distinctly 

 3-articulate, like the outer. In the present genus, however, this ramus in the 

 1st pair of legs is composed of only 2 joints, as is also the case in several other 

 genera of the present family. The genus comprises as yet only a single species, 

 to be described below.

Specific Characters. Female. Body moderately slender, with the anterior 

 division somewhat depressed and wider than the posterior. Cephalic segment 

 rather large and slightly contracted in front; rostral projection extremely small. 

 Urosome about the length of the anterior division and cylindric in form, all the 

 segments densely fringed behind with slender spinules; last segment about as 

 large as the 2 preceding ones combined, and provided below in the middle with 

 a transverse row of spinules, anal opercle semilunar, smooth. Caudal rami longer 

 than they are broad, sub-quadrangular in form and somewhat divergent, inner 

 medial seta exceeding half the length of the body. Eye inconspicuous. Anterior 

 antennae attaining the length of the cephalic segment, 2nd joint the largest, 

 terminal part about the length of the 3 preceding joints combined. Posterior 

 antennae with the distal joint shorter than the proximal one, outer ramus replaced 

 by a simple seta. Posterior maxillipeds rather strong, hand oblong in form, with 

 the inner edge straight, the outer angularly bent in the middle, dactylus exceeding
