differing, 1st joint of inner ramus in the L'nd and 3rd pairs exhibiting an appear- 

 ance similar to that in Certnnia, the inner corner being vreatly produced, and 

 the natatory seta transformed in to a -troni: spine. Last pair of legs with the 

 distal joint comparatively less -lender than in ('. <-liirirnti*. middle apical seta 

 quite short.

/.'<-//"//.>. Though very closely allied to the preceding species, this form 

 is unquestionably specifically distinct, diftering not only in the greater length of 

 the caudal rami. hut also in the smaller si/e of the lateral projections of the 

 nenital segment, and partly also in the structure of the legs. 



Occurrence. < >nly 2 female specimens of this form have hitherto come 

 under my notice. They were taken from great depths oil the west coasl of Nor- 

 , the exact locality not being stated. 



Gen. 7. Eueanuella, Scott, 1901. 



Generic Cli'inn-trr*. General form of body about as in Cerviniopsis. 

 Cephalosome imperfectly defined from the 1st segment of metasome, and projecting 

 in front to a conically-pointed rostrum. Epimeral plates of the 3 succeeding 

 segments well developed, acutely pointed behind. Genital segment in female with 

 a well-marked transversal suture in the middle dorsally, and produced on each 

 side to a -tmng spiniform projection. Caudal rami somewhat lamellar, noncon- 

 tiguous. taperiim distally. Anterior antenna- distinctly 7-articulate. and edged with 

 ciliated seta\ one of them, issuing from the 4th joint, being much larger than the 

 others, the 3 outer joints abruptly much narrower than the preceding ones. 

 Posterior antenna' comparatively feeble] in structure than in the 'J preceding 

 genera, outer ramus well developed, (-articulate. Oral parts on the \\liole re-

referred to the I'amiU Cerviniidce, as here defined, [n several respects it exhibits, 



indeed, a close resemblance to the genus ( 'i IT, ///r/y/.s/.s-, hut differs in some other
