Remark?. I liave recently had an opportunity, through the kindness of 

 IW. Brady, of examining a of the Challenger specimens, from which the original 

 description of his .Witlcux iinimhis was made, and cannot find any difference' 

 whatever between them and the northern form. For this reason I must consider 

 Brady's and Boeck's species as identical, in spite of the widely-separated localities. 



Occurrence. I found this form last summer not unfrequently at Aale- 

 sund and in the Storfjord, in depths ranging from 30 to 150 fathoms. 



Dirtributwn.---Q the Shetland Islands (Scott), Faroe Channel (Norman's 

 Collection), Indian Ocean, Torres (Strait, Chinese Sea, South Atlantic Ocean (Brady), 

 Gulf of (Juinea (Scott). 



Page 2i. The following new genus is to he :idded: 



, GK 0. Sars. 



It'iicnc Cluintrtrrx. External appearance somewhat resembling that of 

 the front lieing produced below to a strong bifurcate rostrum. Last seg- 

 ment. of metasome, however, well defined from the preceding one, and having the 

 lateral corners acutely produced. Urosome of moderate size, with the caudal rami 

 romparatively short; outermost seta rudimentary, appendicular bristle very small. 

 Anterior antonnce slender and attenuated, consisting (in female) of 24 well-defined 

 articulations. Posterior antenna) and oral parts nearly agreeing in their structure 

 with those in ('hind/us, the posterior maxillipeds exhibiting a similar slender form. 

 Legs likewise built upon the same type as in that genus. 



Itcntiirkx. This new genus is somewhat intermediate in character between 

 .l-.'tiilt'tt* and (!h.iri<lint*. agreeing with the former in the strongly developed, bi- 

 I u mite rostrum, while the structure of the caudal rami and of the several 

 appendages resembles more that of ('hiri'l'ms. The present genus differs from 

 both these genera in the fact that the last segment of the metasome is well defined 

 from the preceding one. The genus comprises as yet only a single species, 

 described below.
