>.- This is the form originally recorded by Boeck as the type of 

 his genus Danielssenia. The .///< s/Y//^ x/////^/W< is unquestionably identical with 

 Boeck's species. 



Occurrence. I have met with this 1'onn occasionally in several places on 



the Norwegian coa>t up to the Lofoten Klaiids. and Th. Scott also records it from 

 Kast Finmark. It occurs in depths ranging trom 12 to 30 fathoms, muddy bottom.

>/ r///Y {'litiytirtrr*. /^'in/tlr. Very like the preceding species, but of much 

 larger size and somewhat more slender form of body. Anterior antennas 

 distinctly 5-articulate, the terminal part being divided into 2 well-defined joints. 

 Posterior antennae scarcely cli tiering in structure from those in the type species. 

 Posterior maxillipeds with the hand coarsely ciliated inside, one of the setae 

 i-siiinu r from the basal joint very strong and coarsely ciliated. Natatory legs 

 differing only very little in structure from those in the type species, though on 

 the whole more strongly built. Last pair of legs likewise of a very similar 

 -hape and armature, inner expansion of proximal joint, however, comparatively 

 larger and more rounded at the extremity. 



Mult- with the anterior antenna' comparatively more strongly built than 

 in / >. I/////I-/I. Inner ramus of 2nd pair of legs transformed in a manner very 

 similar to that in the type species, the mucroniform process, however, being 

 comparatively shorter and stouter. 



Colour about as in the preceding species. 



Length of adult female o '.to mm. 



li'i-miii'lcs --The present form is very closely allied to the preceding species, 

 and it is rather difficult t< derive from the structural details a sufficient number 

 of good distinctive chara. hut th<- difference in si/e is so pronounced that this 



alone must prove the present form to be specifically distinct, the more so as 

 both species in some cases are found living together in the very same places 

 and mid'-r allo'_"'ther similar conditions. 



Occurrence. I have found this form in considerable abundance in one 

 locality, at Skutesna-s. in a depth of about 12 fathoms, muddy bottom. It also oc- 

 curs occasionally in other place- on the west coast of Noruav.
