it agrees very closely with the account given by Burger. 1 ) A 

 slight point of difference lies in the fact that the dorsal musele 

 cross in the hinder nephridial region is more strongly developed 

 th an in his specimens and encloses some longitudinal musele fibres. 



4. Callinera buergeri (Bergendal, 1900). 



Several specimens dredged from Herlø fjord on a muddy bottom 

 in a depth of about 100 metres. From an examination of sections 

 I am able to confirm the full and excellent account given by 

 Bergendal 2 ). I also agree with his more recent view 3 ) as to the 

 nature of the large cells just beneath the basement membrane in 

 the precerebral region, and consider them to be gland cells and not 

 ganglion cells as he had been earlier led to suppose.

5. Eupolia sp.? 



A single specimen of a small Eupolia in a somewhat frag- 

 mented condition was brought up in July 1901 from over 100 metres 

 on a rocky bottom in the Oster fjord. Externally it resembled in 

 its general appearance and markings a small specimen of E. curta. 

 I was however able to determine the absence of eyes in the living 

 state. Consequently it cannot have belongecl to the above species. 

 By the time I was able to preserve it the worm was much frag- 

 mented and macerated, and sections enable me only to establish the 

 genus. It is however inter esting to tind so far north a specimen 

 of a typically tropical and subtropical genus, which has previuosly 

 not been recorded from further north than the south coast of Eng- 

 land. 4 )
