G. 0. SARS. [SEC. ARC. EXP. FRAM 



Fam. Campylaspidse. 

 11. Campylaspis carinata, HANSEN. 



A solitary female specimen of this peculiar form, described by Dr. 

 HANSEN from Disco Island, was found on Sept. 19, 1900, outside the 

 Forvisnings Valley. 



Order Isopoda. 

 Suborder Chelifera. 



Fam. Tanaidse. 



12. Heterotanais h'micola (HARGER). 



Some specimens of this form, also recorded by Dr. HANSEN from 

 the coast of Greenland, were picked up from the bottom-residue of 3 

 of the bottles. 



13. Leptognathia longiremis (LILLJEB.). 



A single specimen, apparently belonging to this species, occurred 

 in a bottle with collections taken on July 18, 1901, from the mouth 

 of Gaase Fjord. 



14. Cryptocope arctica, HANSEN. 



Three specimens of this distinct species, first described by Dr. 

 HANSEN from Novaja Sembla, were found in the same bottle as the 

 preceding species. 



Suborder Valvifera. 



Fam. Arcturidse. 

 15. Arcturus baffini, SAB. 



This characteristic arctic form was taken in no less than 12 dif- 

 ferent places. Among the specimens there are some in which the 

 dorsal spines are much reduced in size, thus apparently forming a 

 transition to the form recorded by the present author under the name 

 of A. tuber osus.
