8 G. 0. SARS. [SEC. ARC, EXP. FRAM 
Fam. Campylaspide. 
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. Tanaide. 
12. Heterotanais limicola (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. Arcturide. 
15. Arcturus baffini, Sas. 
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 
transilion to the form recorded by the present author under the name 
of A. tuberosus.
