34 JAMES A. GRIEG. [SEC. ARCT. EXP. FRAM 



which BERGH has described in his work: "On the nudi-branchiate gaste- 

 ropod Mollusca of the North Pacifik Ocean, with special reference to 

 those of Alaska" (p. 89, tab. 1, fig. 1820, tab. 3, fig. 712). How- 

 ever, as has been already pointed out by POSSELT in "Gronlands Bra- 

 chiopoder og Bloddyr" the median tooth of dendronotus frondosus 

 varies greatly both in form and denticulation. It can be short and 

 broad with a slight denticulation as in this specimen, or the cutting 

 edge may even be quite smooth (the variety dalli) or again it may be 

 high and narrow and have numerous margial teeth. The lateral teeth 

 too may vary in form and denticulation. 



Dendronotus frondosus is to be found as far north as Upernivik 

 on the west coast of Greenland. On the east coast of America it is 

 met with from Cape God to Labrador, and it is further known to occur 

 in the Bering Sea and Bering Strait. On the other hand it has not 

 previously been mentioned as occurring in the archipelago north of 

 America. For further particulars regarding the distribution of dendro- 

 notas frondosus I would refer to ODHNER: "Opistobranchia and Ptero- 

 poda", where a very full account is given of the distribution of this 

 species. 



Coryphella salmonacea, COUTHOUY. 



Locality: 



Aug. 16. 1898. Reindeer Point, Foulke Fiord, 8 m. 

 July 9. 1901. Renbugten. 



There are in all six specimens of this species, one being from 

 Foulke Fiord. This and the two specimens from Renbugten were care- 

 fully examined and were found to be typical coryphella salmonacea. 

 The specimens from Renbugten have a length of 15 20 mm. The 

 one from Foulke Fiord is about 25 mm. 



NARES found this species at Discovery Bay, Grant Land (SMITH).
