less numerous and are more scattered than those we find in similar- 

 sized specimens of rossia glaucopis. 



OWEN'S specimen was found by Ross in 1832 in Elwin Bay - 

 Prince Regent's Inlet; and rossia palpebrosa has also been found on 

 the west coast of Greenland and at Spitzbergen, the Murman Coast and 

 in the Kara Sea. 



We have numerous eggs of a rossia from the head of the 

 Gaasefjord, 6 40 m., clay with small stones, (Sept. 20, 1900), which 

 probably belong to rossia palpebrosa. These eggs are 10 12 mm. in 

 diameter. Such eggs as were subjected to careful examination did not 

 contain embryons. 



P. S. 



Since this work has gone to press, HANS KLER has issued his trea- 

 tise: "On the Bottom Deposits" (Rep. II Norweg. Arct. Exp. in the Fram 

 18981902 Vol. 3, No. 17, 1909) in which he describes a number of 

 molluscs from Jones Sound. Dr. KLER has been kind enough to place 

 this mollusc-material at my disposal, and on examination it was found 

 to contain two species, cylichna alba and utriculus pertenuis, that were 

 not represented in the collection of molluscs from the Fram Expedition 

 which I had previously examined. There was also a tellina moesta 

 from the entrance to Stordalen, Havnefjord. 



From the Westside of the entrance to Stordalen, Havnefjord, 16 

 20 m. clay, Dr. KLER mentions modiolaria corrugata and area gla- 

 cialis. These species must however be removed again from the list of 

 fauna belonging to Jones Sound: since it was found by closer in- 

 vestigations that the specimens did not belong to those species, but to 

 modiolaria laevigata var. substriata, GRAY, and lyonsia arenosa M0L- 

 LER. Of the last named species only a defective right valve was found. 



Cylichna, alba, BROWN. 



Locality: 

 Sept. 20. 1900. The head of the Gaasefjord, about 30 m. 



A dead specimen, 10.5 mm. long, belonging to the variety 

 corticata (BECH) MOLLER. 



In the archipelago north of America, cylichna alba was 

 previously found at Assistance Bay, Parry Islands and 

 Discovery Bay, Grinnell Land. 



Utriculus pertenuis, MIGHELS. 



Locality: 

 Aug. 8. 1901. The head of the Gaasefjord, 24 m, 



A dead and rather worn specimen, 2.5 m. long, belonging 

 to the typical form. Under the designation of bulla semen, 

 BELCHER, mentions this species from Port Refuge, Parry 

 Islands.
