1898-1902. No. 20.] BRACHIOPODS AND MOLLUSCS. 33 



Most of the specimens may be referred to the form depicted by 

 G. 0. SARS in "Mollusca regionis arcticae Norvegiae" (tab. 24, fig. 8). 

 Two specimens from the head of the Gaasefjord belong to the variety 

 elata FRIELE and one specimen from Renbugten to the variety tumida, 

 G. 0. SARS. This last is 43.5 mm. high and 25.5 mm. broad and its 

 aperture is 26 mm. high and 15 mm. broad. The largest specimen of 

 the variety elata is 70.5 mm. high, 35.5 mm. broad, and its aperture 

 32 mm. high. SARS' form has a height of up to 57 mm. The typical 

 form described by HANCOCK and more fully by PFEFFER afterwards has 

 a height of up to 60 mm. 



Buccinum ciliatum, FABRICIUS. 



Locality: 



Sept. 19. 1900. Off Forvisningsdalen, Gaasefjord, 440 m. Clay with small 

 stones. 



One specimen 18 mm. high belonging to the variety laevior, MORCH. 

 Littorina rudis f. gronlandica, MENKE. 



Locality: 

 July 29. 1898. Egedesminde. Very common. 



Dendronotus frondosus, ASCANIUS. 



Locality: 



Aug. 5. 1898. Upernivik, 6 m. 



Aug. 24. Rice Strait. 



July 22. 1900. Winter harbour, Havnefjord, about 60 m. Small stones. 



July 31. Round Vestre Sund, Havnefjord, 20-60 m. 



June 29. 1901. Off the camping ground, Jammerbugten. 



July 17. The entrance to Gaasefjord. 



Aug. 30. The head of the Gaasefjord, 8 m. Clay with small stones. 



There are in all 9 specimens of this species, of which one is from 

 Upernivik and two are from Rice Strait. The remainder are from 

 Jones Sound. 



The specimens, which have a length of 17 42 mm., are not in a 

 good state of preservation. Judging from the material preserved in 

 alcohol the colour seems to have varied from pure white to a reddish 

 brown. In the largest specimen from Havnefjord the radula consists of 

 41 rows with 12 14 lateral teeth on either side. Median tooth is com- 

 paratively short and broad, with a fine denticulation along the margin. 

 Denticulation does not, however, quite extend to the tip of the tooth. 

 In this respect the specimen closely resembles dendronotus purpureus
