1898-1902. No. 20.] BRAGHIOPQDS AND MOLLUSCS. 27 



Bela harpularia has not previously been found in waters north of 

 America. On the west coast of Greenland its northernmost limit is 

 Riten Bank, Disco Bay (POSSELT). 



Trichotropis conica, MOLLER. 



Locality: 



July 22. 1900. The winter harbour, Havnefjord, about 60 m. Small stones. A 

 specimen 13.5 mm. high, which closely resembles the illustration 

 of this species given by G. 0. SARS. 



Trichotropis conica has not previously been found in waters north 

 of America. It was known, however, to occur in the Barents Sea, the 

 northern coasts of Norway, Jan May en, the east and west coasts of 

 Greenland -- the northerly limit being Egedesminde -- and Gape Sable, 

 Nova Scotia. 



Trichotropis borealis, BRODERIP & SOWERBY. 



Locality: 



Aug. 26. 1898. Bay near Rice Strait. 

 Aug. 28. 



July 22. 1899. The winter harbour, Havnefjord, 16 m. 



July 22 1900. , about 60 m. Small stones. 



Aug. 1. Off the entrance to Stordalen. Havnefjord, 1050 m. Small stones. 

 Aug. 30. 1901. The head of the Gaasefjord, 8 m. Clay with small stones and 

 fucaceae. 



The specimens, which have a height of 13.5 19 mm. most closely 

 resemble in form the specimen from the Kara Sea depicted by COLLTN, 

 but have a less slender tip. Moreover they have fewer setiferous spiral 

 carinae, some specimens being actually quite without setae. The number 

 of spiral carinae on the last whorl varies greatly. The lowest number 

 is five, of which three are setiferous. The largest number of setiferous 

 spiral carinae is four, whereas in COLLIN'S specimen there were five. 

 Those specimens which are without setae have ^comparatively broader, 

 more numereus and less prominent spiral carinae. They may be refer- 

 red to the variety inermis, HINDS which was found by Nares at Dis- 

 covery Bay and Dumbell Harbour, Grinnell Land (SMITH). The speci- 

 mens from the Fram Expedition are rather larger than the biggest 

 specimens of this species hitherto known. 



To the variety acuminata, JEFFREYS must be referred an empty 

 shell 10.5 mm. long, which differed from the rest in having a more 

 slender form and its last whorl less ventricose.
