A single living specimen, which Mr. W. H. Dall has identified as 



this species, was taken by the Albatross, at station 2035, off Martha's 

 Vineyard, in 1362 fathoms. When first taken it was supposed to 

 belong to W. tenera Jeffreys. No authentic instance of the occur- 

 rence of this species on the N. American coast has been recorded. 

 On the coast of Europe it is not uncommon in 30 to 700 fathoms, 

 and ranges from Norway to France. It has also been recorded from 

 Greenland, Northern Asia and Japan. 



The following two species have not yet been taken south of Labra- 

 dor, but may be regarded as belonging to tlie North American fauna. 



Waldheimia tenera (Jeffreys). 



Terehratula feraera Jeffreys, Ann. Mag. Nat. Hist., Sept., 1876, p. 250; Proc. Zool. 

 Soc. London, for 1878, p. 405, pi. 22, fig. 7. 



This species was taken by the Valorous Expedition, far off the 

 coast of Labrador, in 1450 fathoms, N. lat. 56" U', W. long. 37° 41'. 

 It has not yet been recorded from any otlier locality, but is likely to 

 occur off our coast at similar depths.

This species was recorded by JefiVeys, from oil" tlie coast of north- 

 ern Labrador, N. lat. 59° lo', W. long. 50° 25', in 1750 fathoms, and 

 also from N. lat. 56° 11', W. long. 37° 41', in 1450 fathoms. 



On the European coast it has been taken, according to Jeffreys, at 

 several localities, in 650 to 1750 fathoms, and off Marocco and the 

 Azores, in 1192 to 2199 lathoins.
