Habitat. — Abundant between tide-marks at Lochmaddy, Nortb Uist, and also dredged 

 on a sandy bottom in the Laminarian region. On a sandy bottom at Paible, North Uist, 

 in four to five fathoms. In the sandy mud of the bathing pond at the Step-Rock, St. 

 Andrews. Dredged in four to five fathoms and also in fifty fathoms off Balta, July, 1867 

 (J. Gr. Jeffreys). Common in Herm, in sand between tide-marks, August, 1868, and in a 

 similar region in Cobo Bay, Guernsey. Off Symbister Harbour, Whalsey, Shetland, 

 in three to five fathoms, July, 1871. Fragment from Malahide, Co. Dublin (A. C. 

 Haddon). 



Extends to Finmark (A. M. N.); Baltic (Mau); Nova Zembla (Theel); and to Canada 

 (W. C. M.); Labrador (Moore); Greenland (CErsted) ; and 1100 fathoms in 'Valorous,' 

 1875. Siberian Coast (Wiren). Northern seas generally (Malmgren). 



Head (Plate LXV, fig. 4) forms an acutely pointed cone without rings or subdivisions, 

 though when actively thrust amongst the surrounding structures it frequently presents 

 crenations at the edges. In some, four deep-seated dark specks occur in front of the 

 mouth arranged in a crescent, the posterior pair being nearest each other. In others there 

 is less definition, the dark specks (often two) being irregular. It is doubtful if these are eyes.
