POLYCH.ETA OF THE L.M.B.C. DISTRICT. 147 



Family. — NEPHTHYDiE. 



* Nep htlujs cccca , (F abr . ) . 



Hab : " Hyjpna " and " Despatcb " expeditions, 1886. 



In this district much less common than N. liomhergi. 

 Its range is also more restricted than the latter, having 

 been taken only by the dredge. 



Nephthijs liomhergi, kxx^. and M. Edw. 

 Hab : S, E, NB, L, 8, 6, 10, 13, ''Despatch" exped., 1880. 



The characteristic Nephthijs of the Irish Sea, common 

 along the N. Welsh, English and Scottish coasts bordering 

 this basin, wherever sand occurs. Together with this 

 constancy on all our shores it posesses a wide bathymet- 

 rical range, having been taken frequently with the dredge 

 at varying depths. Thecate Infusoria are frequently met 

 with parasitic upon the bristles. This is the N. assimilis 

 of Malmgren and A^. lougisetosa of Oersted.

 Hab : Puffin Island ; 5 fathoms. 



* Glycera cluhia, Blainville. 



I have several times found traces of a large species 

 — referred provisionally to G. dithia — within the stomachs 

 of Cod. The length would be nearly six inches and the 

 four stout black teeth present within each were of corres- 

 ponding size.
