78 CATALOGUE OF THE MOLLUSCA 



attached excepting by a bissus. In this state we take it to be 

 the Pecten sjnnosus of Capt. Brown, which he says he " first 

 found on the Herd Sands at South Shields. 



A specimen of Pecten septemradiatus, Miill.,* was presented 

 to the Newcastle Museum by the Rev. Josh. Law, who thinks he 

 obtained it from the fishermen at Sunderland, and that it was 

 probably got off our coast. It is similar to Swedish specimens 

 sent to us by Professor Loven, and we have also seen a similar 

 variety from the west of Scotland. There is therefore no impro- 

 bability of its occurring here, but the present instance is scarcely 

 sufficient to warrant its admission.

Var. 1 Lima sulculus, Loven Index Moll. Scand. 32. 

 A single valve was dredged by Mr, R. Howse off Whitburn, 

 agreeing with a specimen of L, sulculus we have received from 

 Professor Loven. It is rather more slender, and has the ribs 

 stronger than the usual form of L. subauriculata, Mont., but we 

 are not sufficiently acquainted with the latter to decide concern- 

 ing their specific distinction. 



Sub-order. Dimyaria, Lamarck.

Mr. Embleton informs us that he got this from a number of 

 Artemis exohta and Ttllina cra^sa brought from deep water by 



• Pecten vcbulosus. Brown, oieutioued in our prefatory remarks as not uu- 

 mmon in the west of Scotland, may be a variety of this.
