172 CATALOGUE OF THE MOLLUSCA 
attached excepting by a bissus. In this state we take it to be 
the Pecten spinosus 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 Lovén, 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. ? Lima sulculus, Lovén Index Moll. Scand. 32. 
A single valve was dredged by Mr. R. Howse off Whitburn, 
agreeing with a specimen of Z. sulculus we have received from 
Professor Lovén. It is rather more slender, and has the ribs 
stronger than the usual form of LZ. swhawriculata, Mont., but we 
are not sufficiently acquainted with the latter to decide concern- 
ing their specific distinction.

Mr. Embleton informs us that he got this from a number of 
Artemis exoleta and Tellina crassa brought from deep water by 
* Pecten nebulosus, Brown, mentioned in our prefatory remarks as not un- 
ommon in the west of Scotland, may be a variety of this.
