The greater number of the above species have already been 

 recognised in the tertiary clays of Canada ; * but the following 

 exceptions are deserving of notice. 



Spirorbis vitrea^ has not been named in my previous papers ; 

 but I now find, on comparison with the specimens from Labrador 

 and recent examples from Gaspe, that it is this and not Spirorbis 

 sinistrorsa as previously stated, that occurs in the tertiary beds at 

 Montreal and Quebec. It is at present a deep water species in 

 the Gulf of St. Lawrence and on the banks of Newfoundland. 

 Spirorhis carinata has not previously been observed in the ter- 

 tiary beds ; but is common on the coast of Labrador and Gaspe.f 



Aporrhais occidentalis, the American representative of the 

 ^* Pelican's-foot Spout-shell" of Britain, and remarkable in the 

 adult state for its singularly expanded outer lip, is a deep water 

 shell somewhat widely though not very abundantly distributed 

 on the American coast. I have specimens from Labrador, Sable 

 Island, and Portland, where a very fine living specimen was 

 dredged for me last summer by Mr. Ferrier. 



Saxicava rugosa, occurs in the Labrador collection under the 

 form described as S. Arcticahj Forbes and Hanley. This form 

 is not prevalent though sometimes seen among the Saxicavoe of 

 the St. Lawrence valley deposits, and at present is I think found 

 only in deep water. The intermediate specimens prove it to be 

 merely a variety of the common species. 



Astarte elliptica is the common Astarte of the Gulf of St.
