300 CHASTER AND HEATHCOTE : MOLLUSCA OF OBAN. 



above, part of the nucleus of the shell is seen coiling down- 

 wards. Our specimens from Guernsey and Puffin Island, 

 near Anglesea, exhibit the same peculiar features. 



** O. minima, Jeffreys. Several living and dead specimens 

 of this minute and rare species were found in the dredgings. 

 We here take the opportunity of noting that it has occurred 

 to us at Rothesay, Isle of Man, and Puffin Island. 

 Probably a careful search will show that it is distributed 

 over the whole west coast of Scotland and England, as far 

 south, at least, as the last named locality. 



Auriculina insculpta, Mont. {Odostomiainsculpta). [A.M.N.]. 

 Living and dead in the dredgings, all the specimens being 

 small. Scarce in Clyde district (Brown). 



** Eullmella scillae, Scacchi. {Odostomia scilla). A fine live 

 specimen, measuring lo mm., dredged off Fraoich Island. 



E. acicula, Phil. \_EtiIimeUa affinis, A.M.N.]. A dead ex- 

 ample dredged off Lismore. Of the var. ventricosa, Forbes 

 several were dredged alive and dead. These are remarkably 

 thin, and present none of the microscopic spiral lineation 

 exhibited by the type, the nucleus also being more nearly 

 planospiral. As our knowledge is insufficient we prefer to 

 retain the varietal position for this form at present. Rare 

 in the Clyde district (Brown). 



*"^" E. nlTldissima, Mont. A live specimen of this delicate 

 little species was found in the dredgings. Mr. Robertson 

 has taken it in the Clyde district (Brown). 



Phasianella pullus, L. [Jeffreys; A.M.N.]. Dredged alive 

 in shallow water near the basaltic cliff south of Oban. 

 Apparently rare or very local. 



Cyclostrema nitens, Phil. [A.M.N.]. Common in many 

 of the dredgings. We can find no mention made of the 

 two shallow sinuations which are present in the outer lip, 

 one just above, and the other below, the periphery. 

 This character has been noticed in all the specimens, from 

 many localities, which have been examined.
