ADDITIONS AND CORRECTIONS. 



Mytilus adriaticus var. ovalis Sowb. — Thrown up in Pentle 

 Bay. Rare. 



Rissoa vitrea Mont. — This is an error. The specimens are 

 proxiina Alder. 



R. semistriata Mont. — From the Menavawr dredgings. This 

 occurs in Mr. Jenkinson's Ust (p. 302) and is thus, as well 

 as lanthina exigtia, mentioned below, confirmed. 



Aclis supranitida S. Wood. — One specimen in good con- 

 dition from the Menavawr dredging. 



Odostomia scalaris Phil. — -The type occurs besides the var. 

 riifescens in the Menavawr shell sand. 



Natica montacuti Forbes. — Three or four living specimens ; 

 Menavawr. 



lanthina exigua Lam. — Once thrown up on the Western 

 beaches about seventeen years ago. They occurred in 

 large numbers with lanthina rotnndata Leach, the latter of 

 unusual size ; the beaches are described as being blue 

 with them. 



Fusus gracilis DaCosta. — Mr. H. K. Jordan regards these 

 specimens (two worn shells) as undoubtedly F.Jejfreysianus 

 Fischer. He also confirms our view of the variety men- 

 tioned as being certainly convoluta. 



Pleurotoma attenuata Mont. — One specimen with PL 

 nebula from Crow Sound.
