I remember that man)* years back when I began taking an 

 interest in marine shells I found a small Rissoa in Lyttelton 

 Harbour, which I took for Hutton's R. annulata, misled by the 

 pale band below the suture. Through the kindness of Professor 

 Chilton, Acting Curator of the Canterbury Museum, I have now 

 been able to see the type of Rissoia annulata, which is simply a 

 variety of Rissoina olivacea, Hutton. Everybody who has had 

 to do with these minute shells knows how easy it is to make 

 a mistake if specimens are not actually compared. I am 

 much indebted to the Rev. Mr. Webster for clearing up this 

 error. 



Rissoina (Eatoniella) limbata, Hutton (1883).

 limbata, Webster, Trans. N.Z. Inst., vol. xxxvii, 1905, p. 278, 

 pi. x, figs. 8, 8a (dentit., operc). 



Type, from Auckland, in the Canterbury Museum. 



It is very fortunate that the operculum and dentition of this 

 species were examined by Webster, and the generic position 

 settled beyond a doubt. When I transferred the species to 

 Phasianella I had only a single specimen, obtained near Sumner, 

 which had the operculum deep in the aperture fixed on the 

 animal, and I did not try to extract it. I examined the specimen 

 again and found the operculum white and having a calcareous 

 appearance. The same peculiarity I- observed in Auckland 

 specimens, but on extracting the operculum all the white colour 

 had disappeared, and it was horny, with a claviform process as 

 figured by Webster. There is no doubt that I was misled by the 

 whitish tissue of the animal showing through the semitrans- 

 parent operculum.
