Alvania elegans, Angas, P.Z.S., 1877, t ,f. (non A. 
Adams, 1851, non. Brusina, 1869). 
Suter has identified the New Zealand and Tasmanian shells, 
despite certain descrepancies in the two diagnoses. This step is 
substantiated by his re-description of Hutton’s species based on 
New Zealand specimens, and gives priority to Hutton’s name. 
The insufficiency of the original diagnosis has been rendered 
further unstable by the author’s uncertainty as to the generic 
location of his species, thus at first regarded as a Rissoia, it was 
transferred to Rissoina in 1880 and to Hglista in 1885. Under 
these circumstances I would press the rigid exercise of the rule 
of priority to preserve Tenison-Woods’s name (Angas’ name has 
been in prior use by at least two authors) and this is afforded by 
the fact that Deshayes in 1838 (¢este Schwartz) described a 
Rissoa plicata. 
Tenison-Woods and Angas placed their species in Alvania. I 
agree with Tryon and Suter in quoting the species under Alvinia, 
a section later erected by Montserrato in 1884.
