Mr. Dall observes, " If it were not for Martini's name it is very 

 likely that the name Bulimvs, Seopoli, would have to be adopted 

 for this genus." This appears to me an entirely wrong conclusion, 

 for Seopoli at tlie reference cited (Introd. Hist. Xat. p. ?>^'2) 

 neither described nor referred to any species of the genus in ques- 

 tion, and the figure in Swammerdam's work (Bib. Xat. tab. ix. 

 fig. 4) does not represent Vivijjara fasciata as stated by Dall (he 

 cannot have seen the work), but is a fairly characteristic represen- 

 tation of a Lviiriwa, apparently L. stai/nalis. 



I do not for a moment believe that Seopoli intended that 

 Bulimvs was to be regarded either as distinct from or an emen- 

 dation of Adanson's Bulinus. I regard it as merely an oversight in 

 the spelling, or a printer's error. If he considered it distinct, surely 

 he would not have put Adanson's name after it; moreover he 

 clearly tells us (Delic. Flor. et Faun. Insub. 1786, p. 67) that, 

 following Adanson, he calls certain shells " Bidimos." I think the 

 preceding remarks fairly answer Mr. Call's question as to " how 

 we can avoid retaining Scopoli's name Bulinvis for the species Helix 

 tentaculata, Linne,"' now classified under Gray's genus Bytldaia, 

 for, if we take the figure of Swammerdam as his type, Baliinvs 

 would then replace Limncpa, and if we select the first species he 

 quotes (Helix j^mtris) it would take the place of Succinea. 



The objection raised by Mr. Dall against using Vivipaim.s on 

 the grounds that there is an impropriety in making the " bearer of 

 living young " a male, is of little importance. Perhaps it would 

 have been fortunate had Montfort used the feminine termination ; 

 but as he did not, I, for one, prefer to let the genus remain 

 Vivipaims as originally published.

This is one of the most interesting shells in the collection, and 

 belongs to that group of the genus Viviparus which I at one time 

 considered distinct, and described under the name Xeotltanma.
