body-whorl, and in the development of the nodulations on the 

 angulation of the whorls, in some forms being very faint or 

 almost entirely absent, while in others they are very strongly 

 marked. 



28. Voluta stPOphodon, var. stolida, Johnston. 



V. strophodon, McCoy, Prod. Pal. Vic. Dec. IV., pp. 25, 26, 

 pi. xxxvii., figs. 2-4^. 



V. stolida^ Johnston, P.R.S.Tas., 1880, p. 36, and Geo. Tas.,

V. strophodon, Tate, Gast. II., 1889, p. 134. 



Observations. — Mr. Johnston in the work quoted above figures 

 a shell (pi. XXX., tig. 7) as V. tveldii, T. Woods, which is clearly 

 not that species. Professor Tate apparently regards it as 

 V. strop/wdon, McCoy ; for my own part I regard it as the young 

 of Johnston's V. stolida, figured on the same plate. With regard 

 to V. stolida, Johnston, Professor Tate places it amongst the list 

 of unclassified species in his Gasti'opoda, Part II., p. 121, and 

 merely remarks that it is related to V. strophodon. With this I 

 agree, but as the shell shows distinct variation from the typical 

 form of V. strophodon, as figured by Sir F. McCoy, it seems to 

 me to be the most satisfactory course at present to retain a 

 varietal name for this form, and it is in this sense that I use Mr. 

 Johnston's name stolida. 



29. Voluta tateana, Johnston.

V. stephensi, Tate, Gast. II., 1889, p. 122. 



Observations. — Professor Tate regards this species as being 

 closely related to V. heptagonalis and V. alticostata, but, appa-
