CANTHARIDUS. 131 



brown. A very variable shell, smaller than C. tenebrosus. (Hut- 

 ton.) 



Bank^s Peninsula to Dunedin, N^. Zealand. 



Cantharidus pupillus Hutton, Proc. Linn. Soc, N. S. Wales, ix, 

 p. 562, 1884, etc, (not Trochus pupillus Gould, U. S. Expl. Exped. 

 xii, p. 186, atlas, fig. 208). 



My knowledge of this shell is derived wholly from Professor 

 Hutton's description and remarks. It is not the T. pupillus of 

 Gould, which is undoubtedly a species from the West coast of North 

 America. 



C. SANGUINEUS Gray. PI. 47, figs. 92, 93. 



Shell top-shaped, white, with rows of numerous blood-red spots ; 

 whorls flattened, the last obscurely keeled ; the front ratlier convex, 

 with sharp-edged, low spiral ridges. ( Gray.)

 Cantharidus sanguineus Hutton, Proc. Linn. Soc. N. S. Wales, ix, 

 p. 362 (1884) ; and var. ccelatus Hutton, I. c, p. 363. 



Hutton says of this species, which I have not seen. Shell im- 

 perforate, spirally grooved. Pinkish white, with red spots on the 

 ribs, or with red flexuous longitudinal markings ; interior and mouth 

 white. 



Var. c.ELATus Hutton. 



Smaller but more deeply ribbed and the grooves wider. (Hutton.)

 shining ; color brown, fawn-color or rosy, with widely-spaced light 

 or dark narrow spiral lines, usually four in number on the penulti-
