122 STROMBUS. 



Reeve. Some authorities identify this species with S. dentatus, 

 Linn.; I have otherwise interpreted the latter. 



S. CAILLTAUDI, Jay. Manual, vi, PL 34, fig. 18. 



Shell spirally striatc, chocolate-brown, interior of aperture 

 Ringed with the same color. Length-, 40 mill. 



Hob. unknown. 



Probably a young Strombus, although described as a Conus. 

 I am not able to identity it. I have figured it in the sixth volume 

 of this work, as above. 



Section VI. CONOMUREX, Bayle, 1884. 

 S. MAURTTIANUS, Lam. PL 8, figs. 89, 90. 



White, with chestnut or chocolate longitudinal interrupted 

 zigzag lines and spots, arranged in revolving bands, aperture 

 ridged within, carnelian or rose-red. Length, 2-2-5 inches. 



Mauritius. 



S. cylindricus, Swainson, and S. coniformis, Sowb. (fig. 90), 

 are synonyms ; the latter retaining obtuse nodules which gener- 

 ally are only seen upon 3'oung specimens. 



S. LUHUANUS, Linn. PL 8, figs. 91, 92. 



Shell often covered with a dark epidermis, under which the 

 markings are the same as in the preceding species, the columella 

 very dark chocolate or nearly black. Length, 2-2-5 inches. 



Philippines, Australia, New Guinea, Viti Is., etc. 



No differences of form which have been pointed out as distin- 

 guishing this and the preceding species, hold good when an 

 extensive suite is examined ; the only real distinction is the 

 narrow black deposit overlaying the columella in S. LuhuaniL*, 

 of which S. Mauritianus never appears to show even a trace. I 

 figure a very curious anomalous growth of this shell (tig. 92), 

 preserved in the Museum of the University of Ghent. 



S. labrosus and S. Isevilabris of Menke, are synonyms.
