CONUS. 



Tar. BANDANUS, Hwass. PI. 1, fig. 2. 



The triangular white markings are more crowded than in the 

 typical form ; the colored markings form two irregular bands. 



Philippines, New Caledonia, Banda, etc. 



Var. CROSSEANUS, Bernardi. PI. 1, fig. 3. 



The chocolate reticulations heavier and closer. 



New Caledonia. 

 Tar. NIGRESCENS, Sowb. PI. 1 , fig. 4. 



Surface nearly entirely covered by the chocolate markings. 

 Intermediate states of coloring are quite common, so that the 

 division into varieties is arbitrar} 7 . 



Tar. PS KUDOM, \RMOREUS, Desh. PL 1, fig. 5. 



Shell regularly grooved throughout, spire rather more elevated, 

 not tuberculated, last whorl somewhat convex on the sides. 



Length, 2 inches. 



Habitat unknown. 



Described from a single specimen, and at most only a variety 

 of C. marmoreus. 



C. NOCTURNUS, Hwass. PI. 1, figs. 6, 7. 



Pattern of markings essentially the same as in C. marmoreus, 

 but the chocolate-color coalesces into two broad irregular bands 

 within which the triangular w r hite spots appear only occasionally. 



Length, 2-3 inches. 



Ceylon, Java, Mauritius, Moluccas, Viti Isles, etc. 



In C. Deburghise, Sowb. (fig. 7), the surface is sometimes 

 granular in revolving lines, and the nodules are compressed. 



C. ARANEOSUS, Hwass. PI. 1, figs. 8-10. 



Shell very closely reticulated with white and light chestnut, 

 the white spots crowded and irregular in size, the chestnut lines 

 forming two interrupted, irregular bands. 



Length, 2 5-4 inches. Ceylon, Philippines, Moluccas. 



Dr. Weinkauff has adopted the name C. peplum, Chemnitz, for 

 this species, but that author only happened to be binomial in 

 this instance, many of his other Cones being designated by a 

 descriptive phrase ; I therefore prefer to retain the better known, 

 if later name given by Hwass. This species is in part the (7. 

 arachnoideus of Gmelin.
