8 _ CONUS. 
Var. 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. 
Var. 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 arbitrary. 
Var. PSEUDOMARMOREUS, Desh. PI. 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. nocrurNnus, 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 white spots appear only occasionally. 
Length, 2-3 inches. 
Ceylon, Java, Mauritius, Moluccas, Viti Isles, etc. 
In C. Deburghiz, 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 C. 
arachnoideus of Gmelin.
