CONUS.— Plate II. 



the rest that it almost requires the representation of a 

 dozen intermediate varieties to show the connection. The 

 abundant means of comparison which a tolerable number 

 of these shells, collected together in the same group of 

 islands, the Philippines, have afforded, leave no doubt of 

 their complete specific relation. They were found by 

 Mr. Cuming upon mud-banks at low water, and, there 

 is every reason to suppose, are confined to that locality. 

 This beautiful series of the Conus thalassiarchus forms 

 a most interesting addition to the genus, the species 

 having been only known hitherto by a few miserable spe- 

 cimens, such as were figured by Sowerby, for want of 

 better, in his 'Conchological Illustrations,' fig. 80 and 85. 



Species 9. (Mus. Stainforth.) 



Conus miles. Con. testa solida, pallide flavescente, fas- 

 cia fusco-ferrugined transversim, f Usque ftexuosis 

 palUdioribus longitudinaliter pictd ; fascia interdum 

 at rarb obsoletd; spird plano-obtusd, ftavidd ; basi 

 n igerrim o -fused . 



The soLniER Cone. Shell solid, pale yellowish colour, 

 painted transversely with a single dark ferruginous 

 band, longitudinally with undulated thread-like 

 lines of a paler colour ; band sometimes but rarely 

 obsolete ; spire flatly obtuse, yellowish ; base black- 

 ish brown.

No one can fail to distinguish this species, which, being 

 widely distributed over the globe, is brought in great 

 abundance. The shell here represented is of large 

 dimensions, and the markings are unusually clear and 

 well-defined. 



Species 10. (Mus. Stainforth.) 



Conus glaucus. Testa obeso-conicd, quasi turgidd, 

 (jlaueu-eieruleseente, lineis fuscis numerosis, inter- 

 ruptis, confertis, cinctd ; spird obtitso-convexd, mu- 

 cronatd, nigerriino-fusco maculatd ; basi striatd. 

 The grey Cone. Shell stoutly conical, as though 

 swollen, greyish blue, surrounded with numerous, 

 close-set, interrupted lines ; spire obtusely convex, 

 pointed, spotted with dark black-brown triangular 

 patches ; base striated.

The grey colour of this shell is perhaps its most 

 striking characteristic, for there are many dwarf vari- 

 eties of the Coni betulinus and Swalensis which approach 

 very near to it in other respects.
