Conus milesi. 



Testa anguste fustformis, alba, maciilis fitscis tj-regi/laribi/s longi- 

 iudinaUbus oniata, sulci's tmnsversis a/igusfis pitndatis 

 scidpta ; spira elongafa, concava, alba, fusco maculata ; 

 anfractus lo, supremi duo globosi, Icevigati, ca^teri superne 

 decUves, dein angiilati, ad angiiluin concinne coronati, supra 

 siilcis spiralibiis i — -2 a rati ; apertiira angustissima, longit. 

 tot ins ^ fere cequafis : lab rum arcuatum, superne subprofuude 

 sinuatum. 

 Longit. 21 mill., I at. i\ ; apertura 13 longa, \\ lata. 

 Hab. : Muscat, Arabia, 5 — 20 fathoms. 



This species is well distinguished by its fusiform shape, its 

 coronate spire, the style of coloration, and the spiral grooves, 

 which are about thirty in number on the body-whorl, and finely 

 punctured or pitted. 



The figure of C. scalaris, on plate 88, in Kiener's "Coquilles 

 Vivantes," gives a very fair idea of the form of the present species, 

 which is, however, a trifle narrower at the shoulder. The mark- 

 ings are disposed very much as in C. acutangulus, Kiener 

 (1. c. plate 72, fig. I, figure on right), but are in somewhat larger 

 patches. 



The single specimen was presented to the British Museum, 

 by Colonel J. B. Miles, with whose name I have associated the 

 species. 



Conus eburneus var. 



The British Museum has recently obtained from Mr. 

 Sowerby, a shell about an inch in length, which on exami- 

 nation, I believe to be a variety of this common species. It is 

 probably only about half-grown, and diifers from the normal
