three turns, somewhat turbinate, with deeply canaliculate sutures. 

 The protoconch is oblique with reference to the axis of the shell. 

 The spire of the shell pi'oper is not much elevated, its whorls are 

 narrow, separated by a linear suture, ornamented with a few 

 spiral threads and closely-set sinuous lines of growth. Body- 

 whorl sharply keeled at the periphery, and covered with fiat spiral 

 threads which become obsolete with age, except anteriorly. 



The figure accompanying Mr. Tenison-Wood's memoir above 

 cited refers to a young shell, and is practically unrecognizable. 

 The interpretation placed upon it by Professor Tate is here adopted.

This species does not appear to be described, except in the 

 explanation of the plate above cited, where the following words 

 occur: " Conus dennanti, sp. nov. {C. piillulescens, var., Tate)." 



The protoconch (Plate II. Figs. 8«-5) differs from that of 

 C. piillulescens in not being angulate, or turbinate ; it is com- 

 posed of three smooth, convex turns, imbedded in the crown of 

 the shell, being in fact the only part whicli stands above the flat 

 surface produced by the convolution of the shell-whorls proper. 

 This upper surface is much depressed, has linear sutures, and is 

 boldly, spirally striated. The periphery of the body-whorl is more 

 sharply keeled than any other Australian Tertiary Conus; the 

 surface of the whorl is covered by rather closely-set spiral linea- 

 tions and sinuous growth-lines. Aperture very narrow, outer
