 lated with the same. Length, 1'4 inches. 



China, Philippines, Australia, Tahiti? 



C. praecellens, A. Ad. (fig. 88), is a not fully mature specimen, 

 and C. turriculatus, Sowb. (fig. 89), is still younger. 



C. ACULEJFORMIS, Reeve. PI. 23, figs. 90-94. 



Narrow, with elevated spire ; encircled with equidistant punc- 

 tate grooves, and flat interspaces ; white, with light chestnut spots 

 and two interrupted broad bands of chestnut cloudings. 



Length, 1-1*5 inches. 



Australia, Philippines, China. 



C. vimineus, Reeve (fig. 91), C. insculptus, Kiener (fig. 93), 

 C. longurionis, Kiener (fig. 94), and C. gracilis, Sowb. (fig. 92), 

 appear to be very nearly identical ; they can scarcely be classed 

 as varieties. 



C. D'OBBIGNYI, Audouin. PI. 23, figs. 95, 96.

Spire elevated, with compressed tubercles at the sutures ; body- 

 whorl encircled by tuberculated striae ; yellowish white. 



Length, 1*25 inches. 



Habitat unknown. 



Has much the appearance of the foregoing species. It is sup- 

 posed to be a fossil. First described by Kiener as C. crenulatus, 

 a name preoccupied by Deshayes, and therefore altered as above 

 by Mr. H. Crosse. 



C. ARCUATUS, Brod. and Sowb. PI. 24, fig. 98. 



Shell broadly and angularly shouldered, spire concavely ele- 

 vated, apex acute, body-whorl somewhat contracted below, with
