138 M1TRELLA. 



C. PELLUCIDA, Reeve. PI. 51, fig. 52. 



Shell ovate, obliquely expanded towards the base, transparent, 

 smooth, spotted and flamed with orange-chestnut ; spire rather 

 short, acuminated ; aperture ovate, columella excavated, lip vari- 

 cose, purple-stained within, crenated, one-toothed at the upper 



part. Length, 8*5 mill. 



Habitat unknown. 



Has somewhat the form of a Nassa, and is so transparent as 

 to show the columella through the shell. 



C. LINEOLATA (Pease), Brazier. PL 51, fig. 53. 



Shell elongately ovate, smooth, shining ; w r hoiis six, the last 

 grooved at the base ; columella tridentate, outer lip very slightly 

 thickened, smooth or barely dentate within ; openly reticulated 

 with fine chestnut lines, with an irregular band of the same color 

 encircling the last whorl, and maculated with white ; this band 

 appears above the sutur.e on the whorls of the spire ; there is 

 also a chestnut band towards the base of the body-whorl. 



Length, 7-9 mill. 



New South Wales, Australia. 



This species was first described by Mr. W. H. Pease as C. macu- 

 /osa,a name preoccupied by Sowerby, having been previously con- 

 fused by Mr.Angas with C. dermestoides, Kiener,andb}^ Mr. Brazier 

 with G. lineata, Pease which, apparently by a slip of the pen, 

 he writes lineolata. Pease's description of lineata (I have no 

 specimen, and it has not been figured) scarcely covers this form, 

 and I therefore give the species the name under which it is so 

 well known to Australian collectors. 



C. LTNEATA, PeaSC. 



Shell small, solid, fusiform, turreted, whitish or variously 

 marked with reddish brown; spire acute; whorls plano-convex, 

 smooth, the last somewhat ventricose, and spirally striated at 

 the base ; canal produced ; sutures faintly impressed ; outer lip 

 thickened by a stout outer varixand dentated within ; columella 

 smooth, strongly arched ; aperture small, tortuous. 



Sandwich Islands. 



Unfigured, and unknown to me. See remarks under pre- 

 ceding species.
