M1TRELLA. 141 



flexuous and white, columella with some slight granulations,

 A larger shell than C. Tayloriana , Reeve. 



C. ISABELLINA, CrOSSC. PI. 51, fig. 59. 



Shell elongated fusiform, smooth, yellowish brown, under a 

 thin epidermis of the same color; aperture pale violet, the outer 

 lip with obtuse interior denticulations. L. 8, diam. 3 mill.

 C. TAYLORIANA, Reeve. PL 51, figs. 60-62. 



Shell solid, ovate, smooth, shining; epidermis smooth, thin, 

 greenish yellow ; color of shell white, finely reticulated with 

 chestnut and flamed or spotted with chestnut on the spire and 

 upper portion of the body-whorl, suture with opaque white and 

 chestnut spots ; lip moderately thick, denticulated within.

Southern Australia. 



A somewhat variable shell both in form and coloring, as shown 

 by numerous specimens before me. I agree with the Australian 

 conchologists that C. albomaculata, Angas (fig. 62) is a synonym. 



C. ALBUGINOSA, Reeve. PL 51, fig. 63. 



Shell ovate, smooth, shining, transparent white, reticulated 

 with orange-brown, with a central light band ; whorls flatly 

 convex, the last somewhat twisted and grooved ; aperture small, 

 lip simple, slightly notched at the upper part. Length, 10 mill. 



Habitat unknown. 



The type of this species formed part of the Taylor collection. 



C. INTERRUPTA, Gaskoin. PL 51, fig. 64. 



Shell ovate, attenuated at both ends, rather solid, white, 

 encircled above and below by bands of crescent-shaped chestnut 

 spots ; spire somewhat turreted, whorls encircled by a groove 

 round the upper part, the body-whorl deeply grooved towards 

 the base ; aperture rather narrow, lip slightly notched at the upper 

 part, denticulated within. Length, 10 mill. 



Habitat unknown (Taylor collection).
