392 CALLIOSTOMA. 



greenish, spirally sulcate, the 2d whorl somewhat granulate ; the 

 rest of the whorls smooth, flat, with a narrow supra-stitural fasciole, 

 which on the last whorl is not developed ; periphery rounded- 

 angular ; base smooth except for about 4 fine riblets around the axis ; 

 whorls about 9. Aperture smooth within, columella a trifle swollen 

 at base, nacreous, and either purple or whitish inside.

This form is separated from C. co-uulnin by absence or great 

 reduction of the granulation on the earlier whorls, the less distinct 

 supra-sutural fasciole, entirely effaced on the last whorl. It is 

 narrower than C. laugieri, and smoother ; but in my opinion will 

 prove to be connected by intermediate examples with that species. 

 A purple form of this species is among the color varieties before me.

Shell similar to T. dubius and T. conulus, but smaller, generally 

 darker in color, the apical whorls not (or but slightly) granulate. 



The form is straightly conical ; apical whorl minute, smooth ; 

 following whorls, to the number of three or less, granulate; then 

 there are several spirally grooved whorls, the lower ones either 

 smooth or grooved. The supra-sutural fasciole is distinct, articulated ; 

 base spirally grooved, sometimes smooth except around the axis. 

 Whorlsabout 8, color, (1) dark olive-green or olive-brown, unicolored 

 or longitudinally clouded with brown and lineolate with bluish, (2) 

 yellowish, clouded with brown or yellow, (3) uniform purple. 

 Aperture sulcate or smooth inside.
