340 CALLIOSTOMA. 



C. SOWERS YI Pilsbry. PI. 18, fig. 17. 



Shell acutely sub-elevated conic, thin, brownish-flesh-color, spirally 

 encircled by minute, interrupted close brown lines, banded with 

 ashen toward the apex; whorls 10, scarcely convex, the earlier 

 granose-lirate, succeeding smooth, the last at the suture subcon- 

 spicuously granose-lirate, the lirse becoming then almost obsolete ; 

 suture impressed, margin obtusely carinated, ornamented with sub- 

 distant reddish spots ; base plano-convex ; aperture obliquely 

 quadrate, throat pearly ; columella callous, oblique, scarcely in- 

 curved. Alt. 30, diam. 33 mill. (Sowb.)

Z. jucundus SOWB., P. Z. S. 1878, p. 798, t. 48, f. 6 (not T. jucundus 

 Gould, also a Calliostoma). 



I can add no information to the above. 



C. ORNATUM Lamarck. PI. 16, fig. 3. 



Shell conical, imperforate, rather solid but not thick, pale yellowish, 

 with radiating brown flames above, the base dotted with brown and 

 whitish. Surface of whorls encircled by spiral lirse, uneven in size, 

 and cut into very close compressed granules ; there are about 10 such 

 lirse on the penultimate whorl, but the number is variable owing to 

 the greater or less development of interstitial riblets ; the base has 

 10-13 concentric riblets, which have a tendency to split or become 

 double ; they are wider than the interstitial furrows. The spire is 

 elevated, conical ; the apex acute ; sutures slightly impressed. Whorls 

 about 7, slightly convex. There are generally two or three stronger 

 lirse near the middle or periphery, and this gives at times a slightly 

 bicarinate outline to the body-whorl ; base flattened, a little convex ; 

 aperture subrhomboidal, smooth inside; columella arcuate, often 

 bounded by a purple streak. 



Alt. 20, diam. 22 mill. ; alt. 18, diam. 20 mill.

Resembles somewhat the subbiangulate, lirate Chinese species of 

 Calliostoma. The sculpture though variable is characteristic.
