22 CONUS. 



.A species of wide distribution, and apparently everywhere 

 common. There is considerable variation in the height and cor- 

 onation of the spire, as well as in the color and pattern of the 

 markings, and the consequence has been the description of 

 several species, which the large series of specimens before me 

 compels me to unite. C. minimus of Linnaeus has been identi- 

 fied with members of this group, but, as pointed out by Dr. 

 Weinkauff, erroneously. The latter author has made C. minimus 

 = C. achatinus. Hanley did not find any shell labeled minimus 

 in the Linuean collection. The synonyms include C. tiaratus, 

 Brod. (fig. 85), C. fulgetrum, Sowb. (fig. 86), C. scaber, Kiener 

 (fig. 87), and C. coronatus, Dillw. 



Yar. ABBREVIATUS, Nuttall. PI. 5, fig. 89. 



The spots are more distant and somewhat more regularly 

 disposed. 



Sandwich Island*. 



C. Barbadensis, Hwass (not Reeve), is probably identical, and 

 does not inhabit the West Indies. 



Yar. ARISTOPHANES, Duclos. PI. 5, fig. 90. 



Shell violaceous gray, somewhat clouded with pink-white, the 

 revolving lines milk-white, interrupted by chestnut short dashes 

 and spots. 



Eed Sea, Philippines, Polynesia. 

 C. BACCATUS, Sowb. PL 6, fig. 92. 



Shell minutely decussated, with regular rows of conspicuous 

 granules ; whitish, with large orange blotches arranged in three 

 bands ; spire-whorls concave, nearly smooth ; body-whorl with a 

 triangulate shoulder. Length, 23 mill. 



Habitat unknown. 



Described from a unique specimen in the collection of Dr. 

 Prevost, of Alenon. 



C. REFLECTUS, Sowb. PI. 6, fig. 91. 



Shell pear-shaped, anteriorly granulated, otherwise smooth, 

 \vry minutely coronated, spire closely grooved ; whitish, with 

 two l.nmd bands of rose-color clouded with brown. 



L< ngth, 25 mill.
