COLUMBELLA. 



C. VERSICOLOR, Sowerby. PL 45, figs. 84-96. 



Shell ovate, with moderate spire, the whorls swollen at the 

 shoulder, beneath which the boc]3-whorl is more or less con- 

 stricted, shoulder sometimes sparsel}', obsoletely tubercnlated ; 

 yellowish white, with zigzag chestnut or chocolate close longitu- 

 dinal markings, often shaded with white ; on the middle of the 

 body-whorl these markings are often broken up into numerous 

 small punctations ; aperture white within ; columella tuberculate, 

 witli two prominent teeth in the middle. Length, 'S-'^S inch. 

 Indian Ocean; Japan; Philippines; Australia; Polynesia. 



The oldest name for this species is C. scrijjta, Lam., but 

 Linnseus had preA'iously used this name for a well-recognized 

 Mediterranean species. G. bidentata, Menke (flg. 81), is also a 

 S3'nonym, and very probably C. variegata, Menke. The latter 

 name would have priority if it could be satisfjictorily identified. 

 The synonymy will include C araiieosa, Kiener (fig. 88), C. 

 coroncita, Duelos (fig. 89), C. athadona, Duclos (figs. 90, 91), C. 

 figrinn, Duclos (figs. 92, 93), C. aspersa^ Sowb. (fig. 94), C. nivo.sa 

 (fig. 9o) and G. perlusa (fig. 96), Reeve, the two last erroneously 

 ascribed to Guatemala in the original descriptions.

 prominent, sometimes extending the entire length of the shell, 

 usually becoming obsolete towards the middle, and occasionalh' 

 not developed at all. Color, white and chestnut or chocolate in 

 alternate revolving bands, the latter usually broken up into short 

 irregular longitudinal markings ; sometimes the bands are not

Viti, Oalapagofi and Sandioidt Islands. Acapulco? 



PhiUppines, New Guinea. 



This species is smaller, more tuberculate, and in the banded 

 specimens differently colored from the preceding one ; the colored 

 base of the columella is also a good distinguishing character 

 The figure from Reeve's Iconica (fig. 99), shows a ribbed state
