BUCCINUM Tranquebaricum, and has called the second, PUR- 

 PURA mdanostoma ; he has given a figure of these two species in 

 his Genera, No. 25, pi. 5, fig. 5 et 6. 



The difference between young specimens and adults, has led 

 into this error : the latter, much larger, have their transverse 

 striae more prominent ; and the longitudinal folds of the lowest 

 whirl, which are distinguished in a very striking manner upon 

 the young specimens, disappear insensibly with age.

B. testa ovata, longitudinaliter plicata, 'tran verse sulcata et striata,rufes- 

 cente ; plicis nodiferis ; ultimo anfractu superne angulato ; spira exsertius- 

 cula ; apertura alba ; labro crassiusculo, inttis striato. 



Shell ovate, thick, solid, bi-conical, whitish, covered with a 

 reddish epidermis, having nine or ten longitudinal folds, more 

 strongly marked upon the last whirl, rarely prolonged as far as 

 the base, and regularly divided into tubercles by more promi- 

 nent transverse striae, the interstices of which are furnished 

 with other much finer and very approximate striae ; spire ob- 

 tuse at its summit, composed of five or six slightly distinct 

 whirls ; the lowest very broad, flattened at its upper part, and 

 sub-angular ; aperture white, ovate, narrowed at its base, 

 canaliculated at its upper part, at its union with the lip which 

 is thin and denticulated at the edge, striated within. Exter- 

 nally, in adult shells, a pretty prominent varix is observed. 

 Columella slightly bent, furnished throughout its whole length 

 with small nodules.
