490 BULLA. 



Shell usually about two inches long, and half an inch broad, 

 and shaped like a Cone ; the colour is white, and Born has 

 enumerated the following Varieties in the markings : 1st, with 

 scattered minute dots ; 2d, clouded with spots and dots ; 3d, 

 with dotted lines ; and 4th, with angular oblique lines : these 

 markings are generally of a reddish colour, and the shell is 

 sometimes wholly white.

Shell about an inch long, and half as broad, and agrees so well with 

 the Linnaean description of B. Cyprcea, that I have no hesi- 

 tation in considering it to be the same. The figures referred 

 to for this species by Born, Schroeter, Gmelin, and Schrei- 

 bers, are young Cypraeae. The spire is short, and the whirls 

 indistinct, and the pillar at its base has a thick, somewhat 

 striated oblique enlargement. 



ventricosa. 43. Shell ovate, ventricose, and of a 

 yellowish orange colour ; aperture effuse, 

 with a white smooth oblique enlargement on 

 the pillar.

Lamarck describes this species to be nearly an inch long, but 

 Lister's figure, which he says it in other respects resembles, 

 is half as large again, and it is much more ventricose than the 

 preceding species ; the spire is small, and the sutures indis- 

 tinct. 



ampla. 44. Shell elongated, semicylindrical, white, 

 and the spire very small; aperture effuse, 

 with a striated oblique enlargement on the 

 pillar.
