divided by a white one ; I. Reddish brown, with a single 

 white band; K. Reddish brown, with a red and white band 

 united ; L. Blackish brown, with the band and base white ; 

 M. Pale purple, widi a sulphur-coloured band ; N. Pale 

 brown, with the band and base white ; O. White, with a 

 blackish red broad band ; P. White, with two narrow red 

 bands ; Q. Yellowish green, with scattered black dots and a

RAPA. 82. Shell sub-umbilicated, nearly globular, 

 with minute excavated dots, and the upper 

 part of the body-whirl deflected inwardly.

Inhabits 



Shell about an inch and a half in diameter, white, becoming 

 yellowish upwards, and marked transversely with a red band ; 

 it is punctured all over with excavated dots, which are so 

 minute, that the naked eye can hardly discover them. Mul- 

 ler suspects that young shells have an open umbilicus, and 

 that it becomes with age almost entirely closed over by the 

 reflected pillar-lip. 



CASTANEA. 83. Shell umbilicated, sub-giobular, 

 with seven striated whirls ; aperture without 

 any pillar-lip.

part 2. p. 135. t. 131. f. 1177 and 1178. Gmelin, 



p. 3629. 



Inhabits ■ 



Shell about an inch and a half in diameter, thick, of a dull 

 yellowish chestnut-colour, with a darker and white united 

 band round the middle of the body-whirl, which is conti- 

 nued along the sutures of the spire ; it is said to have seven 

 whirls, with crowded striae, and a moon-shaped aperture 

 without any pillar-lip. According to Muller, it is an inter* 

 mediate species between H. citrina and H. Algira. 



GLOBULUS. 84. Shell sub-umbilicated, thickish, 



somewhat globular, white, with five whirls, 



and the spire produced; outer lip margi- 



nated.
