548 BULLIDiE. 



rather densely disposed spiral series of impressed dots, 

 which seem like the depressions which proceed from a de- 

 cussation of raised striae. The apertm-e is not quite so 

 capacious as in catena^ since the body occupies a rather 

 larger portion of the ventral area ; it is not either so con- 

 tracted above, where the outer lip, which advances very 

 decidedly posteriorly, and is much arcuated below, juts 

 out and curves up a little, thus forming a slightly an- 

 gular lobe. The course of the inner lip is not so 

 sinuous as in the preceding shell, the incurvation of the 

 pillar lip, which exhibits a slight disposition to reflection 

 above, being less pronounced. In the majority of speci- 

 mens the length is only a single line, but it attains some- 

 times to a tenth of an inch in length, and a third less in 

 breadth. 



The animal of Bulltea punctata has been observed by 

 Mr. Alder, from whose beautiful drawings our figure is 

 taken. It is of a darker colour than its congeners, being- 

 tinged and speckled with reddish brown on a yellowish 

 ground. Its capital disk seems different in shape, and 

 much shorter and broader than that of catena^ and the 

 margin of the mantle is not laciniated.
