 Nearly resembling the last in shape and in its dull surface, but 

 differs in having no umbilicus, and in its peritreme not being nearly 

 so continuous. The last volution has its suture brown, a brown 

 band in the middle and another round the columella. A single spe- 

 cimen only was found.

A species which in general appearance bears some resemblance to 

 Bulinus ovoideus of Brug. and De F., tab. 112. f. 5, 6. (the same as 

 B. Luzonicus, ' Conch. Illustr.' Bulinus, f. 53.) ; this species, however, 

 increases more rapidly toward the anterior part ; it has, moreover, 

 one more volution. The aperture is placed very obliquely, so that 

 the shell stands firmly when placed upon it. The dark burnt colour 

 of the anterior part of this shell is seen in every volution in the 

 form of a spiral postsutural band. It has a thick light-coloured epi- 

 dermis, of which some traces have not been entirely effaced. — G.B.S. 



A curious variety of the Dog, from Malta, presented by Her Royal 

 Highness the Duchess of Kent, was exhibited.
