Ilaf,. ? 



This species appears to be distinct in respect of fonn, 

 and may ])rove to be uniformly as colourless as the spe- 

 cimen here figured.

 Fig. b, Mus. Steere.)

 Varictates. 



Oliva nedulina and ozodona, Duclos. 



Hab. Bay of Panama (in sand and on nuid l.ianks at low 

 water) ; Cuming. 



It has been necessary to figure several examples of this 

 species to show its variety of colouring, the pattern of 

 which is sometimes disposed in promiscuous waves and 

 sometimes in broad triangular dashes.

The belted Olive. Shell acuminately oblong, rather 

 inflated, spire exserted, columella callous at the upper

 depth of ten fathoms) ; Cuming. 



This very pretty species is constantly distinguished by 

 its delicate wave-streaked painting and dark-lirown basal 

 zone. The plaiting of the columella, as above described, 

 is also pecidiar.
