1 HE rare little shells composing the group I have now formed 

 into the genus Conalix, seem to have escaped the observation of 

 modern systematic writers. They form a beautifully defined 

 link connecting the Cones with the Volutes, strictly so termed, 

 and their generic characters seem to be very constant and clear. 

 The present species varies more or less in the regularity of its 

 tessellated markings. The inside of the mouth is brown, and the 

 pillar has five plaits. Several specimens are in the Banksian Ca- 

 binet, from the Pelew Islands. The figures are enlarged to one 

 half more than the natural size.
