 occasionally to be seen in caper ata also. Barlara is distinguished from

 other members of this group. 



The accompanying figures (pp. 384-7) are all drawn to the same 

 scale; the scale will be found next to the figure of gramdaia. It has 

 been thought desirable to add figures of the larger Helicids also, and all 

 of these have been redrawn under the same conditions and to the same 

 scale. The magnification of the original drawings is 1,200 diameters.
