PUPOIDES. 261 



moreover, a careful scrutiny of large series of specimens has con- 

 vinced me that P. fallax and P. coenopictus, at least, may readily 

 be separated by the characters of the peristome, which in fallaoc is 

 much more strongly developed, thickened, and expanded, and has 

 the upper margin more deflexed towards the body-whorl, forming 

 an obtuse angle \vith the outer margin which is but slightly 

 curved, whereas in ccenopicta the upper and outer margins together 

 form a regular curve.

The Cumiiig collection in the British Museum contains five 

 specimens of Pupoides lardeus. This form, which is perhaps only 

 a variety of P. ccenopictus, is larger, possessing one more whorl, 

 and is more conoid in the spire.
