PUPOIDES. 261 



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

 vinced me that P. fdllax and P. ccenopictus, at least, may readily 

 be separated by the characters of the peristome, which m fallax i's 

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

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

 an obtuse angle with the outer margin which is but slightly 

 curved, whereas in aenopicta the upper and outer margins together 

 form a regular curve.

The Cuming collection in the British Museum contains five 

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

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

 and is more conoid in the spire.
