PUPA. 



165 



Animal grey-black. 



Shell the tenth of an inch long, brown or yellowish 

 horn-colour ; spire composed of six or seven rounded 

 and slightly striate volutions ; aperture semi- Fig. 44. 

 circular, with generally a small tubercular 

 tooth placed in the middle and deep within 

 the mouth, but which is sometimes very ob- 

 scure and often totally wanting ; peristome 

 thin, not margined, but slightly reflected 

 and forming an umbilicus ; and behind the outer 

 lip is a thick white rounded rib. 



This species varies very much in size, and in the 

 compactness of the spire, (fig. 44.) 



Captain Brown has added to the list Pupa uniden- 

 tata Pfeiffer (Brown, B. S. t. 41. f. 4.) and P. Uden- 

 tata Pfeiffer (Brown, B. S. t. 41. f. 6.). According 

 to Rossmasler (i. 83.), these species of Pfeiffer are 

 only varieties of P. marginata. Brown's figures are 

 so bad that it is not possible to determine what 

 species they are intended to represent. 



c. Peristome slightly reflexed; throat many-plaited; 

 cavity of the young shell simple. (Abida Leach.) 



73. 4. PUPA secale. Juniper Chrysalis Shell.

 striated ; aperture with seven or eight laminar 

 teeth ; the peristome acute and slightly reflected.
