PLAIflSPIKA. 161 



transverse ovalis : perist. tenue, marginibus convergentibus, 

 supero recto, basali breviter reflexo. 



"Diaiu. maj. 10, miii. 8, alt. 4 mill." (Pfeiffer.) 



Hah. India : JVagpore {Jerdon). 



This species appears to have escaped all the recorders as, with 

 the exception of Pfeift'er's aud Clessin's ' Nomenclator," the name 

 does not figure ia any text-book or fannal list. It is allied to 

 P. nilagerica, and may indeed be only a variety of that species. 

 The last whorl, however, is not contracted below behind the 

 peristome, the umbilicus is narrower and does not show as many 

 whorls, while the aperture is nearly horizontal and the margins 

 are not coutiiuioas. In colour it is corneous white, A specimen 

 in the Cuming collection measures 13'5 : 11 : 4 mm. 



The species — hitherto unfigured — is now illustrated from the 

 type in the British Museum.
