BOCOURTIA. 23 



3 convex, the rest rather flat, with a narrow white line bordering the 

 suture below; obliquely striate and sculptured with obsolete, spiral, 

 impressed lines ; the last whorl large, obtusely angular in the middle, 

 malleate or corrugated, and obliquely striate. Aperture inverted 

 ear-shaped, colored like the outside, and two-thirds the length of the 

 shell ; peristome white, hardly thickened, lightly expanded, the col- 

 umellar margin narrowly reflexed over the perforation. 



Length 26, diam. 20 mill.; aperture 16 mill, long, 11.5 wide.

4 ' This species is very peculiar, and does not suggest a comparison 

 with any other known form. It hardly agrees with the genus Calycia 

 in the expanded character of the peristome, but it appears to approach 

 that group more closely than any other." (Smith.) 



I have not seen this species, but from the form of the columella 

 and lip, convex early whorls, and greenish cuticle, it seems to belong 

 to the Beddomea or Pseudopartula stock, rather than to Calycia. I 

 do not feel justified, however, in changing the generic position as- 

 signed by the sagacious author of the species, without myself seeing 

 the shell ; especially as the specific name is pre-occupied in Amphi- 

 dromus (A. everetti Fult., Jan., 1896). 



Genus BOCOURTIA Rochebrune, 1882. 



Bocourtia ROCHKBR., Bulletin de la Societe Philomathique de 

 Paris (7), xvi, 1881-2, p. 117. 



Shell imperforate, ovate-oblong, sulcate ; whorls subventricose, 

 covered with a tawny epidermis ; columella subcallous, curved ; aper- 

 ture ovate elliptical, the lip unexpanded, simple. (Rochebr.} 



These shells are said by M. Rochebrune to be the exact but exag- 

 gerated counterpart of Limncea palustris, from which they differ 

 anatomically, though no details of this are given. The genus, if such 

 it be, is unknown to other authors ; and is inserted here merely to 

 complete the account of oriental Bulimi. Rochebrune does not state 

 whether the mollusk is aquatic or terrestrial, but the latter would be 

 implied.
