PAGODULINA. 179 



mm. Length 3.7, diam. above aperture 1.9 mm.; S 1 /^ whorls. 

 Caucasus region: woods near Lenkoran, abundant; a few 

 in the drift debris of the Lenkoranka (Leder). 



Pagodina pagodula (Desm.) var. lederi Boettger, in 

 Kadde's Die Fauna und Flora des siidwestlichen Caspi- 

 Gebietes, 1886, p. 305, pi. 3, f. Sa-d; also in Jahrb. D. M. Gtes., 

 xiii, 1886, p. 253, pi. 8, f. 8a-d. 



In the absence of evidence of intergradation with P. pago- 

 dida, this seems specifically distinct. Figured from a Len- 

 koran specimen from the Boettger collection. 



4. PAGODULINA (?) BOURGUIGNATI (Cout.). 



Shell minute, umbilicate, globose-cylindrie, very elegantly 

 obliquely lamellicostate. Spire very obtuse, the apex smooth. 

 Whorls 5, strongly convex, separated by a deep suture, the 

 earlier ones increasing rapidly, the last two nearly equal, but 

 the last a little smaller and ascending to the aperture. Aper- 

 ture subrotund, with sinuous outer margin and having folds 

 as follows: a very deeply remote palatal fold, not visible; a 

 strong translucent spiral-lamella, reaching nearly to the aper- 

 ture. Peristome a little expanded throughout, the margins 

 strongly converging. Height 1.4, diam. 0.95 mm. (Cout eigne).

 Malaeologique du Bassin du Rhone, in Ann. Soc. Linneenne 

 de Lyon, xxviii, 1882, pp. 22, 39. 



This form appears to be distinct by its few whorls, the very 

 small size and the long parietal lamella, reaching nearly to 

 the aperture. It seems strange that a form found in a De- 

 partement so well known has not occurred to other collectors. 

 The small number of whorls as well as the minute size sug- 

 gest that this may be a Vertigine snail. It cannot be a young 

 P. pagodula as Westerlund thought.
