 columella in the throat. Length 3.5, diam. above aperture 

 1.6 mm. ; nearly 8 whorls.

Pupa (Pagodina) pagodula Desm. var. gracilis Boettger, 

 Nachrbl. D. M. Ges., xiv, 1882, p. 180 (no description). — Pupa 

 pagodula forma gracilis Bttg., Westerlund, Fauna, iii, 1887, 

 p. 91. 



The narrower shape, the less ascending last whorl, deviating 

 much less also in the umbilical region, and the widely-spaced 

 riblets of the last half-whorl, all separate P. s. gracilis from 

 P. pagodula and P. siibdola. It resembles the latter in pos- 

 sessing a well-developed lower-palatal fold. 



I have not found Dr. Boettger 's description of this form. 

 In the place cited above he mentions that "pagodula, typical, 

 transitions to var. gracilis and var. gracilis Bttg." were ob- 

 tained by sieving at Spizza-Sutomore in southern Dalmatia. 

 "Were it not for the transitions he alleges, I would think this 

 a distinct species. These transitions should be investigated 

 further.

Differs from typical pagodula by the more conic-ovate 

 spire, the less convex whorls, which are densely and acutely 

 rib-striate, the last one less distinctly impressed longitudinally, 

 ascending more. The aperture is less oblique, obliquely trun- 

 cate above ; [peristome] less impressed below the sinulus and 

 scarcely tuberculate there. Alt. 3.5, diam. 2 mm {Boettger) . 



Internally there is a well-developed columellar plate, a 

 moderately long palatal fold and a weak spiral lamella (on 

 the upper wall), in the same positions as in P. pagodula; 

 there is no lower palatal fold. Externally the last whorl is 

 not impressed though slightly flattened over the palatal fold. 

 On the face of the penult whorl there are about 15 strise in 1
