48 CHONDRINA OF THE PYRENEAN CENTER. 



Probably a large form of farinesii. 



30. CHONDRINA TARRACONENSIS (Fagot). Shell rather openly 

 perforate, regularly conic from the base, corneous-buff, irreg- 

 ularly striatulate ; whorls 8, somewhat convex, slowly increas- 

 ing, the last larger, ascending, rounded at the base. Aperture 

 vertical, ovate-lunate, with 1 to 3 teeth: angular smaller, 

 parietal more or less lengthened, or punctiform or wanting; 

 columella thick, toothed; peristome unexpanded, margins 

 nearly parallel. Length 6, diam. 2 mm. Spain. (Pupa tarra- 

 conensis Fagot, Catal. Moll. Essera (not seen) ; Westerlund, 

 Synopsis, 1897, p. 100.) Cfr. M. jumttl. v. ascendens W. 

 ( Westerlund) . 



31. CHONDRINA LONGINI (Fagot). Shell rimate-perf orate, 

 the perforation nearly covered by the columellar margin, 

 cylindric-conic, opaque, glossy, corneous-violaceous, at the 

 summit yellowish; irregularly and obliquely undulately stri- 

 atulate; spire tapering from base to summit, especially so in 

 the upper part, the apex corneous, smooth, mamillate, not 

 prominent, as though truncate; whorls 7%, a little convex, 

 separated by a well-impressed suture, regularly increasing, 

 the last larger, not compressed below but rounded, ascending 

 a little to the aperture. Aperture slightly oblique, ovate- 

 rounded, 3-plicate as follows: 1 tooth-like, porcellanous an- 

 gular ; 1 immersed, lamellif orm, compressed, tapering parietal, 

 also porcellanous ; 1 straight columellar, more or less incurved 

 at the summit ; peristome thickened at the aperture, the mar- 

 gins little approaching, the columellar margin lightly in- 

 curved, reflected at the umbilicus, outer margin simple, regu- 

 larly curved. Alt. 6, diam. 2 mm. ; alt. aperture l 1 ^, width 1 

 mm. (Pupa longini FAGOT, in Navas, Boletin Soc. Aragonesa 

 de Cienc. Nat., v, 1906, p. 201). 



Spain : pena Foradata above the Salient, Aragon, at an ele- 

 vation of over 2000 meters (R. P. Longin Navas). 



It is perhaps approached only by our Pupa saltus of the 

 Essera valley, and ignota of the valley of Panticosa ; but it is 

 distinguished from the first by the less numerous whorls (8 

 instead of 10), the last whorl rounded at the base and not 

 compressed, the aperture more oval-rounded, by its columellar 

 fold more immersed and curved at the top, etc.; from the 

 second it differs by the greater size, more swollen whorls, the 

 feebler teeth, etc. (Fagot). 



This is apparently the Pupa navasi Fagot, ined., mentioned 

 by Caziot, Ann. Soc. Linn, de Lyon, liii, for 1906 (1907), p. 

 197, from the same place.
