174 PAGODULINA. 



sharp, not expanded, not continuous. In pagodula as a rule 

 it runs up to the suture or beyond it, but in tschapecki it runs 

 straight forward; the impression in the middle is weaker. 

 Yet these last peculiarities of the peristome may be conse- 

 quent upon immaturity. 



"4. Finally, our Pupa lacks a punctiform lamella (which 

 authors have ignored), and which in pagodula is behind the 

 columellar margin, between the lamella traversing the last 

 whorl in the middle and the umbilical crevice" {Gredler). 



Obersteiermark : near the railroad station Peggau, at the 

 foot of steep limestone cliffs under stones and leaves, together 

 with hundreds of P. pagodula, truncatella, doliolum, etc. (H. 

 Tschapeck) .

While seemingly immature, the characters other than aper- 

 tural assigned may give this form standing when mature topo- 

 types can be examined. Probably, however, it is a case of 

 gigantism, a theory suggested by the length, the incomplete 

 peristome, and the fact that the specimens were picked out of 

 hundreds of " P. pagodula" (apparently = subdola). 



Gredler was in error in supposing that typical P. pagodula 

 has a punctiform palatal fold below the long median one, 

 that lower fold being characteristic of subdola and its vari- 

 eties, and wanting in P. pagodula. 



2b. Pagodulina subdola sanremoensis n. subsp. PI. 21, figs. 8, 9. 

 On a hill above San Remo on the Italian Riviera, Charles 

 Hedley collected specimens of Pagodulina which agree with 

 P. subdola by the cylindric shape, but differ by the much 

 thickened peristome. They are like P. subdola and P. s. 

 adamvi in the presence of a short lower-palatal fold, but differ 

 from the latter in the shape of mouth and umbilicus, as well 

 as of the whole shell, in having no suprapalatal fold, and in 

 the peristome, which is flesh-tinted and very much thickened 

 icithin. This thickening extends rather far inward on the 

 columella. The riblets are a trifle closer; on the last half- 

 whorl they are fine and close, as usual. Length 3.5, diam. 

 above aperture 1.85 mm. ; 8V2 whorls ; about 12 riblets in one 

 millimeter on the face of the penult whorl.
