beana, and exhibit the tendency of the parietal lamella (which 

 is very weak and deep in the throat, therefore readily over- 

 looked) to complete degeneration. The dimensions are be- 

 tween 6 to 7 mm. long, 2.5 to 3 wide; the number of whorls 

 from 6 to 7y 2 .

Manual XXV, p. 40, pi. 4, figs. 5, 6. 



Pupa obliterata Kstr. (Manual XXV, p. 52, pi. 5, figs. 9, 

 10), which Pilsbry thought resembled east Spanish forms, is 

 strongly and irregularly striate according to Krister's diag- 

 nosis. It may have been based upon a weakly ribbed and 

 weak-toothed specimen of C. lusitanica.

Kobelt 's otherwise expressive diagnosis, which Pilsbry (I.e.) 

 repeated, requires alteration as to the apertural dentition. I 

 looked through his entire original series, among them the type, 

 and found in this and all the other specimens the tooth formula 

 2-2-4, the suprapalatal fold always being weaker and never 

 reaching the peristome ; the basal-fold stands quite in the 

 lower angle of the aperture, and is as strong and long as the 

 two palatals. The cotype figured in pi. 26, figs. 13, 14, shows 

 these conditions. 



This form can stand as a dwarf form of the typical lusi- 

 tanica, with which it agrees in nearly all points. It differs 

 from that by the free, long, spiral lamella, which is not in the 

 line of projection of the angular lamella but standing a little 

 higher and beginning in advance of the end of the angular. 

 The teeth are just as strongly developed as in the typical lusi- 

 tanica, and thus the narrower mouth, consequent on the gen- 

 eral smallness of the shell in comparison with lusitanica, ap- 

 pears quite obstructed.
