CAUCASIAN LAURLE. <^> 



Pfeiffer's type has not been figured. The figures now given 

 are from a somewhat smaller Kobi specimen. The thin but 

 high angular lamella is connected by a callus with the lip- 

 insertion. It bears a tubercle on the right, opposite the labral 

 tubercle limiting the rounded sinulus. The parietal lamella 

 is stouter, lower and much deeper in. The columellar lamella 

 does not emerge, and forms a flat, steeply sloping plate deep 

 within. The lower-palatal fold is high within; above it, and 

 partially connected by an entering callus, there is a low en- 

 tering fold, arising from the lip-callus a short distance below 

 the sharp tubercle bounding the sinulus. The basal fold is 

 exactly median and short. Length 4.9, diam. 2.4 mm., I 1 /* 

 whorls. 



16. Lauria paulin^e Lindh. 



The dextral shell is small, rimate, ventricose-ovate, thin, 

 translucent, finely striate, hardly glossy, reddish-brown. The 

 spire is inflated-conic, with convex sides and rather pointed 

 apex. The 7 to iy 2 convex whorls increase regularly and 

 slowly, the last is about twice the height of the preceding, 

 ascending in front, and somewhat compressed at the base. 

 Suture impressed and nearly horizontal. The vertical aper- 

 ture is truncate-oval, with two bays and narrowed by various 

 teeth. The outer parietal [angular] fold is simple and high, 

 the inner far lower and emerges less than the outer. On the 

 outer margin there is a sort of tubercular denticle below the 

 sinulus, below it a rather long and high palatal fold and a 

 shorter basal fold. On the columella there are two short, 

 horizontally placed brown folds, and behind them, in the in- 

 terior, a nearly vertical, semicircular plate-like white lamella, 

 which is well seen in an oblique view in the aperture, and 

 shows through externally in the circum-umbilical region as a 

 lightly bowed streak. The lip-margins are not connected, 

 distinctly reflected, very thinly lipped; the outer margin is 

 strongly impressed below the sinulus, the columellar oblique. 

 Length 3.25-3.5, diam. 1.75-1.8 mm. (Lindholm). 



Transcaucasia: near the railroad station Notanebi (37 werst 

 northward of Batuni), in swampy, mixed deciduous forest 

 (Lindholm).
