154 AGARDHIA. 



ing nearer to excessiva; but it differs from both by the fine, 

 thread-like striae. These gradually disappear on the last 

 whorl, the last fourth being very glossy and nearly smooth. 

 The short basal fold is so far in that it is generally not visible 

 in a direct front view. The lower-palatal fold is moderately 

 long, running forward into the callus within the lip. The 

 upper-palatal is quite short. Typically there is but one 

 lamella on the parietal wall, but in the form euodon a small 

 tubercular angular lamella stands far within near the parietal 

 lamella. 



Kimakowicz notes that "the young stage of this species is 

 like that of Orcula doliolum except that it has no folds or 

 lamella?, these being only developed in the completed shell. 

 The gimlet-hole shaped umbilicus of the earlier whorls is 

 closed after the end of the sixth whorl. The smallest full- 

 grown example of my collection was collected by Dr. Jickeli 

 at Bad Borszek. It has the dimensions: height 4.5, diam. 

 1.7 mm., 8% whorls. The largest, taken by Dr. Petri from 

 Schassburg and Korongyis in the Rodna Mountains, height 

 6.7, diam. 1.7 mm., 11 whorls. The diameter has been given 

 by all authors too large. Of the many shells before me, none 

 reaches a diameter of 2 mm., but at most 1.8 mm." 



Kimakowicz further notes that the form euodon West, is 

 sometimes found in Transsylvania. The very small subcolu- 

 mellar tooth and the small denticle between parietal lamella 

 and suture are often present. But everywhere the characters 

 of the typical form predominate, so that he does not count 

 var. euodon of Upper Hungary and Galizia as a member of 

 the Transsylvanian fauna. 



A. oielzi euodon (Westerlund), pi. 16, figs. 15, 16, is de- 

 scribed as having two parietal teeth, the outer one small, thin, 

 deeply placed; two on the columella, the upper long, strong, 

 the lower tooth-shaped; three in the palate, the upper one 

 lengthened, the third wart-like. The palate often has a red- 

 dish-white or whitish callus. Length 5 to 7, diam. 2 mm.

This is a northern race of Galicia and the Tatra range, but 

 specimens with the same characters occur sporadically in
