Fischer's diagnosis of the typical asper. A specimen before me 

 marked E. proximo, A. Ad. is evidently synonymous. 



E. CIRCULATUS Anton. PL 37, fig. 16. 



Shell ovate-conoidal, umbilicate, reddish, granulate-cingulate, 

 sculptured with 4 large elevated distant cinguli on the penultimate, 

 9 on the last whorl ; aperture semi-orbicular, silvery ; throat with 

 elevated lines not attaining the edge of lip ; columella denticulate 

 at base. Separated from T. atratus by the color and number of 

 cinguli ; from pullalus by the same characters and the elevated lines 

 in the throat. Each whorl is very convex, cylindrical ; the upper- 

 most spiral is distant from the simple suture ; all of them are strongly 

 elevated, beautifully grained by elevated, oblique, fold-like in- 

 cremental striae. In most of the interstices there are one or rarely 

 two elevated, grained, lines. The color is pale reddish-brown, the 

 lirse articulated whitish and red-brown. The outer lip has fur- 

 ruws inside, corresponding to the external lirse, and numerous ele- 

 vated riblets. Perhaps these riblets are the concomitant of old 

 age, and all specimens lacking them are still immature. My material 

 does not permit me to decide this question.

E. INCISUS (Mke.) Philippi. PL 37, fig. 6. 



Shell globose-conoidal, narrowly umbilicate, rosy-whitish, sub- 

 tessellately painted with purplish-brown spots ; whorls cylindrical, 

 separated by canaliculate sutures, sculptured with strongly ele- 

 vated, profoundly crenated cinguli, 4 larger ones on penult., 9 on 

 last whorl ; aperture semiovate, columella straight, with a denticle; 

 lip crenate by the terminations of lirse, smooth inside. 



On the penultimate whorl I count 4 strongly elevated very prettily 

 grained lirse of equal size. The first stands far from the suture, 

 which is broadly channelled ; the two following inter-liral spaces are 

 narrower than the lirse, the two next following are wider and have 

 a little grained riblet. The last whorl has 9 large and 5-6 smaller 

 lirse. The throat is scarcely sulcate inside, the outer lip thick, not 

 denticulate, only furrowed to correspond with the external lirse ; 

 otherwise the mouth is just as in T. atratus. The coloration is
