196 EUGLANDINA. 



45. E. LAMYI (Fischer et Chatelet). PI. 23, fig. 28. 



Shell whitish, rather solid, with long, slightly convex, nearly 

 conic spire. Whorls 9 1 /, the first three smooth and glossy, 

 forming an obtuse apex; following whorls slightly convex, 

 parted by a deep suture, sculptured with irregular plicae of 

 growth, which are fewer and stronger near the suture. Last 

 whorl hardly descending, subcylindric. Aperture half the 

 total length, contracted above, rounded beneath, the margins 

 joined by a thin callus. Columella strongly intorted, deeply 

 emarginate at the base. Length 82, diam. 29, aperture 41 

 mm. (F. et C.). 



Mexico: near Cardenas, State of San Luis Potosi (Jan-

 321, pi. 13, f. 10; liv, 1907, p. 270. 



This species may be compared with E. liebmanni Pfr., but 

 that has a more obtuse apex, the plicee form veritable teeth 

 at the sutures, and the columella is decidedly less arcuate than 

 in E. lamyi.

49. E. MAZATLANICA Martens. PI. 23, figs. 39, 40. 



Shell subcylindric, rather solid, closely costulate-striate, 

 corneous-brown. Whorls 6 1 /o, a little convex, the apex ob- 

 tuse ; suture subangulate, lightly margined, scarcely crenulate. 

 Aperture nearly half the total length, lanceolate, the outer 

 margin arcuately produced; columella rather straight, ab- 

 ruptly truncate. Length 30 to 32, diam. 11.5 to 13, aperture 

 15 to 16 mm. long, 6 to 6.5 wide (Marts.) .

' ' This species is somewhat intermediate between G. pseudo- 

 turris and G. albersi, the color and suture is as in the former,
