Tamaulipas: Canon 4 miles west of Victoria. Types No. 85,917, 

 A. N. S. P., collected by S. N. Rhoads, January 21, 1903. 



A small, sharply striate species. The aperture is larger than in 

 G. delicatula. Another specimen of the type lot has a somewhat 

 shorter spire, measuring: length 22.5, diam. 9, length of aperture 

 13.3 mm. 

 Glandina delicata alticola n. subsp. PI. XLVIII, fig. 2. 



Shell smaller and more cylindric than G. delicata, with compara- 

 tively stronger sculpture, 6 whorls and decidedly curved columella. 

 Length 17, diam. 6.5, length of aperture 10 mm. 



Diente, near Monterey, State of Nuevo Leon. Types No. 77,174, 

 A. N. S. P., collected by S. N. Rhoads. 

 Glandina oblonga tamaulipensis n. subsp. PI. XLVII, figs. 6, 6a, 66. 



Shell narrowly oblong, the last whorl somewhat cylindric, spire 

 slowly tapering to a rather large, obtuse apex. Surface very glossy, 

 smooth except for irregularly spaced, rather distinct and unequal, 

 impressed lines in the direction of lines of growth; and the suture is 

 bordered with fine short and close folds. Whorls fully Ih, regularly 

 increasing, the last suture not more obliquely descending. Aperture 

 about half the length of the shell, the outer lip arched forward in the 

 middle, basal lip retracted; columella short, very concave above and 

 convex below. 



Length 15, diam. 5.7, length of aperture 7.5 mm. 



Length 15, diam. 5.3, length of aperture 7.3 mm. 



Tamaulipas, in a canon about 4 miles west of Victoria, elevation 

 about 3,000 feet. Types No. 85,910, A. N. S. P., collected by S. N. 

 Rhoads, January 21, 1903. A single specimen taken at Diente also 

 seems to belong here. 



This form, which was found in abundance, is evidently close to 

 G. ohlonga Pfr.,^ but it is less plicate below the suture and the columella 

 is more curved. Fig. 6 represents a young shell.

Glandina iheringi Pils., Nautilus, XIV, p. 4 (May, 1900), is a synonym of 

 this species.

Several specimens taken at Diente, near Monterey, N. L., seem refer- 

 able to this species, described from the Province of Vera Cruz.
