85,910, A. N. S. P. (S. N. Rhoads). A single specimen taken~ 

 at Diente near Monterey, N. L. 



Glandina oblong a tamaulipensis PILS., Proc. A. N. S. Phila. 

 1903, p. 772, pi. 47, f. 6. 



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

 to G. oblonga Pfr., but it is less plicate below the suture, the 

 aperture is shorter and the columella is more curved. Fig. 

 17 represents a young shell.

Shell thin, slender, turreted and slowly tapering above, 

 broadest near the base, which is rather "saccate.' 7 Brown, 

 slightly translucent, smooth and glossy throughout, except for 

 rather separated, very short impressed grooves below the su- 

 tures forming a series of very short, low folds there ; and there 

 are a few impressed, sinuous, longitudinal grooves each ac- 

 companied by a whitish streak reminiscent of former peris- 

 tomes, on the last two whorls or more, two or three being on 

 the last whorl. Spire long, with very slightly convex lateral 

 outlines and quite obtuse apex. Whorls 8%, slightly convex, 

 the last one compressed laterally and decidedly full below. 

 Aperture small, very narrow above, broad below, the outer 

 lip pale-edged, thin, bent forward in the middle, strongly 

 retracted below, giving the basal lip an effuse aspect. Colu- 

 mella short, strongly concave and conspicuously truncated 

 below. 



Length 20, diam. 6.5, length of aperture 10 mm. 



Length 20.5, diam. 6.8, length of aperture 10 mm. 



Length 18.8, diam. 6.8, length of aperture 10 mm.

Glandina dalli PILS., Proc. A. N. S. Phila. 1899, p. 396; 

 1903, p. 772, pi. 47, f. 5, 5a. 



Euglandina dalli belongs to a small group of Mexican 

 species of small size and smooth, glossy surface, but seems 

 abundantly distinct from any hitherto described. Compared
