248 TERRESTRIAL AIR-BREATHING MOLLUSKS. 



process on the tail, reminding one of the caudal process in some of tbe genera 

 of disintegrated Nanina. 1 



Hemphillia glandulosa. 



Animal from 1 2 to 30 millimetres long (preserved in alcohol) ; color smoky 

 white, mottled with longitudinal, dark brown blotches, running obliquely from 

 the edge of the mantle to the foot, uniformly with the coarse granulations, of 

 which there are about twenty-five on either side of the animal. Caudal process 

 very large, triangular in profile, dark brown, with a few coarse granulations. 



Shell unguiform, slightly convex, light horn-color, very thin, its edges almost 

 membranous, with prominent concentric lines of growth ; 5 mill, long, 3 mill, 

 wide in a specimen of twelve mill, length (Fig. 145).

Astoria, Oregon, in the Oregonian Region. 



The description is drawn from specimens preserved in alcohol, due allow- 

 ance for which fact must be made. They were collected at Astoria, Oregon, 

 oy Mr. Henry Hemphill, to whom Mr. Bland and myself dedicated the genus 

 in return for most valuable addition to our knowledge of the land shells of the 

 Pacific Coast. 



Jaw thick, low, wide, slightly arcuate, ends attenuated, blunt ; cutting margin 

 without median projection; anterior surface with about'14 crowded, stout, 

 irregularly developed ribs, denticulating either margin (Fig. 146). 



Lingual membrane (PI. V. Fig. J) long and narrow. Teeth 23 — 1 — 23, 

 with 11 perfect laterals. Centrals with a quadrangular base of attachment, 

 higher than wide. Reflection about half as long as this base, with a long, 

 narrow median cusp reaching the lower margin of the base of attachment, 

 beyond which projects slightly the short cutting point; side cusps but little 

 developed, but bearing short, stout triangular cutting points. Laterals like the 

 centrals, but asymmetrical by the suppression of the inner, lower, lateral 

 ano-le of the base of attachment, and the inner side cutting point. First mar- 

 ginal (b) with a square base of attachment, broadly reflected into a stout 

 cusp, bearing an inner, stout, very long, bluntly ending, oblique cutting point, 

 and a small outer cutting point. Outer marginals (c) low, wide, the reflection 

 broad, reaching the lower edge of the base of attachment, and bearing one 

 inner, long, oblique, blunt cutting point, and a small outer cutting point. 



The genitalia are figured (PI. XU. Figs. J, K). The testicle is composed 

 of a large globular mass of aciniform casca. It lies loosely upon, not imbedded 

 in, the upper lobes of the liver. The ovary and oviduct are as usual. The 



l Mr. Hemphill informs me that in the living animal this hump-like process is less 

 conspicuous than in specimens preserved in alcohol. The shell is central, and much 

 broader than the animal when in motion.
