Dimensions: Alt. of body whorl, including canal, 40; width, 31; 

 longest diameter of aperture, 33; transverse diameter, 18. 



This variety is distinguishable from P. lapillus var. saxicola^ 

 by a less gibbous body whorl, by a smaller and more elongated 

 aperture and by the canal being more extended and turned more 

 backwards. 



A single specimen was obtained from the Pliocene of the Quil- 

 layute formation at the old mouth of Maxfield creek, near Quilla- 

 yute, Wash. 



Suborder Streptodonta; Superfamily Gymnoglossa. 

 Family LXIII Eulimid^e; Genus Eulima Risso. 



Shell small, white, and polished; slender, elongated, with numer- 

 ous level whorls; spire often curved to one side; obscurely marked 

 on one side by a series of periodic mouths which form prominent 

 ribs internally; apex acute; aperture oval, pointed above; outer lip 

 thickened internally; inner lip reflected over the pillar, not um- 

 bilicated (Arnold). A characteristic species is Eulima tortuosa 



Adams. 



60. Eulimna washingtoni n. s. Plate VI, fig. 60. 



Shell small, elongated, not curved to one side, thin; spire very 

 acute; whorls six to ten; suture distinct, impressed; aperture elon- 

 gate-ovate; outer lip thin, rather arcuate. 



Dimensions: Axial length of medium-sized specimen, 12; lat., 3. 



This species differs from K micans Carpenter in having its 

 suture impressed. 



It is a rare species in the Quillayute formation of Quillayute, 



Wash. 



61. Eulima smithi n. s. Plate VI, fig. 61. 



^heW resembling Eulima washingtoni a.hoYe,huth.8iving rounder 

 shoulders shown on the cases. 



Superfamily T.ENio^iLOSSA; Family LXV Tritonid.?!^. 

 Genus Ranella Lamarck. 



Shell with elongated spire, compressed, with two opposite varices 



which are continuous over all the whorls; aperture oval; canal 



short, recurved; outer lip crenulated; columella arcuated and crenu- 



lated or ridged. Ranella spinosa Lam. is a characteristic species. 



62. Ranella marshallii n. s. Plate VI, fig. 62. 



Shell lar.'^e, broadly fusiform; spire elevated; whorls convex, each 

 with two J rominent, oppositely placed, rounded, rather reflexed 

 varices, each forming a continuous varix from apex to base of shell: 

 suture deeply impressed, distinct: aperture suboval; outer lip
