538 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxii. 



subequidistant raised lines, of much less prominence than the lonj^i- 

 tudinal ridges. Suture appressed, distinct, and only slightly wavy. 

 Aperture ovate; outer lip thickened; cohunellar lip incrusted. Colu- 

 mella slightly twisted, faintly spirally sculptured, and with groove 

 next to body whorl. Canal short. 



Dimensions. — Longitude, 15 mm,; latitude, 9 mm. 



Notes. — This species is unlike an}^ other West Coast form, being 

 characterized b}^ its blunt apical whorls, convex whorls, deep suture 

 and sharp naiTow longitudinal ridges. The type has a glossy surface. 

 Named in honor of Mr. Homer Hamlin, city engineer of Los Angeles, 

 California, to whom we are indebted for preserving the valuable 

 paleontological material taken out of the Third Street tunnel, Los 

 Angeles. 



2ype.—C2^t. No. 164946, U.S.N. M. 



Locality. — Third Street tunnel, Los Angeles, California. (Homer 

 Hamlin.) 



Heyrizon. — Lower Pliocene, probably middle Fernando formation. 



CYPR^A FERNANDOENSIS, new species. 



Plate L, fig8. 8 and 8". 



Descr'qition.— '^V^W about 40 mm. in length, pyriform, ventricose, 

 convolute; spire concealed; surface covered with brown enamel, some 

 of which is retained; aperture long and narrow, with a canal at each 

 end, the anterior canal being the longer; outer lip inflected and 

 crenulated with about seventeen teeth; inner lip similarly crenuhited. 



Dimensions. — Longitude, 40 mm.; latitude, 24 mm. 



Notes. — This species, which is doubtless the precursor of C. spadicea 

 Graj^, is relatively broader, has a relatively broader and less protruding- 

 anterior portion to the outer lip, has a relativel}^ broader and more 

 nearl}^ straight aperture, fewer teeth, and has these teeth, especially 

 those on the anterior portion of the inner lip, more evenly spaced, 

 than in C. spadicea. Named for the Fernando formation, of which 

 it is supposed to be characteristic.
