than the crenulations at the summit of the whorls. Base moderately 

 long, well rounded, provided with a strong fasciole at the anterior 

 end and marked by rather strong incremental lines and very fine 

 spiral striations. Aperture oval, posterior angle acute, outer lip 

 thin, showing four denticles within, of which the median two are the 

 strongest; inner lip thick, almost straight, provided with three folds, 

 of which the first is lamellar and almost transversely disposed; it 

 covers the posterior portion of the basal fasciole ; the other two folds 

 are much Aveaker and much more obliquely placed and extend to the 

 anterior portion of the columella; parietal wall glazed with a thin 

 callus. 



The type, Cat. No. 268628, U.S.N.M., was dredged by the U. S. 

 Bureau of Fisheries steamer Albatross at station 5628, off Redondo 

 Point, ISIagdalena Bay, Lower California, in 13| fathoms, on broken 

 shell bottom. It has 9 postnuclear whorls and measures — length, 5.8 

 mm. ; diameter, 2.1 mm. 



This species is nearest related to Pyramidella {Longchaeus) mazat- 

 Janica Dall and Bartsch, but can readily be distinguished from it by 

 the fact that the whorls are not overhanging. 



EULIMELLA GABBIANA Anderson and Martin.

This is a typical Melanella {Eulimella) and does not belong to the 

 Pyramidellidae, but to the related family, Melanellidae. The name 

 will therefore have to be changed to Melanella gahljiana Anderson 

 and Martin. The type No. 143 California Academy of Sciences comes 

 from the Lower Miocene, in the bottom of a small canyon about 1| 

 miles due north of Barker's ranch house, Kern River, Kern County, 

 California. 



PYRAMIDELLA (SYRNOLA) OCHSNERI Anderson and Martin.

Anderson and Martin described this species which they collected 

 in the Lower Miocene in the bottom of a small canyon about 1| miles 

 due north of Barker's ranch house, Kern County, California, locality 

 64. They give a rather incomplete description and state that the 

 type, which has a broken apex, is 8 mm. long and 3 mm. in diameter. 



From the brief description and the figure I am inclined to believe 

 that it is not a Eulimella, but belongs to the subgenus Syrnola. A 

 comparative statement in the same publication (p. 67) under EiiU- 

 mella dilleri strengthens this belief. The type. No. 138, and cotype, 

 No. 139, are in the California xA.cademy of Sciences.
