Family LXIII. EULIMID.E. 



Genus Eulima Risso. 



Shell small, white, and polished; slender, elongated with numerous level whorls; spire often 

 curved to one side; obscurely marked on one side by a series of periodic mouths which form promi- 

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

 lip reflected over the pillar, not umbi Heated. 



Eulima tortuosa Adams is a characteristic species.

Eulima falcata Cpr., Proc. Zool. Soc, 1865, p. 280. 



Shell small, elongated, thin, white, glossy; spire verj' acute, curved into scythe-shape; 

 whorls ten, flat; suture indistinct, not impressed; body-whorl subangular at base; base elongated; 

 aperture pyriform, seemingly appressed to side of shell out of its normal position; outer lip acute and 

 rounding; inner lip concave. 



Ditnensions. — Long. 6.5 mm.; lat. 3 mm.; body-whorl 3 mm.; aperture 2.5 mm.; defl. 

 30 degrees. 



Distinguishable from E. jnicans by subangulated body-wliorl, eccentric nperture 

 and curved spire; distinguishable from E. hastnta by curved spire and more eccentric 

 aperture. The specimens described were identified by Dr. Dall. 



One specimen each from the lower San Pedro series at Deadman Island and 

 the upper 8an Pedro series at San Pedro. The specimen figured is from the lower 

 San Pedro series at Deadman Island, and is now in the collection of Delos Arnold. 



Living. — Acapulco (Carpenter) . 



Pleistocene. — San Pedro (Oldroyd; Arnold).

Distinguishable by the short, angular base, and short, truncated aperture. In 

 other respects like E. micans. Specimens identified by Dr. Dall. 



Four found in upper San Pedro series at San Pedro; and one in the lower 

 San Pedro series at Deadman Island. Found in the Pleistocene at Barlow's ranch,
