Dimensions. — Length of nearly perfect specimen, 24 mm. ; width of 

 body-whorl, 7 mm. ; length of spire, 10 mm. 



Occurrence. — University of California Locality 1853. 



MONODONTA WATTSI, n. sp. 

 Plate 40, figures 3a, 3b 



Turbinate, with five convex whorls ; the first two are smooth ; the 

 remaining whorls are decorated by slightly nodose spiral lines. A 

 fairly well developed collar with spiral threads upon it is found on 

 the body-whorl just below the linear suture. The threads upon this 

 collar and upon the base are finer than those of the central portion 

 of the whorls. Outer lip simple ; inner lip thinly callused ; a single 

 tooth characteristic of the genus is found upon the columella. 



This species is also found in the Tejon at California Academy of 

 Sciences Locality 240, near Vader, Washington. 



Named in honor of Mr. W. L. Watts who first collected at this 

 locality. 



Dimensions. — Length, 6 mm. ; width of body whorl, 7 mm. 

 Occurrence. — University of California Locality 1853. 



METULA HARRISI, n. sp. 

 Plate 42, figure 1 



Shell elongate fusiform, with spire about as long as the body- 

 whorl. Whorls are seven or eight in number, the two upper ones 

 being lost. The last three whorls are cancellated by one or two long, 

 rounded varices. The body-whorl and the two preceding whorls are 

 decorated by axial ribs and spiral lines of equal strength, giving the 

 shell a reticulated appearance. Outer lip thickened ; inner lip covered 

 by a thin, long callus ; canal short, slightly twisted. 



This form is very similar to M. sylvaerupis Harris of the Lignitic 

 Stage of the Gulf Coast Eocene. It appears to differ from M. 

 sylvaerupis in its lack of ' ' one or two comparatively large spiral lines 

 on the humeral slope." 



Named in honor of Professor G. D. Harris of Cornell University, 

 whose standard works on the Eocene of the Gulf Coast have been of 

 great service to the writer. 



Dimensions. — Length of broken specimen, 17 mm.; width of body- 

 whorl, 6 mm. 



Occurrence. — University of California Locality 1817.
