irregular distribution of the nodes and by the smaller number of 

 of nodes. 



The figured specimen was obtained from the type locality in Rose 

 Canon, University of California Locality 2226. 



FASCIOLARIA BILINEATA, n. sp. 

 Plate 37, figures 6a, 6b 



Shell fusiform with moderately long, narrow canal ; seven or eight 

 whorls. The first three nuclear whorls, smooth. The last four or 

 five whorls are decorated by two very strong spiral lines, the upper 

 one of which marks a very prominent shoulder on the whorls of 

 mature specimens. These spiral lines are crossed by eight to ten axial 

 ribs which extend from suture to suture. The space between the wavy 

 suture and the shoulder is covered by fine spiral threads ; outer lip 

 crenulate ; inner lip with three oblique plaits. 



The younger specimens do not show the shouldering on the whorls 

 but have rounded whorls instead. The number of whorls was ob- 

 tained from a study of a young specimen. 



Dimensions. — Height of broken type, 15 mm. ; width of body- 

 whorl, 9 mm. 



Occurrence. — The type specimen was obtained from the Tejon of 

 Rose Canon, San Diego County, California, University of California 

 Locality 2226. 



FUSINUS MERRIAMI, n. sp. 

 Plate 40, figures 2a, 2b 



Shell with long, acuminate spire and with long, straight, narrow 

 canal ; whorls, eleven in number ; the first two rounded ; the other 

 whorls are angulated at a point about two-thirds of a whorl-length 

 below the suture. The last nine whorls have the angle marked by 

 ten flat pointed nodes which are decidedly upturned on the body- 

 whorl. The space above the angle of a whorl is decorated by seven 

 to ten spiral lines and by five growth lines of about the same strength. 

 Below the angle are found three or four spiral lines which alternate in 

 size. The decoration on the body-whorl is similar to that of the spire- 

 whorls. The spiral lines below the angle on the body-whorl are eight 

 in number. 



Named in honor of Professor J. C. Merriam, whose kindly criticism 

 has been of great service in the preparation of this paper.
