Boulder Creek, and locality No. 117, on the East Fork of the North 
Fork of Waddell Creek, in the Big Basin (R. Arnold); also found 
in the Oligocene at Porter, Washington (U. 8S. Geological Survey, 
locality Ne. 4063).

FUSUS HECOXI, new species. 
> Plate XXXXIII, fig. 8. 
Description.—Shell about 50 mm. in length, slender, fusiform; apex 
acute. Whorls 6 or 7, moderately angulated, concave above angle, 
slightly convex below; an almost obsolete narrow revolving band 
marks the upper margin of the whorl; 10 regularly rounded shghtly 
oblique nodes surmount the angle and become obsolete a short distance 
both above and below it; the obliquity of the nodes is in a direction 
sloping downward toward the left; whole surface sculptured by 
alternating major and minor narrow, raised, revolving lines and oc- 
easionally by obsolete microscopic revolving strive; suture appressed, 
distinct. : ; 
Dimensions.—Of imperfect type, length, 36 mm.; latitude, 18 mm. ; 
apical angle, 40°. 
Notes.—A large specimen believed to be of this species from locality 
No. 105, on Love Creek, shows 2 instead of 1 minor lines between 
some of the major revolving ones; this large specimen measures 25 
mm. in width. /. hecoxi is closely related to FY. sanctecrusis, but 
may be distinguished from the latter by its greater size, relatively 
broader spire, nodose rather than axially ribbed whorls, and by the 
alternating character of its spiral lines. Like /. sanctecrusis, F. 
hecoxi 1s allied to #. gentculus Conrad from the Oligocene of Oregon, 
but may be distinguished from the last by the greater angularity of 
its whorls, by the concave outline of the upper portion of the whorl, 
by its nodose rather than axially ridged sculpture, and by the coarser 
character of its revolving lines. F’. hecoxi also resembles Priscofusus 
medialis Conrad from Astoria, but is slenderer, has larger, broader 
nodes and much more prominent spiral sculpture. 
Named in honor of Miss Laura J. F. Hecox, United States light- 
house keeper, Santa Cruz, whose collection of specimens and interest 
in natural history has been an inspiration to all who have had the 
pleasure of her acquaintance.
