MARINE SHELLS OF WEST COAST OF NORTH AMERICA 
Genus DAPHNELLA Hinds, 1844 
Shell fusiform, thin, fragile, usually striated; aperture elongated oval, 
canal very short. Small and elegant shells of slight thickness, distin¬ 
guished from Defrancia by their elongated body-whorl, tenuity and sculp¬ 
ture. No operculum. (Tryon, Structural and Systematic Conchology .) 
Type. Daphnella limnaeiformis Kiener. 
Distribution. California to Gulf of California. 
Daphnella fuscoligata Dali, 1871 
American Journal of Conchology, 7:100. Tryon, Manual of Conchology, 6; PI. 34, 
fig. 95. 
Shell fusiform, slender, solid, of four or five whorls; spire half as 
long as the shell, aperture the same; the latter narrow, with no perceptible 
sinus, and a short open canal; columella and outer lip smooth; sculpture 
consisting of strong, revolving, elevated lines, six on the last whorl, 
crossed by strong, regular, longitudinal costae of about the same size, 
twelve on the last whorl. These ridges are remarkably uniform, and 
their intersections produce a very conspicuously regular reticulation. 
The longitudinal ridges are, perhaps, a little thicker on the convexity of 
the whorls than above and below. General coloration white, with a 
reddish-brown band between the suture and the first revolving ridge, 
another between and including the third and fourth ridges, the other 
revolving ridges being dotted with brown between their intersections 
with the costae. These intersections, especially on the last whorl, appear 
somewhat nodulous. Long., .29; lat., .13 inch. (Dali.) 
Type in United States National Museum. Type locality, Monterey, 
California. 
Range. Monterey to San Diego, California. 
Daphnella clathrata Gabb, 1865 
Proceedings of the California Academy of Sciences, 3: 185. 
D. t. parva, fusiformis, tenuis; anfra. iii. nucleosis, laevibus; anfra. 
normalibus iii.+ supra oblique truncatis; superficie confertim clathrata; 
striis radiantibus obsoletis circa basim; apertura magna; columella parum 
tortuosa; labio parum incressato; labio acuto; sinu postico sub-profundo, 
supra acuto, ad suturam attingente; colore albido, sparsim brunuco punc- 
tato. Long., .37; lat., .14; long, aper., .22. (Gabb.) 
Shell small, fusiform, thin, aperture longer than the spire; nuclear 
whorls three, smooth: normal whorls three or more, obliquely truncated 
above, convex below, this truncation is partially obsolete on the last
