tracum gray, thick, opaque, closely striate 
transversely. In life, visible portions of foot 
and siphon bright lemon yellow. 
length: 70 mm. 
TYPE locality: Indian Ocean. 
REMARKS: Small specimens of this species 
closely resemble C. litoglyphus. C. vitulinus may 
be distinguished by having striae above the 
central band, rows of brown dots on the 
white bands, and absence of a pointed apex. 
C. vitulinus is a relatively uncommon spe- 
cies on Hawaiian reefs. It is known to occur 
to a depth of 30 fathoms. Pleistocene fossils 
are known from Molokai (Ostergaard, 1939). 
A single specimen labeled Conus planorbis 
Born in the collection of the B. P. Bishop 
Museum (No. 68990) was dredged in Hono- 
lulu Harbor, The Museum of Comparative 
Zoology contains another specimen (No. 
146332) collected at Midway Island by J. 
Chalean, apparently alive when collected. 
These specimens are extremely similar to, and 
may be synonymous with, C. vitulinus, as has 
been suggested by some workers (p. 395).

Icon. Coq. Viv., 2: pi. 99, fig. 3, p. 225. 
DESCRIPTION: Shell subcylindrical; maxi- 
mum diameter slightly more than one half 
the length. Body whorl obsoletely striate, the 
striae slightly more pronounced and as raised 
ridges toward the base. Aperture rather broad, 
flaring slightly basally. Shoulder smooth, 
rounded. Spire moderately elevated, obtuse, 
straight or slightly convex, obsoletely striate. 
Color dark reddish brown, as many closely 
spaced and intersecting longitudinal lines 
separated by small white spots; occasionally 
with larger white subtrigonal blotches as in

Oahu. Photograph by C. E. Cutress. 
C. pennaceus; two broad transverse bands 
either side of the center appear to be super- 
imposed on this pattern. These bands are 
more solidly colored and are similar to the 
reddish brown areas of C. pennaceus in that 
they bear narrow transverse closely spaced 
lines finely dotted with white. Color pattern 
of the spire similar to that of the bands on the 
body whorl. Interior of aperture bluish white. 
length: Specimens in the U. S. National 
Museum and Academy of Natural Sciences of 
Philadelphia range from 15.5 mm. to 27 mm. 
in shell length. The specimen illustrated in 
Figure 3 measures 35 X 19 mm. 
TYPE locality: None. 
REMARKS: Conus elisae was first reported 
from Hawaii by Weinkauff (1874). Recently, 
a number of specimens agreeing with the 
description and figure of this species have 
been collected on the islands of Kauai and 
Niihau. Sowerby (1858: 43) considered this 
species to be synonymous with C. pennaceus, 
a conclusion with which the present writer 
has been inclined to agree. However, no 
specimens intermediate in character between
