no. 1704. A COLLECTION OF SHELLS FROM PERU—DALL. 165 
an apical dimple and about a whorl and a half; spire above the last 
whorl about one-third of the total length or even less; color lilac- 
gray, with retractive axial streaks, more or less irregular, of purplish 
brown; aperture ovate, with a sharp simple peristome, a wash of 
enamel on the body, and a straight, thin, hardly reflected pillar; 
interior with the coloration shining through the shell and a faint 
‘grayish enamel; umbilicus small, deep; sculpture of incremental 
Imes and feeble irregular rugosities. The type (Cat. No. 207700, 
U.S.N.M.) measures: Height of shell 27; of last whorl 19; of aperture 
13.5; maximum diameter of last whorl 15 mm. 
This species is most nearly approached by B. apodematus Orbigny, 
but differs constantly in its depressed spire with deep sutures, the 
very shght masking of the umbilicus by the expansion of the pillar, 
the aperture slightly more angular at the base, and the deeper and 
more intense coloration. It is named for the collector of the 
specimens. 
CONUS XIMENES Gray. 
Conus ximenes GRay, Zoél. Beechey’s Voy. p. 119, (pl. 33, fig. 2, 1839, as C. 
interruptus BRODERIP and SowERBY, Zool. Journ., vol. 4, p. 379, 1829; not C. 
interruptus MAwe, Conch., 1828). 
Dredged in Sechura Bay, halfway between Bayovar and Mataca- 
balla. One dead specimen. 
This is the original interruptus of Broderip and Sowerby, as figured 
in Beechey’s voyage. The normal C. Ximenes, as described, has 
additional brown flammules, this variety only the spiral rows of 
brown dots on a greenish-white ground. The spire has a very shal- 
low channel behind the suture, but is not spirally striated like C. 
purpurascens, or granulated anteriorly as in that species. The shell 
is covered with a velvety periostracum, while that of C. purpurascens 
is smooth and almost polished.

Oliva peruviana LAMARCK, Ann. du Muséum, vol. 16, 1810, p. 317; Encycl. Méth. 
pl. 364, fig. 3. , 
Dredged, living, in Sechura Bay, between Bayovar and Matacaballa. 
Distribution.—F rom Valparaiso, Chile, northward to Guayaquil 
and the Galapagos Islands. 
Shell ovate, solid, polished, whitish with irregular brown stripes, 
sometimes angular, sometimes axially directed. The epipodia 
behind, from the preserved specimens, seem to form a sort of pocket, 
which in life should fit over the spire of the shell.
