NO. 1704. A COLLECTIOX OF f^RELLSi FROM PERV—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 ])illar; 

 interior with the coloration shining through the shell and a faint 

 grayish enamel; umbilicus small, deep; sculpture of incremental 

 lines 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 slight 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, Zool. Beechey's Voy. p. 119, (pi. 33, fig. 2, 1839, as C. 

 interruptus Broderip and Sowerby, Zool. Journ., vol. 4, p. 379, 1829; not C. 



interruptus Maw E, Conch., 1828). 



Dredged in wSechura 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 veiy shal- 

 low channel behind the suture, but is not spii'ally 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. 



Plate 23, fig. 4. 



Oliva peruviana Lamarck, Ann. du Museum, vol. 16, 1810, p. 317; Encycl. Meth. 

 pi. 364, fig. 3. 

 Dredged, living, in Sechura Bay, between Bayovar and Matacaballa. 



Distribution. — From 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.
