List of Shells collected at Santa Barbara and San Diego by Mr. J. Hepburn, in February-March, 1866.

WITH REMARKS UPON SOME OF THE SPECIES,
BY ROBT. E. C. STEARNS, CURATOR OF CONCHOLOGY, CAL. ACAD. NAT. SCIENCES.

Through the kindness of Mr. Hepburn, well known as an enthusiastic and intelligent collector, I have been permitted to examine the collections made by him at the localities referred to, from which I have compiled the following list.

The remarks in connection with a few of the species are not wholly based upon the specimens obtained by Mr. Hepburn, but rather upon specimens received by me from various sources, and forming a portion of my private collection.

The figures in the left hand column refer to the numbers in Mr. P. P. Carpenter’s Supplementary Report (1863) to the British Association.

REMARKS.

269. Leptothyra sanguinea, Carp. Common at Monterey; all shades of color from light red to very dark purple; sometimes broadly banded with white; another variety is marked with irregular whitish streaks, causing a resemblance to the young shells of 282, Omphalius fuscescens.

275. Trochiscus Norrisii, Sby. The apex whorls of the young shells have a spiral band tesselated with white and red.

388. Conus Californicus, Hds. When young, the shells of this species are ornamented with yellowish brown markings upon a light bluish ground.

A Surcula Carpenteriana, Gabb. The most perfect recent specimen of this rare species that I have seen (described by Mr. Gabb in Vol. III, Cal. Acad. Pro. p. 183) was obtained by Mr. Hepburn; when perfect, one of the finest shells of the upper Californian province; the specimen referred to is of a clear light salmon color, traversed spirally by narrow bands or broad lines of reddish brown, and resembling in its general coloring that equally fine shell Narona Cooperi, Gabb, described as above, p. 186.

460d. Purpura var. ostrina, Gld. Deposits its yellowish eggs on the rocks at Black Point and the Cliff House near San Francisco, in the latter part of June (1865) and the middle of July (1866).

75. Pachydesma crassatelloides, Conr. Valves frequently marked with broad radiating bands of light brown.

266. Pomaulax undosus, Wood. Young shells approach closely to the immature form of Pachypoma gibberosum, Chemn.

281. Mr. Carpenter remarks in his supplementary Report to the B. A., in connection with Chlorostoma aureotinctum, Fbs.: “mouth orange spotted.” I should amend this so as to read umbilicus stained with orange.

456. Amphissa corrugata, Rve. This species assumes nearly every shade of color and an innumerable variety of markings; the latter being generally some shade of brown upon a lighter colored ground.

74. Amiantis callosa, Conr. An aberrant form of this species in my collection suggests, in outline, Dosinia.

88. Saxidomus aratus, Gld. A single specimen of a young shell of this species (Coll. Stearns) is prettily marked with brown upon the posterior dorsal portion of the valves.
