From venusta and citrina, Mighels, it varies both in form and color. With some varieties of picta it claims analogy only in the general plan of painting. Its striking characteristics are its blunt apex, slightly rounded whorls, small aperture, short and white columella, umbilicus, and general plan of coloring.
A few specimens were collected at an elevation of 7,500 feet, on West Maui, by the Rev. M. Alexander, to whom the species is dedicated.
Description of New Species of Marine Shells from the Coast of California.
BY WM. M. GABB.
The following are a few of the shells collected by Dr. J. G. Cooper, of the State Geological Survey, during his explorations along the coast of this State. The specimens are preserved in the collection of the Survey; most of them appear to be very rare in a living state, though I have encountered several of them in the later Tertiary deposits, especially in the Post Pliocene.
