then it would seem that this variety might be listed. My speci- 
mens were received from Mr. Henry Hemphill, that Master of 
Variations in Mollusca. Dr. Yates lists this var. in Bull. Santa 
Barbara Soc. Nat. Hist., page 44. Cooper’s Geog. Cat. gives its 
locality ‘‘Neah Bay to San Diego.’’ 
MURICIDA 
Genus Murex Linné 
Murex californicus Hds. 
Dredged 14 fathoms Pt. Fermin by Mr. Hubert Lowe, T. I. 
This white shell was labelled P. trialatus Sby., but not satis- 
- factorily so, in my collection. Mr. Button pronounced it the 
above species. Trvon’s Man. Conch., Vol. 11, page 113, plates 
34 and 35, figs. 375 and 287. Dr. Dall in The Nautilus, Vol. XIV. 
page 38. 
Genus Ocinebra Leach 
Murex (Ocinebra) circumtexta var. aurantia Stearns. 
San Pedro Bay, Cal. 
This color var. of Dr. R. E. C. Stearns’ species is described 
by him on page 16 of The Nautilus, Vol IX, as having bands of 
a ‘‘deeper orange’’ than the color of the shell. In typical forms 
ofcircumtexta these bands are ‘‘dark, sometimes almost black.’’ 
My specimen was collected by Mrs. E. A. Lawrence in 1897.

Monterey Bay from Fred L. Button, Esq. : 
This var. is described, with synonomy, by Dr. Ralph Arnold

207, plate V, fig. 12. In Dr. J. G. Cooper’s Cat. Cal. Fos. 1888 
(7th Ann. Rep’t. S. Min. Bu. for 1887), he makes this variety 
a synonym for lurida and in his label List, ‘‘Cat. W. North 
Amer. and Many Foreign Shells’’ he omits it. Dr. Lorenzo G. 
gates lists this var. from Santa Barbara Channel (Bul. Santa 
Barbara Soc. Nat. Hist.).
