Herbstia (Herbstiella) camptacantha Holmes, Occas. Papers California Acad. Sci., vol. 7, 1900, p. 37 (part).—Rathbun (not Stimpson), Proc. U. S. Nat. Mus., vol. 16, 1893, p. 79 (part). Diagnosis.—Palm armed with spines or spinules at the proximal end of its upper margin. Two spines on outer margin of basal antennal article, including that at anterior angle; first movable article falling short of tip of rostrum. Description.—The descrip- tion given by Stimpson for Herbstiella camptacantha ap- plies very well to the Cali- fornian species here called parvifrons except that in place of two of the dorsal branchial tubercles there are spines; spines of arm more numerous than in camptacantha and in two adjacent and irregular rows, 12 or 13 in the outer- most row, 5 or 6 in the other row, 2 spines on inner margin just distad of the middle; Fig. 99.—Herb
