IX.—Additional Note on Loricula

Abstract

Since the appearance of my paper on Loricula Darwini in the November Number of this Magazine (pp. 491–9) my attention has been called by Mr. C. D. Sherborn to two American Loriculæ described by W. N. Logan, “On some new Cirriped Crustaceans from the Niobrara Cretaceous of Kansas,” U.S.A., published in the Kansas University Quarterly (series A, October, 1897, vol. vi, No. iv, pp. 187–9, 8vo) and in the University Geological Survey of Kansas (vol. iv (Paleontology), pt. viii, 4to, Arthropoda, pp. 498–501, pi. cxi) under the names of Stramentum haworthii, Williston, type-specimen figured much enlarged, and S. tabulatum, Logan. The other two species on p1. ex, figs. 3–5, of the same work, described under the name of Squama spissa and S. lata, Logan, are quite distinct from Loricula, but are said to have been found adhering to a fragment of shell of Inoceramus by their entire length. The arrangement of the capitulum and peduncle differ very widely from those of Loricula and resemble Pollicipes.
