[98] Sir C. Lyell remarks that this is apparently the B. Uddevallensis (Linn.) of Swedish lists of fossils. Prof. E. Forbes has shown (Mem. Geolog. Survey of England, vol. 1, p. 364) how this name arose, from a short description, prior to the introduction of the binomial system, “Lepas quæ Balanus Uddevallensis,” given by Linnæus in his Wast-Gotha Resa, in 1747.

For the reference to Ascanius’ work, which is on the binomial system, and subsequent to the 10th edit. of Linnæus, in 1758, I am greatly indebted to Mr. Sylvanus Hanley. Had it not been for this gentleman, I should have used Müller’s name of B. tulipa as the first name.

Shell white: radii with their oblique summits smooth and arched; sutural edges smooth: basis solid. Scutum feebly striated longitudinally: tergum with the spur narrow.
