Extract

In 1881 Mr. J. W. Davis proposed the genus Anodontacanthus for certain straight spines resembling Pleuracanthus, but differing in the absence of the two rows of denticles. Three species are included:–A. acutus and oltusus, from the Coal-measures of Yorkshire, and A. fastigiatus, from the Blackband Ironstone of Carboniferous Limestone age at Loanhead, near Edinburgh.

page 102 note 2 My friend Mr. A. Smith Woodward writes to me that he has, from an examination of specimens from Derbyshire, come to the conclusion that Pristodus Bmniei (R. Eth., jun.) is after all distinct specifically from P. falcatus, Ag. Concinnus (Davis) he also is inclined to regard as distinct, and in that case all three names will stand as species of Pristodus.
