In a paper published in the Geological Magazine last year (LXXIII, 385–112), it was mentioned that in my collection of Scottish Carboniferous crinoids there remained ten or eleven species to be described. In the present paper eleven species are dealt with, but I find this does not complete the list since there are still a few others, including species of Hydreionocrinus, Eupachycrinus, etc., and some very minute forms belonging to unknown genera which require further elucidation. It is my hope later on to describe these along with a revision of the Scottish Carboniferous crinoids as a whole. Meanwhile, on another page is given a list of all the species known to date so that a comparison can be made with the faunas of other regions. Here, I wish to add to the list of species already given from Coplow Knoll, Clitheroe (C1) (Geol. Mag., 1935, LXXII, p. 205), the following species: Platycrinus coronatus Goldfuss, Dichocrinus sp., Symbathocrinus conicus Phillips, and Mespilocrinus forbesianus de Koninck & Le Hon.

One of the first authors to note the Ardross fauna was the Rev. T. Brown (1861, pp. 394–5), who “detected small scales of some species of Palaeoniscus, and a good specimen of an Amblypterus, which seemed to be the A. striatus. There were teeth and scales also of a Holoptychius; and their resemblance to the figure of the H. portlocki … seemed to be complete”.

The fauna was summarized by Peach (1902, pp. 357–375), who, in addition to two plants, four arthropods, five brachiopods, and six lamellibranchs, gave the following list of fishes:—
