Tyrieocrinus (gen. nov.) and Scotiacrinus (gen. nov.) and Seven New Species of Inadunate Crinoids from the Carboniferous Limestones of Scotland and Yorkshire.

Published online by Cambridge University Press:  01 May 2009

Extract

The majority of the Scottish specimens described in this paper consist of cups only, and have been in my collection for a long time. In earlier days they would probably have been assigned to genera like Poteriocrinites and Pachylocrinus, but in recent years great additions have been made to our knowledge of Carboniferous inadunate crinoids by American workers such as Kirk, Moore, Laudon, Strimple, and others. New genera and species have been created, many of them based on all the characters of complete crowns. Obviously, when dealing with cups alone, it is not always easy to trace exact relationship to such perfect examples of crinoid life. It seems evident, however, that the cups here dealt with differ in certain ways from forms so far described, and an attempt is now made to give them specific standing. Four new species are ascribed to known genera, three, including two new species, to the new genus Scotiacrinus, and one to a new Cromyocrinid genus for which the name Tyrieocrinus is proposed. A revision is also given of the species previously described as Erisocrinus scoticus (Wright, 1942, pp. 275–6) and now referred with reservations to Apographiocrinus Moore & Plummer. I wish here to thank Dr. A. C. Stephen, of the Royal Scottish Museum, for the loan of a specimen belonging to that institution, now named Scotiacrinus yoredalensis, and the authorities of the Museum for permission to describe and figure it.
