THE GEOLOGIST, 



Abstract 0/ a Notice of a new Genus or Crinoides, read before 

 Section C. of the British Association for the advancement of Science, 

 at Dublin, August 27th, 1857, Presented by Professor L. de Konimhr 

 F. G. S., of Liege ; and Edward Wood, Esq.y F. G. S., of Richmond., 

 Yorkshire. 



In the year 1854, when the Genus Woodocrinus was first described, 

 a single species only had been found. Indications of others were 

 impressed u-pon the slabs, the surfaces of which were almost com- 

 posed of the remains of the Crinoides. During the last three years 

 great exertions have been made to discover all the fossils that this 

 bed contains — and the gratifying result has been, that four or 

 five new species have been added to that which was the type of 

 the genus which Professor de Koninck described in a paper read 

 before the Royal Society at Bmssels, and figured in his work on 

 the Carboniferous Crinoides. 



The thin bed in which they have been found is of very 

 limited area, being known in the district as the * Red bed ' of the 

 Lead Miners, and is about the middle of the Yoredale Rocks of 

 Professor Phillips's * Mountain Limestone Geolog}^ of Yorkshire.' 

 The strata below and above it appear to be unfossiliferous. Its 

 locaHty the Carboniferous Rocks on a moor in Swaledale, near 

 Richmond, in Yorkshii-e. 



These Crinoides are associated with the teeth of Petalodus 

 Hastmgii ; and not the slightest trace of any other fossil has yet 

 been found with them. They he in the bed a confused mass of 

 stems, calices and arms, twisted and interlaced in such a manner 

 as would lead to the idea that they are the stranded remains of 

 these creatures, torn from their beds, or driven from the zone of 

 water where they lived; and that the locality in which they are 

 fomid was not that which they inhabited. However that may be, 

 the ocean, of which they were denizens, swarmed with them. 



The newly-discovered species are by no means less interesting 

 than that which was the first described, and tliey offer some 

 pecuUarities which tend to modify and to complete the character 

 which has been assigned to the genus.
