THE GEOLOGIST. 
Abstract of a Notice of a new Genus of Crinoides, read before 
Section C. of the British Aasociation for the advancement of Science, 
at Dublin, August 27lh, 1857. Presented by Professor L. de Koninclc, 
I F. G. S., of Liege ; and Edward Wood, Esq., F. O. S., of Richmond, 
Yorkshire. 
In the year 1854, when the Geuus Woodocrinus was first described, 
a single species only had been found. Indications of others were 
impressed upon the slabs, the surfaces of which were almost com- 
posed of the remains, of the Crinoides. During the last three years 
gi'eat exertions have been made to discover all the fossUs that this 
bed contains — and the gratifyuag result has been, that four or 
five new species have befen added to that which was the type of 
the genus which Professor de Koninck described in a paper read 
before the Royal Society at Brussels, 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 Geology of Yorkshire.' 
The strata below and above it appear to be mifossiliferous. Its 
locality the Carboniferous Rocks on a moor in Swaledale, near 
Richmond, in Yorkshire. 
These Crmoides are associated with the teeth of Petalodus 
Hastingii ; and not the slightest trace of any other fossil has yet 
been fomid with them. They lie in the bed a confused mass of 
stems, caHces 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 fi'om the zone of 
water where they lived; and that the locality in which they are 
found Avas 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 they ofi'er some 
peculiarities which tend to modify and to complete the character 
which has been assigned to the genus.
