CLASSIFIED LIST OF ORGANIC REMAINS FROM THE ROCKS OF THE 
EAST RIDING OF YORKSHIRE. 
BY HENRY C. DRAKE, F.G.S., AND THOMAS SHEPPARD, F.G.S. 
{Read 4th March, 1909 ; Manuscript received Uh March, 1909.) 
This list has been compiled in order to aid future workers 
amongst the rocks of the East R-iding by placing in a convenient 
and compact form all the various and scattered records that 
have been published. In addition, a number of species is now 
placed on record for the first time. 
In the case of some of the beds which have been described, 
and from which lists of fossils have been published over and 
over again, the latest complete list in each instance has been re- 
corded. In this way errors of former lists do not now find a 
place (unless the errors are indicated). 
In the same way the question of nomenclature has to a 
large extent been simplified, as the more recent lists are usually 
the more up to date as regards the names. The present compilers 
have not, of course, attempted the almost hopeless task of en- 
deavouring to give to each species recorded the name which, 
for the moment, is considered to be the correct one. Had this 
been done, many names in the following tables v\^ould only 
with difficulty be identified with those in the previously pub- 
lished lists. 
By means of the following lists not only is it easy to ascer- 
tain whether a given species has been previously recorded 
for a given stratum, or in a given area, but a reference to the 
authority and the place of publication is also given. 
By the " East Riding " the Parliamentary division is re- 
ferred to, i.e., the area south of Filey ravine, south-east of York, 
and east of Selby.
