on the fish fauna of the pendleside limestones, 
by edgar d. wellburn, l.r.c.p.e., f.r.i.p.h., f.g.s., etc. 
Introduction. 
Since the appearance of the valuable and interesting memoirs 
of Dr. Wheelton Hind, F.G.S., a great interest in these limestones 
has been aroused in Yorkshire and elsewhere, and the author having 
worked in and collected a good number of fish remains from these 
rocks, considers that the Fish Fauna of the beds may prove of in- 
terest, especially as some of the fish are new to science, whilst the 
fauna as a whole is of importance as bearing on the question of the 
stratigraphical position of the rocks. 
As a whole the fauna is very similar to that of the Millstone 
Grits* above, whereas it is very dissimilar to that of the Yoredales 
(Phillips) of North-west Yorkshire, but this is only mentioned here, 
as it is the intention of the writer to discuss this question at length 
later, when he hopes to adduce facts strongly supporting Dr. Hind's 
theory of the age and position of these limestones.
