INTRODUCTION. 
the Upper Silurian and Old Red Sandstone of Herefordshire, 
bequeathed to the Trustees, 1874. 
Peach Collection .—A series of fossil fishes from the Lower Old 
Red Sandstone, chiefly of Caithness, collected by the late Mr. Charles 
W. Peach, A.L.S., obtained by purchase, 1870. 
Whincopp Collection .—Fossils from the Pliocene Crags of Suffolk 
and Norfolk, collected by the late Mr. W. Whincopp, of Woodbridge, 
purchased through Mr. E. Charlesworth. 
It may be added that a few of the type specimens of Ichthyo- 
dorulites from the Carboniferous Limestone, formerly in the Collec¬ 
tion of the Earl of Enniskillen, were lost in transit immediately 
before the acquisition of this Collection by the Museum. These 
specimens are noted in the Catalogue as “ olim Enniskillen Col¬ 
lection.” 
Supplement. 
On account of the rapid progress x of researches in Fossil Ichthyo¬ 
logy at the present time, it seems advisable to defer the issue of any 
Supplement to this Catalogue until its completion. In regard 
to Part I., we would thus only add that a recent discovery (Proc. 
Zool. Soc. 1889, p. 450) suggests that the so-called Squatina 
crcissiclens is the trunk of iSclerorhynclms atavus ; while an important 
Permian genus and species, Dichelodus acutus (C. Giebel, Zeitschr. 
gesammte Naturw. vol. ix. 1857, p. 121, pi. iv.), is unfortunately 
overlooked, both in this Catalogue and apparently in all the 
synoptical accounts of the Cochliodontidae hitherto published.
