AM Pr iebied to Professor Orville A. Derby for the opportunity of 
_ studying some fish-remains from the Cretaceous of North-East 
Brazil, which were examined by the late Professor Cope and partially 
described by him, without illustrations, in 1886. I had the privilege 
of seeing some of these fossils at Philadelphia in 1890, and made 
a few notes which were incorporated in the British Museum Catalogue 
of Fossil Fishes. I have now undertaken a renewed and more detailed 
study of the collection, which suggests the desirability of publishing 
the following supplementary observations. 
ENCHODUS SUBHQUILATERALIS, Cope. (Pl. VII, Figs. 1, 2.) 
1886. Enchodus subequilateralis, K. D. Cope: Proc. Amer. Phil. Soc., vol. xxiii, 
p. 3. 
This species is represented only by palatine bones (‘premaxillaries’ 
of Cope) and by a tooth probably of the dentary bone, from Maria 
Farinha, Province of Pernambuco. The type-specimen (PI. VII, Fig. 1) 
exhibits the palatine tooth, already described by Cope. A second 
specimen (Fig. 2), exposed from the inner aspect, shows that the 
palatine bone is short and stout, with the ethmoid articulation 
extending to its anterior end, where the tooth is fixed and directed 
downwards. 
PaLHOBALISTUM FLABELLATUM, Cope, sp. (PI. VII, Fig. 3.) 
1886. Pycnodus flabellatus, K. D. Cope : Proc. Amer. Phil. Soc., vol. xxiii, p. 6. 
1895. Paleobalistum flabellatum, A. 8. Woodward: Cat. Foss. Fishes Brit. Mus., 
pt. ii, p. 275. ’ 
The only known example of this interesting Pycnodont is exposed 
from the right side and shown of one-half natural size in Pl. VII; Fig. 3. 
lt lacks the greater part of the head, besides the front half of the 
dorsal and ventral borders, but is sufficiently well preserved to leave 
no doubt as to its generic determination. Immediately behind the 
rather large orbit (ord.) a cluster of slender ossified gill-supports is 
seen, and below this is part of the widely expanded left preoperculum 
(pop.) exposed from its imner face. In the axial skeleton of the
