P. 3633 b. Head, pectoral fin, and anterior squamation of a large 
fish, exhibited from the left side and shown of the natural 
size in PI. IV. fig. 1. Many of the bones are well 
displayed, and are indicated in the figure by the lettering. 
There are very few traces of a tubercular ornament, 
apparently confined to the supratemporal, post-temporal, 
and operculum, though a few isolated tubercles also occur 
on the cranial roof. The postclavicular scales are con¬ 
spicuous, and some of the anterior flank-scales are deeper 
than broad. fy' Enniskillen Coll.

mains of surrounding bones and scales ; the undescribed

P. 870. Left mandibular ramus, inner aspect, probably of this 
species. As shown by the accompanying illustration 
(fig. 34), the angular (ag.), articular (art.), coronoid 
(cor.), dentary (d.), and splenial elements (spl.) can be 
distinguished. Egerton Coll.
