254—14 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
A-Qinities:- — If, as seems very probably the case, the foregoing specimens belong 
to the present genus, they apparently indicate a large species belonging to the same 
group as the existing A. gagora} of the Granges, but they are insufficient for indi- 
cating specific affinities. 
Geoup. C. BAGARIINA. 
Characters. — Anterior and posterior nostrils approximated. 
Genus. BAGARIUS, Bleeker.^ 
Characters. — Upper jaw longer that the lower; teeth in the jaws cardiform, 
unequal in size ; palate edentulous. Head naked above ; median bones of the 
middle part of the cranium covered with a coarse rugose sculpture. 
Distribution. — At the present day the genus is represented only by B. yarrelli, 
of India and Java ; but a second species has been described by Dr. Gunther® from 
the tertiaries of Padang, in Sumatra, under the name of B. gigas, on the evidence of 
part of the humeral arch and the nearly perfect pectoral fin : the points in which it 
differs from B. yarrelli are not very clearly indicated. 
Species. Bagaeius yaeeelli (Sykes^). 
Syn. Pimelodus hagarius^ Buch. Hamilton.® 
Bagrus yarrelli., Sykes.® 
Bagarius hagarius, Gunther.'^ 
{From the Siwaliks.) 
Characters. — Head depressed, with the snout produced, and the upper jaw pro- 
jecting; eyes small. The band of teeth in the upper jaw narrowest in the middle. 
Skull. — The specimen represented of one-half the natural size in plate XXXVI. 
fig. 1 was obtained by the late Col. Colvin from the Siwaliks of Nahan, and was 
first described by Cantor® as the skull of a gigantic batrachian, but its real nature 
was subsequently determined by M’Clelland,® who showed that it belonged to a 
siluroid fish, and probably to Pimelodus (in the sense in which that generic term was 
then employed). It was referred at a later date to Bagarius yarrelli by the present 
writer.^® 
The specimen comprises the anterior portion of the skull as far back as the 
orbit, (the left orbit being restored in outline from a recent skull), and shows the 
ethmoid {eth.), the greater portion of the f rentals (/r.) with the intervening vacuity 
{h\ the turbinals {tu.'), the anterior and posterior nares {na, no), and the articular 
surface for the barbel {e). The premaxilla, with its band of pointed teeth, as
