bird from a bed low down in the Cathedral cave, which is figured in the accompanying

Ketupa ceylonensis (Gmelin). 
Limb-bones. — This species is represented by a right femur 1 (No. F. 313a) and 
the distal half of the right tibio-tarsus 
from bed Ca in the Cathedral, as well as 
by the distal portion of the right tarso- 
metatarsus from bed Cb, and the third 
phalangeal of the third digit of the pes 
from bed Ca in the same cave ; the three 
last-named bones being figured from the 
anterior aspect in the accompanying wood- 
cut (fig. 6 a, b, d). These specimens agree 
exactly with the corresponding bones of 
the existing bird. As characteristic features 
in the tibio-tarsus of Ketupa and allied 
genera may be mentioned the absence at 
the distal extremity of the anterior surface 
of a bridge of bone over the extensor tendons, and the presence of a tubercle on 
the inner border for muscular attachment. 
Bubo coromandus (Latham). 
Syn. TJrrua coromanda, Auct. 
Phalangeal. — The second phalangeal of the third digit of the pes of a very 
large owl from bed Cc in the Cathedral represented in woodcut fig. 6c, agrees, as 
far as can be determined from comparison with a dried specimen, with the corres- 
ponding bone of Bubo coromandus , which now inhabits the Carnatic, lower Bengal, 
and the outer Himalaya. 
Francolinus pictus (Jardine and Selby). 
Tarso-metatarsys. — Evidence of the existence of the painted francolin, which 
replaces the black francolin (F. vulgaris ) in central and parts of southern India, is

the right tibio-tarsus (A), of the right tarso -metatarsus 
(B), and the 3rd phalangeal of the 3rd digit of the pes

digit of the pes. All the specimens are from the 
Cathedral cave. 
l The collection also contains a perfect right tibia (No. F. 311) marked as from bed Cain the Cathedral, which, however, 
appears to be recent.
