APPENDIX. 
the tarsi are very short, but the toes large and 
strong. The form of the hill, its stoutness, and 
compressed sides, accords with that of the Mus. ru- 
becola ; and both offer a miniature resemblance to 
the genus Tephrodomis among the Laniadm ; the 
bill, in fact, is slirike-like ; the first joint of the 
outer toe is free, and the inner one is slightly 
shorter. 
2. Muscicapa thalassina. 
Entirely greenish-blue ; beneath paler ; lores grey ; fourth 
quill the longest ; tail even \ wings three inches long. 
Inhabits India. Total length, 6 inches; bill, 
gape, fs i front, {si '"’ings, 3; tail beyond, It; 
base, 2| ; tarsus, T 8 5 . General size and structure 
of the last, except in the bill, which, although small, 
has the short and dilated form, typical of Myiagra , 
to which it obviously leads, although it retains the 
short and stout feet of M. rujicauda. This species 
closely resembles the Mus. mdanops of Nepaul in 
its size, and much in its colour ; hut it has not the 
same changeable tints : the lores are not velvet- 
black, and the wings only measure 3, instead of 
3 ^ 5 . This difference of colour, slight as it may 
appear, is very observable when the two species are 
compared ; the fourth quill is the longest.
