252 APPENDIX. 



the tarsi are very short, but the toes large and 

 strong. The form of the bill, 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 Laniadce ; the 

 bill, in fact, is shrike-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, &; front, ^ ; wings, 3; tail beyond, ]| ; 

 base, 2| ; tarsus, T 6 . General size and structure 

 of the last, except in the bill, which, although small, 

 has the short and dilated form, typical of My'iagra, 

 to which it obviously leads, although it retains the 

 short and stout feet of M. ruficauda. This species 

 closely resembles the Mies, melanops of Nepaul in 

 its size, and much in its colour ; but it has not the 

 same changeable tints : the lores are not velvet- 

 black, and the wings only measure 3, instead of 

 3 T 5 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.
