of the Andaman Islands. 325 



tionally longer than in the other species. The bill at front is 

 •5 in., and at base "75 in. The female is unknown. Col. 

 Tytler tells me that he once mentioned to Mr. Blyth having 

 seen what he thought at the time was a Niltava flitting 

 through his verandah at Port Blair. He is now confident that 

 it was the species under notice, and wishes me to mention the 

 fact, in case Mr. Blyth may have recorded the existence of a 

 Niltava in the Andamans. 



46. Petrocossyphus cyaneus (Linn.). 



The Blue Rock-Thrush is recorded in Mr. Blyth's previous 

 list. 



47. Geocichla innotata, Blyth. Orange-coloured Ground- 

 Thrush. 



This species was described by Mr. Blyth (J. A. S. B. xvi. 

 p. 146) from specimens procured from the Malayan peninsula*. 

 It is closely allied to G. citrina of India, but is rather darker, 

 and wants the white wing-spot of the latter. In Mr. Blyth's 

 list Col. Tytler remarks that " he had only seen one in his 

 garden on Ross Island,^^ but he has procured several since. 



48. TuRDUs RUFULUS, Drapicz ; T. modestus, Eyton, P. Z. S. 

 1839, p. 103 1. Rufous Thrush. 



This species extends throughout Burmah and Malayasia to 

 the Andamans, according to Dr. Jerdon. 



49. Oreocincla inframarginata, Blyth. 



The Andaman Thrush described (J. A. S. B. 1860, p. 106) as 

 follows : — " Uniform dark olive above with conspicuous pale 

 rufescent whitish supercilia, and light rufescent spots tipping 

 the wings-coverts ; beneath pale, inclining to rufo-fulvous on 

 the breast and front of the neck, pure white at centre of belly ; 

 the lower tail-coverts dark olive, largelv tipped with white; each 



* [The form from the Nicobar Islands, considered by Mr. Blyth to be 

 distinct, and named by him G. alhogularis (J. A. S. B. xvi. p. 146), should 

 be carefully compared with Andaman specimens. — Ed.] 



t [The type of Drapiez's species was from Java, and is probably the 

 same as T. javanicus, Horsf. (Linn. Tr. xiii. p. 148). The identity of the 

 Malayan bird described by Mr. Eyton with the former has yet to be 

 shown. — Ed.]
