are dark ash-colour. This last species I obtained in the inte- 

 rior of Martaban, near the Shan frontier. T. rupicola must be 

 the species (no. 155) described by Dr. Adams (P. Z. S. 1859, 

 p. 187) as " common in certain localities on the Cashmere ranges 

 and Ladakh ; plentiful likewise to the east towards Simla. Fre- 

 quents grassy mountain-sides or valleys in the lesser ranges." 

 It is certainly common near Simla ; and it is the T. orientalis of 

 Capt. T. Hutton, who states that it is " a mere summer visitant 

 at Mussooree, where it arrives early in April, when every wood 

 resounds with its deep-toned cooing. It is not found lower than 

 6000 feet with us, and departs in October" (J. A. S. B. xvii. 

 pt. 2. p. 13). But what is Dr. Adams's T. orientalis (Lath.), 

 no. 153, which occurs "in fields and cultivated districts in 

 Cashmere and Ladakh " ? 



794. TURTUR CAMBAYENSIS. 



This Dove, in India, assuredly does not evince the partiality 

 for date-palms manifested by the barely separable T. cegyptiacus 

 in North Africa, as observed by Mr. Tristram (Ibis, 1860, 

 p. 69). 



795. TURTUR SURATENSIS. 



Dr. Jerdon erroneously identifies T. chinensis {Columha chi- 

 nensis, Scopoli; C. risoria, var. l3, Latham), founded on the 

 " Tourterelle de la Chine " of Sonnerat, by whom it is correctly 

 figured, with T. tigrinus (Temra.) of the Indo-Chinese and Ma- 

 layan countries. The former is distinguished by its consider- 

 ably larger size (having the wing and tail respectively 6 inches 

 long), by the deep ash-colour, instead of white, of its lower 

 tail-coverts, and especially by having the back and wings plain 

 unspotted dark brown, with merely a slight tinge of grey at the 

 bend of the wing, the spotting of the nape being precisely 

 similar. T. tigrinus differs from T. suratensis only in wanting 

 the two conspicuous pale spots at the extremity of each feather 

 of the mantle ; and I have seen no intermediate specimens. T. 

 chinensis has a distinguishable note ; but I remarked no differ- 

 ence of voice in the Indian and Burmese races. I have had 

 the T. chinensis in captivity, sent me by Mr. Swinhoe*.
