160 Mr. Blyth's Commentary 



9. A. charltoni (Eyton, Ann.& Mag. N. H. 1845, xvi. p. 230). 

 Malayan Peninsula^ in Pinang, and Province Wellesley. (Type 

 of Tropicoperdix, nobis, passim) . Tenasserim Mountains. 



10. A. chloropus, Tickell (J. A. S. B. xxviii. pp. 415, 453). 

 Tenasserim Mountains. 



(C. With a large bare space in front of neck.) 



11. A. punctulata (Hardw. 111. Ind. ZooL). Hab. ? 



12. A. crudigularis {Oreuperdix crudigularis, Swinhoe, Ibis,

The Perdix oculea, Temm. (Pig. et Gall. iii. p. 408; Tetrao 

 ocellatus, Raffles, Tr. Linn. Soc. xiii. p. 322 ; Hardw. Ill, Ind. 

 Zool.), of Mergui province and Sumatra, is the type of my Ca- 

 loperdix ; and P. thoracica, Temm. (Pig. et Gall. iii. p. 335, 

 Perdix and Arhoricola sphenura, Gray), is the type of Bambusi- 

 cola, Gould, to which a second species has been added by Mr. 

 Swinhoe from Formosa, B. sonorivox, Gould (B. As. pt. xvi.). 



826. Perdicula cambaiensis (Latham) ; Temm. PI. Col. 

 447. 



The peculiar quivering whistle, which this species almost con- 

 stantly utters continuously, should be noticed. It is the only 

 species in Bengal. In a letter received from Capt. Beavan he 

 states that this species is tolerably common in Maunbhoom. " I 

 have got," he adds, '' a female (by dissection) exactly like the 

 male, with black bars across the breast, and a male without any 

 bars at all (simply pale rufous with white shafts to the breast- 

 feathers); and a young female (half-grown) is the same." I 

 have asked Capt. Beavan to procure a good series ; for the varia- 

 tion of plumage is certainly not yet sufficiently understood. 

 Perdix raalteni, Temm., of Flores and Timor, appears to me to 

 be a Perdicula] but I should like to see more examples of it. 

 If the male wants the blunt tubercle in place of the spur, so also 

 does that of Francolinus pictus as compared with F. vulgaris. 



828. Perdicula erythrorhyncha (Sykes) ; Microperdix 

 ei-ythrorhyncha, Gould, B. As. pt. xiv. pi. 



This certainly is not a Perdicula, but appears to me more 

 nearly allied to Excalfactoria. In other words, it is a Quail, and 

 not a diminutive Partridge as the name Microperdix implies. 



* There would also seem to be a species in the Philippines (Martens, 

 J. f. O. 1866, p. 25).
