438 Mr. R. Swiuhoe's Ornitholoyical Notts mada at Cliefoo. 



these last was sent from Lake Baikal. It is odd that these 

 two allied species should meet to winter in the Moluceas. 

 I extract from my notes on the fresh bird : — ''The fat that 

 abounds on the rump of birds in migration had in these 

 nearly disappeared. The testes of the males were whitish 

 and much swollen. The female was somewhat smaller than 

 the males, was less smoked on the underparts, and had a 

 lighter bill. 



'' ^ . Rim round eye yellowish. Bill on upper mandible 

 blackish brown, with yellowish edge ; inside of mouth, rictus, 

 and basal half of lower mandible chrome-yellow, the last 

 brownish towards tip. Legs, toes, and nails light flesh-brown, 

 darker on the toes. 



" Length 7\ inches. Wing 3*25, '85 longer than tertiaries, 

 1'96 short of tail; first quill diminutive, second '1 shorter 

 than the third and longest. Tail 3 inches, of twelve much 

 graduated pointed feathers, outer one shorter than centrals. 

 Under tail-coverts 1-08 short of tail-tip. Tarse 1*1 ; middle 

 toe and claw 1*06 ; hind toe and claw '68. Bill in front '65, 

 from gape "95." 



22. Mock Nightingale. Arundinax canturiens, Swinh. 

 Mr. Campbell brought me a specimen of this on the 15th 



October. It was the only one I saw at Chefoo. On the 29th 

 October I got a male at Shanghai. I would call it a vagrant 

 rather than a migrant species. I will resort to Blyth's generic 

 name for this group, as I find his type, A. olivaceus { = Turdus 

 aedon, Pall.) [cf. P. Z. S. 1871, p. 353) is as much a bush- 

 lover as any of ours, and not a reed-skulker. His genus has 

 priority, though the name is any thing but apt. 



23. David^s Small Mock Nightingale. Arundinax da- 

 vidianus, J. Verr. 



In my " Revised Catalogue " (P. Z. S. 1871), under Her- 

 bivocula flemingi, I allude to this species as one of two sizes in 

 the Paris Museum from Pekin. Mons. J. VciTeaux described 

 it under tlie above name with Pere David^s novelties from 

 INIoupin (Chinese Thibet, to the north-west), (Nouv. Arch, du 

 Museum, t. vi. (1870), p. 37. no. 18). I cannot understand
