a, b. Olga Baj', September 1879. 



c. Gensan, loth August, 1880. 



The first two look like young birds, the underparts being much 

 spotted and both being of small size. Specimen c is a large speci- 

 men with a very big bill, perfectly adult ; the middle region of the 

 underparts is nearly covered with the black feathers of the summer 

 garb. 



14. Charadrius fulvus, J. F. Gm. 



Ckaradrius fulvus, David et Oust. Ois. Chine, p. 424 (1877); 

 Salvad. Orn. Pap. e Mol. iii. p. 294 (1882). 



a, b. Olga Bay, September 1879. 



Both young birds, fulvous on flanks and underparts. Their dimen- 

 sions are : — Bill (culmen) 0*020 m., wing 0*164 m., tarsus 0*040 m. 



15. Charadrius dominicus, Miill. 



Charadrius dominicus, Miill. S. N. Suppl. p. 116 (1776). 



Charadrius virginicus, Harting, P. Z. S. 1871, p. 1 15 ; Dress. B. 

 of Eur. vii. p. 447 (1871). 



a. Olga Bay, September 1879. 



We were rather surprised to recognize a specimen of this species 

 amongst the Plovers collected on the Manchurian coast ; still it must 

 be remembered that C. dominicus and C. fulvus have both been 

 found in Heligoland (cf Blasius, Ibis, 1862, p. 71), and that both 

 species occur at Alaska (cf. Stejneger, Bull. U.S. Nat. Mus. no. 29, 

 p. 105). It is evidently a young bird, with the underparts greyish, 

 more or less spotted with white. Its dimensions are : — Bill (culmen) 

 0-022 m. ; wing 7*- inches = 0-180 m. ; tarius 0*040 m. It agrees 

 with all the characters of the North-American Golden Plover, and 

 differs from specimens of G. fulvus in being larger, less golden above, 

 and more greyish on the nape. 



16. jEgialitis mongolica (Pall.). 



JEgialiiis mongolicus, David et Oust. Ois. Chine, p. 427 (Corea). 



J^gialitis mongolica, Salvad. Orn. Pap, e Mol. iii. p. 299 (1882). 



a, b, c, d. Olga Bay, September 1879. 



The first specimen is an adult in perfect plumage, the three fol- 

 lowing are immature birds, similar, and agreeing also in being 

 smaller than the first. 



17. Strepsilas interpres (Linn.). 



Strepsilas interpres, David et Oust. Ois. Chine, p. 433 (1877); 

 Salvad. Orn. Pap. e Mol. iii. p. 289 (1882). 



a, b. Olga Bay, September 1879. 



Two young birds in their first plumage, the feathers of the upper 

 parts being margined with ochraceous.
