I have never met with authentic Philippine examples of any Pied Wagtail ; and 

 I am therefore unable to identify Sonnerat's species {cf. Swinhoe, P. Z. S. 1870, 

 p. 120).

Hah. Guimaras, March {Meyer). 



Above, the general ground-colour is olive-grey, each feather broadly centred with 

 brown, most marked on the head and nape. The rump, upper tail-coverts, and shoulder- 

 coverts are almost uniform olive-grey, the brown centres not being very evident. The 

 whole of the wing-feathers are brown edged with albescent. The first primary con- 

 spicuously edged with greyish albescent, as in G. richardi and C. rufida. Between the 

 base of the bill and the eye is a bald patch of albescent feathers, which are continued 

 over the eye rather more narrowly, and then dilate into a broad albescent stripe above 

 the ear-coverts. Lores brown, bordered underneath by an albescent stripe, which extends 

 below the eye and loses itself in the cheek. Ear-coverts dark brown. Under surface 

 of body albescent. Throat almost pure white. A few of the breast-feathers with 

 narrow dark brown centres. Middle pair of rectrices brown, with albescent fringes ; 

 outer pair almost pure white ; penultimate pair white, with half of the inner web 

 brown ; remaining pairs brown. A narrow brown line foUows the rami of the mandible. 

 Legs yellow ; maxilla brown ; mandible yellowish. Neither example exhibits a trace 

 of rufous or ferruginous. The bill is thicker than in C. rvfula (ex Malacca), of which 

 species this Guimaras bird is a representative. 



Wing 3 inches; tail 2-50 ; bill, from nostril 0'37; tarsus 1-12; hind claw 0'50. 



This Pipit is closely allied to Corydalla hasselUi, Temm.', ex Borneo, of Gray's Hand- 

 list, no. 3655 ; but, judging from the single example so entitled in the British Museum, 

 the Bornean species differs sufficiently to make a comparison with a greater number of 

 individuals desirable. 



Corydalla infuscata, Blyth (J. A. S. B. 1861, p. 96, "Philippines"), was described 

 from a Foochow-hills specimen, a small and dark-plumaged race of C. richardi, sent by 

 Mr. Swinhoe to Mr. Blyth {cf. Swinhoe, P. Z. S. 1863, p. 272, no. 75). 



' Apparently a Museum title. No description of the species has hitherto appeared.
