Penelopides affinis, Tweeddale, Ann. & Mag. Nat. Hist. ser. 4, vol. xx. p. 534 (1877) ; id. Proc. Zool. Soc. (1877) 

 p. 824. sp. 29, (1878) pp. 108, 341, 947. 



Hab. Zamboanga, Butuan, Surigao, Island of Mindinao, Dinagat, Amparo, South Leyte, Philippines 



(Everett) . 



This bird, described by the late Lord Tweeddale {I c), is a representative form of 

 P. panini, and differs in not having the perpendicular grooves on the lateral plates of the 

 maxilla, these being smooth, and also by having the grooves on the mandible straight instead of 

 curved as in P. panini. The bill is altogether less powerful. The abdominal region and under 

 tail-coverts are coloured like the breast, and not rufous as in its ally ; and the rectrices have 

 a black band at their insertion. Lord Tweeddale states that." in one example some of the black 

 upper tail-coverts are tipped and margined with dirty rusty. An old Surigao female has 

 several of the secondary quills margined with ferruginous. A young Surigao male has a small 

 part of the outer webs of the fourth, fifth, and sixth primaries edged albescent. An old Surigao 

 male has the thigh-coverts, ventral region, and under tail-coverts pale rufous, and most of the 

 upper tail-coverts as in P. pcrnini, otherwise as in typical affinis. In a Butuan and a Surigao 

 male, the middle pair of rectrices, with the exception of the basal black band, are rufous 

 throughout, the normal black terminal band being only indicated by black blotches. The new 

 rectrices are pale fulvous white (instead of ferruginous) when they first come in. The number of 

 grooves on the mandible varies from three to four. The extreme altitude of the bill, ending at 

 the nostril, is 1*06 inch, whereas in P. pcmini it is 137.

The specimens figured are the types of Lord Tweeddale's species, kindly loaned to me by 

 Captain Bamsay, their present owner.
