"This species is closely allied to Siphia philippinensis, but is much 

 larger, of a more greenish blue, and is especially distinguished by the

 nous-brown on the upper tail-coverts; rectrices dark sepia-brown, the

 are wholly ferruginous-brown, and all showing in certain lights close 

 obsolete transverse bars ; under surface of the quills hair-bro^vn ; primaries 

 dark brown, and all except the first and second margined basal ly on the 

 outer webs by a thin line of ferruginous-brown; the secondaries and 

 tertials also dark brown, but increasingly margined [with] bright ferrugi-

"In another female from Balabac the dimensions are rather less, but 

 in my original Puerto Princesa specimen they agree very closely. This 

 species is marked by its large bill. The culmen in the type-skin of the 

 male, measured from its insertion in the skull, is 17 mm., and it is the 

 same in a female collected by Mr. AVliitehead at Taguso in Palawan." 

 {Everett.) 



"Abundant in Palawan and the Calamianes islands. Habits like 

 those of S. philippinensis. Five males average : Length, 149 ; wing, 75 ; 

 tail, 64; culmen, 18; tarsus, 17; middle toe with claw, 18. Three
