Part 130

"Young male (with undeveloped casque) differs from the adult in having the upper tail-coverts chestnut and the black band across the end of the tail suffused with rufous.

"Adult female.--Head, neck, and under parts dull black; back, rump, upper tail-coverts, and wings black, glossed with dark green; tail resembles that of the male. 'Naked skin round eye and on chin and throat dark blue: iris crimson, feet dark greenish leaden.' (Everett.) Bill and casque brown, base of lower mandible with indistinct obliquely transverse grooves. Length, 500; wing, 218; tail, 175; tarsus, 41.

BASILAN TARICTIC.

Penelopides basilanica Steere, List Birds & Mams. Steere Exped. (1890), 13; Grant, Cat. Birds Brit. Mus. (1892), 17, 375; Sharpe, Hand-List (1900), 2, 65; McGregor and Worcester, Hand-List (1906), 56.

Basilan (Everett, Steere Exp., Bourns & Worcester, McGregor).

"Much like P. affinis of Mindanao, but differs from it in having the rufous upon the tail reaching to and beneath the upper tail-coverts, so that the whole base of the tail appears rufous, though some specimens show some black at the bases of the feathers when they are uncovered. The sides of the mandible are also flesh-colored to their bases instead of being black behind as in P. affinis." (Steere.)

"The differences enumerated by Steere between this species and P. affinis, though slight, occur in all the specimens secured by us. A male measured, 610 in length; wing, 231; tail, 205; tarsus, 45; middle toe with claw, 46. A female, length, 559; wing, 211; tail, 183; tarsus, 39; middle toe with claw, 45. Eyes red to umber-brown; legs and feet greenish slate-color; nails black; bill white at tip, black on crest, remainder mottled with reddish brown." (Bourns and Worcester MS.)

300. PENELOPIDES SAMARENSIS Steere.

SAMAR TARICTIC.

Bohol (McGregor); Leyte (Everett, Steere Exp.); Samar (Steere Exp., Bourns & Worcester, Whitehead).

Male.--Very similar to the male of P. affinis but upper tail-coverts very pale buff. Wing, 260; tail, 230; bill from nostril, 90.

Female.--Like the female of P. affinis. Wing, 235; tail, 225; bill from nostril, 72.

"A well-marked species. Five males average, 606 in length; wing, 232; tail, 208; tarsus, 42; middle toe with claw, 52. Eyes reddish brown; legs and feet slaty black; nails brown to black; bill dark brown, reddish at the tip and around grooves.

"It seems probable that Everett's Dinagat birds were of this species, but they can, of course, be placed here only provisionally." (Bourns and Worcester MS.)

Genus CRANIORRHINUS Cabanis and Heine, 1860.

Jaw, entire chin, and a large space around eye naked and bright red; base of lower mandible deeply and obliquely chiseled, upper mandible smooth; casque high, greatly compressed, its outline gently rounded behind and abruptly truncated in front; in the female the casque is smooth and has a sharp ridge above, in the male it is somewhat rounded above, and the sides are distorted by deep vertical plications.
