477. HYPSIPETES CAMIGUINENSIS McGregor.

CAMIGUIN RED-EARED BULBUL.

• Hypsipetes camiguinensis McGregor, Phil. Jour. Sci. (1907), 2, sec. A, 347.

Camiguin N. (Worcester, McGregor).

Diagnosis.—Similar to H. fugensis and to H. batanensis but larger; bill and tail longer; flanks less rufescent. Male, type: Length in flesh, 295; wing, 136; tail, 124; culmen from base, 33; bill from anterior margin of nostril, 21; tarsus, 25.

The specimens of Hypsipetes obtained in Camiguin Island are in such poor condition that it is impossible to give color characters, but I believe adults in good plumage will be found to differ considerably from both H. fugensis and H. batanensis.

Genus IOLE Blyth, 1844.

This genus differs from Hypsipetes in having longer rictal bristles, the longest being decidedly more than one-half as long as the tarsus, and in having the nuchal hairs more strongly developed. The three yellow plumaged species, Iole striaticeps, everetti, and haynaldi, approach Criniger (=Trichophorus) both in color and in the development of nuchal hairs, but in the latter genus the bill is relatively shorter and the culmen is more curved.

  • b¹. Above olive-brown with whitish shaft-streaks; below ashy white with a strong tinge of yellow. striaticeps (p. [505])
