Adult.--Differs from Sarcops calvus only in having the back black

forming a distinct dark area between the silvery gray of the hind

neck in front and of the rump and tail-coverts behind.

Until recently Sarcops has been considered to be a monotypic genus. It

is true that in 1877 Sharpe described Sarcops lowii from Sibutu,

but as the type of this species remains unique we may consider its

status to be at least doubtful. In 1895 Grant called attention to

some differences between specimens of bald starlings collected in

localities east of the meridian 122 and those from localities west

of that line. Quoting in part from Grant: "we find that east of

longitude 122 degrees, or thereabout, all the Philippine examples

of S. calvus have the mantle and upper back brownish black; while

west of this line all have the upper parts uniform silvery gray;

intermediate forms being met with only in localities situated along

the line where the two forms intergrade."

In 1906 Grant designated the eastern race as Sarcops melanonotus which

is here recognized. The difference between the two races, while evident

enough in extreme examples, is not always well marked. As Grant states,

specimens taken near the meridian 122 are usually intermediate in the

color of the mantle and are not satisfactorily referable to either

race. These intermediate birds occur in Basilan, Bohol, Marinduque,

Luzon, Tablas, Bohol, and Cebu. In Luzon and Bohol, at least, both

varieties and intermediate specimens have been found.

Under these conditions it will be understood that the distribution of

the two races of Sarcops, as indicated by islands, is only tentative,

while the assignment of the various collectors to their proper places

is more or less a matter of guesswork.

Genus GOODFELLOWIA Hartert, 1903.

Bill shorter than head; nostrils overhung by antrorse frontal plumes;

bare space around each eye much smaller than in Sarcops; a long crest

of decomposed feathers springing from the crown; tail much longer than

wing; rectrices graduated; plumage black, glossed with steel-green;

a large white patch on rump.
