ART. 22. BIRDS FROM THE KARIMATA ISLANDS OBERHOLSER. 6 



MUSCITREA GRISOLA SECEDENS (Stresemann). 



Pachycephala grisola secedens Stkesemann, Novit. Zool., vol. 20, No. 2, 

 June 17, 1913, p. 355 ( " S'irhassen " [Island, Natuna Islands]). 



A single adult female, No. 180581, U.S.N.M., from Pulo Senitu, 

 taken, August 16, 1904, Length in jflesh, 157 mm. It is apparently 

 identical with birds from the Natuna Islands. It is in the midst of 

 the molt of both quills and contour feathers. 



CYORNIS BANYUMAS KARIMATENSIS, new subspecies. 



SudspecifiG characters. — Similar to Cyomis hanyumas rufigastris 

 (Raffles) from Sumatra, but much larger; throat, breast, and crissum 

 decidedly darker. 



Description. — Type, adult male. No. 181667, U. S. N. M. ; Karimata 

 Island, off southwestern Borneo, October 4, 1908 ; Dr. W. L. Abbott. 

 A narrow line across the extreme anterior part of forehead at base of 

 maxilla, together with lores and chin, black; rest of forehead and 

 supra-loral stripe jay blue, passing into gendarme blue on supra- au- 

 ricular region ; tail brownish black, but the two middle rectrices and 

 outer webs of all the rest of the same color as the posterior upper 

 parts ; wings fuscous black, but the outer webs of tertials, the narrow 

 margins of secondaries and of the basal two-thirds of primaries, to- 

 gether with the exposed areas of greater and median coverts, like 

 the posterior upper surface; lesser wing-coverts jay blue; sides of 

 head, of throat, and of neck like the cervix; jugulum and sides of 

 breast between cinnamon rufous and xanthine orange; throat the 

 same but rather lighter; middle of breast, together with sides and 

 flanks, deep ochraceous buff ; middle of abdomen very pale ochraceous 

 buff ; crissum ochraceous tawny ; axillars and inner under wing-cov- 

 erts colored like the flanks and sides ; outer under wing-coverts light 

 ochraceous buff", mixed with fuscous; edge of wing jay blue. 



Measurements. — Adult male (type) ; total length in flesh,^ 166 mm; 

 wing, 78; tail, 67; exposed culmen, 12; height of bill at base, 4.5; 

 tarsus, 18 ; middle toe without claw, 13. 



Wliile we have but a single example, this is an adult male in 

 perfect plumage, which differs so much from all the known forms 

 of the genus that we have no hesitancy in describing it as new. 

 Although we have not seen the female, this new bird is evidently 

 a subspecies of Cyomis hanyumas. It differs from all the described 

 forms of Cyomis from Borneo in its great size and very deeply 

 colored crissum, which is nearly as dark as the jugulum. It is 

 apparently confined to the Karimata Islands.
