Dendrobiastes hyperythra jugosae, subsp. nov. 



Type, adult male, U. S. National Museum, No. 251,100, Goenoeng Lehio, 

 Celebes, January 17, 1917. Collected by H. C. Raven (original No. 

 3412). 



Similar to Dendrobiastes hyperythra vulcani Robinson' from Java but 

 averaging lighter above; the belly with more white; wing longer. Wing, 

 62; tail, 43; culmen, 10 mm. 



The female is more different than the male. The back is more brownish 

 olive; the superciliary and lower parts more of a clay color, not hght buff; 

 edgings of the remiges darker than in the Javan form. 



Remarks. — The above race is founded upon a good series from the 

 mountains of north and north central Celebes. For comparison I have had 

 a small series of topotypes of D. h. vulcani, two male paratypes of D. h. 

 annamensis, and one male from Kina Balu, north Borneo. While the males 

 of the Celebes and Java forms are quite similar, the females are quite 

 different. The female of the Javan form has the pectoral band very pro- 

 nounced with the throat much lighter, while in that from Celebes the throat 

 is little lighter than the chest. The two males of D. h. annamensis are 

 quite similar to same sex from Celebes but they appear to be larger and the 

 brown edging on the remiges more pronounced. The single male from 

 Kina Balu is lighter above and much lighter below than any specimen 

 before me and probably represents a distinct form. 



Myzomela chloroptera juga, subsp. nov. 



Type, adult male, U. S. National Museum, No. 256,965, Indrulaman, 

 south Celebes, October, 1895. Collected by Alfred Everett. 



Similar to Myzomela chloroptera chloroptera but much grayer on the 

 breast and belly; the back, wings and tail distinctly brownish; the red duller; 

 size slightly smaller. Wing, 57; tail, 37; culmen, 15.5 mm. 



Remarks. — In a large series fron north Celebes, the type locality of 

 Myzomela chloroptera Walden, the breast and belly is rather strongly 

 washed with sulphur yellow and the scapulars, wings, and tail are dis- 

 tinctly black. In a series of four males from South Celebes (three from 

 the type locality and one from Bonthain Peak) the breast and belly almost 

 lack the sulphur wash, making them more grayish; the scapulars, wings, 

 and tail are distinctly brownish; and the reds are duller. The slight differ- 

 ence in size between the two series might disappear upon the measurement 

 of a larger series but the color differences are very great upon comparison. 

 Meyer and Wiglesworth" had noticed these differences but their series was 

 very small. 



A male from Saleyer Island has the red of the plumage much lighter than 

 Myzomela chloroptera juga; otherwise it does not differ materially, but 

 whether this difference is due to age or not it is impossible to say until a 

 larger series has been examined.
