20 PEOCEEDINGS OF THE NATIONAL MUSEUM vol. 77 



This series compared with Muscitrea grisola grisola of the main- 

 land averages browner on the head and has a larger, heavier bill; 

 below, the gray of the chest comes down further and the white of the 

 belly is more restricted. The only two specimens examined from 

 Java are yqvj pale, paler than either M. g. grisola or M. g. secedens 

 and evidently represent another form. One of the males from 

 Pandjang is very much worn, the other five males measure: Wing, 

 82-87.5 (85); tail, 60.5-G7.5 (63.8); culmen, 15-16 (15.5). Five 

 males of M. g. grisola measure: Wing, 82-87 (83.9); tail, 58-61 

 (59.3); culmen, 13-15 (13.9).

Two males and two females, Pulo Eraban, June 12. 



These are considerably^ lighter above and below than the only 

 specimen available from Borneo, an unsexed female without definite 

 locality, for comparison. I am of the opinion that only one of the 

 specimens from Eraban is fully adult. It is a male and measures: 

 Wing, 76 ; culmen, 14.5.

Over 90 specimens were collected, consisting of adults of both sexes 

 and immatures, from the following islands : Raboe Raboe, May 4, 6, 

 and July 27; Derawan, April 25-28 and July 22-25; Samama, April 

 21, 22; Maratua, May 11-20; and Bakungan, May 17, 18. No con- 

 stant differences in color can be detected between series from the 

 main island of Borneo and the small islands off the coast, but the 

 island series average larger, especially the culmen. Thirty males 

 from the small islands giA^en above measure: Wing, 59-65 (62.3) 

 culmen, 18.5-21 (19.5). Six males from northeast Borneo measure: 

 Wing, 58-62.5 (60.5); cuhnen, 17.5-19 (18.2). Males from the 

 Malay Peninsula agree with those from the main island of Borneo in 

 size, as the following will show: Seven males, wing, 60-61.5 (61); 

 culmen, 17-19.5 (18). The males from northeast Borneo and the 

 islands off the coast run remarkably true to type. The lower back, 

 rump, and upper tail coverts are a shining coppery green with little
