104 Richmond — New Birds from the West Coast of Sumatra. 

 Thriponax javensis biittikoferi subsp. nov. 



Type, No. 179,685, U. S. Nat. Mus., adult male, Siaba Bay, Nias Island, 

 March 18, 1903; W. L. Abbott and C. B. Kloss. 



Similar to T. j. javensis (Horsfield), but with the thighs and flanks 

 uniform burl', without blackish bars or spots. Length (in flesh), 462; 

 wing, 228; tail, 167; tarsus, 38.5; culmen, 57 mm. 



Three adults only were collected, but Dr. Abbott notes it as " common " 

 on Nias, and Dr. Biittikofer has already recorded* presumably the same 

 form from the island under the name T. javensis. 



Dicaeum sumatranum batuense subsp. nov. 



Type, No. 180,073, I T . S. Nat. Mus., adult male, Pulo Pinie, Batu Is- 

 lands, west coast of Sumatra, March 3, 1903 ; W. L. Abbott and C. B. 

 Kloss. 



Near Dicseum s. sumatranum Cabanis, but bill smaller; center of chin, 

 throat and chest burly white, as in D. cruentatum (but the light area not 

 so broad); sides of head, neck and body slightly darker than in D. s. 

 sumatranum. Length (in flesh), DO; wing, 48; tail, 25; tarsus, 11; cul- 

 men, 12 mm. The female is similar to D. cruentatum, but the white 

 median line on the underparts is narrower. Both D. s. sumatranum and 

 the new form differ from D. cruentatum in having the red of the upper- 

 parts lighter, with the sides of the neck, body and flanks smoky gray 

 instead of blackish; the scapulars have a greenish (instead of bluish) 

 gloss, and the forehead is black. 



Alcedo meninting proximo subsp. nov. 



Type, No. 17!), 777, U. S. Nat. Mus., adult male, North Pagi Island, 

 west coast of Sumatra. January 4, 1903; Dr. W. L. Abbott. 



Differs from Alcedo m. meninting Horsfield, in having a greenish tinge 

 to the feathers of the crown (present in some specimens of the latter, 

 however), and a generally lighter and more greenish shade to the blue 

 colors of the upper surface (scapulars, wing-coverts, outer webs of sec- 

 ondaries, etc. ). The spots on the wing-coverts are more pronounced, and 

 lighter in color. Length (in flesh), 169; wing, 71; tail, 28; tarsus, 9.5; 

 culmen, 47 mm. 



Five specimens were procured, and Dr. Abbott noted the form as 

 "common'' on the Pagis. 



No direct comparison has been made with A. m. rujigastra Walden,t 

 but judging from the descriptions alone it appears to be not the same, 

 and the Pagi Islands are considerably beyond the known range of A. m. 

 rujigastra. 



* Notes Leyden Museum, XVIII, 1896, 170. 



t Alcedo beavani Walden is simply a substitute name for A. rujigastra.
