 Siri, Java Sea, December 11, 1907; Dr. W. L. Abbott. Upper parts 

 dark brown, between dresden brown and mummy brown, somewhat 

 darker on the pileum, and inclining to cinnamon brown on the rump, 

 the feathers of the forehead with broad buffy central areas, those of 

 the fore part of crown with narrow shaft lines of the same color; 

 upper tail-coverts reddish brown, between argus brown ai.d Sanford's

 terminally shading toward Prout's brown; primaries and secondaries 

 dusky sepia, the outer webs of secondaries, with all of the tertiais and 

 superior wing-coverts, Prout's brown, and the outer webs of the 

 primaries between cinnamon brown and dresden brown; sides of 

 head brown like the back, but the lores mixed with pale grayish from 

 the basal portion of the feathers, the superciliary region also slightly 

 grayish and with narrow shaft lines of grayish or buffy white; auricu-

This new subspecies is more nifescent on the upper parts and on sides 

 of neck than Malacocinda aohotti huttihoferi from Borneo; also more 

 extensively and brightly tinged with ochraceous and ochraceous 

 buff below. It thus really more closely resembles Malacocinda 

 ahhotti olivacea from the Malay Peninsula. The Bornean bird, 

 Malacocinda ahhotti hiittikoferi,^ while it seems to be but subspecifi- 

 cally different from the Malay Peninsida race, Malacocinda ahhotti 

 olivacea, is yet a recognizable form, differing in less rufescent upper 

 surface, and less extensively and brightly ochraceous under parts. 

 The type of Malacocinda ahhotti sirensis is the only specimen ob- 

 tained by Doctor Abbott. 



The present species, Malacocinda ahhotti Blyth, is clearly so differ- 

 ent structurally from Turdinus macrodactylus, the type of the genus 

 Turdinus, that its generic separation is apparently necessary. The
