 THE SMALL OLIVE BULBUL.

S. Tenasserim). 

 Pycnonotus pusillus. Blanf. & Gates, i, p. 293. 



Vernacular names. None recorded. 



Description. The whole upper plumage and wing-coverts olive- 

 brown, tinged with rufescent on the rump and upper tail-coverts ; 

 tail rufescent-brown ; wings brown, the visible portions suffused 

 with olive; lores and sides of the head ashy-brown; chin and 

 throat ashy-white ; breast and sides of the body ashy-brown 

 washed with fulvous ; abdomen, vent and under tail-coverts dusky 

 yellow ; under Aving-coverts and axillaries pale ochraceous yellow. 



Colours of soft parts. Iris crimson, an ophthalmic ring vivid 

 orange-yellow but this withers away in skins and is not discernible ; 

 bill black, gape and base of lower mandible and nostrils orange- 

 yellow ; legs, feet and claws pale reddish-horny. 



Measurements. Length about 165 mm.; wing 70 to 78 mm. ; 

 tail about 75 mm.; tarsus about 15 to 16 mm.; culmen about 

 13 to 14 mm. 



Nidification and Habits. According to Davison this Bulbul 

 differs in no way from the various races of P. plumosus. 



The few eggs of which measurements have been obtainable 

 measure about 21-0 x 15-9 mm., but a larger series would certainly 

 give a smaller average for the eggs of this small bird. 



Genus MICROTARSUS Eyton, 1839. 



The genus Microtarnu may be recognized by its very ample and 

 lengthened tail-coverts, rounded tail and the extraordinary 

 development of the feathers of the lower back and rump, which 

 are moreover barred with black; in this respect Microtarsus 

 shows great affinities to Pinarocichla. 



In this genus the feathers of the head, though erectile, are 

 exceedingly short and glossy. The bill is about half the length of 

 the head, and the rictal bristles are well-developed. The tarsus 

 is very short but fairly stout. The plumage of all the known 

 species is very pleasing. 



* Sharpe shows that P. piisillus of Salvador!, 1874, is preoccupied by 

 Gray, Genera Birds, i, p. 237. and cannot be used. He therefore proposes 

 (Cat. B. M., 1881, Appendix, p. 401), P. salvadorii, but though this stands as 

 the name for the Sumatran race, erythropthalmus of Hume has priority as the 

 specific name.
