392 MR. R. B. SHARPE ON BIRDS FROM MADAGASCAR. [June 9), 
der surface of the body dusky olive-brown, yellowish down the 
centre; edge of the carpal joint yellowish white, bill horn-brown, 
the lower mandible yellow; feet horn-brown, claws pale yellowish 
brown. Totallength 6:2 inches; of bill from front 0°5 ; wing 2:4; 
tail 2°9 ; tarsus 0°8. 
The intensity of the yellow on the throat and olive-brown on the 
under parts varies in specimens. In the female bird mentioned by 
Mr. E. Newton (/. ¢.), and the specimen of which has been lent to 
me by Professor Newton, the throat is nearly white, the longitudinal 
marks on the upper part of the breast very distinct, and the abdo- 
men pale yellowish olive, all the colours being clearer than in the 
specimens in my own collection. 
I would here remark that Drymeca morelii, Pollen (Gray’s 
‘ Hand-list,’ no. 2748), is the present bird (/. c. no. 2845). This 
oversight, which was pointed out to me by Mr. Gray himself, is not 
due to any fault of his, as the following facts will show. In the 
course of last year Mr. Gray received from Mr. Pollen a specimen 
of Ellisia typica, labelled in Mr. Pollen’s own handwriting Drymeca 
morelii ; and being at work on his ‘ Hand-list’ at the time, he placed 
the bird in the genus Drymeca, supposing that the description was 
published in Holland aud would in due time make its appearance in 
this country. No description, however, appeared, the bird being 
afterwards recognized to be Hilisia typica* by Mr. Pollen; but the 
names had already been printed before the mistake could be rectified. 
Mysracornts (nov. gen. Sylviidarum). 
Rostrum gracile, elongatum, compressum, dertro recto, gonyde 
versus apicem paullo ascendente, setis rictalibus nullis ; naribus 
oblongis linearibus. 
Ale moderate, rotundate, remige primo brevi, secundo et tertio 
gradatim longioribus, quarto, quinto et sexto equalibus et lon- 
gissimis. : 
Cauda fere quadrata, rectricibus 10, mediis paullulo longioribus. 
Pedes graciles, tarso longo, haud scutellato ; digitis lateralibus 
subequalibus, exteriore ad basin medio conjuncto ; unguibus de- 
bilibus. 
This genus comes very near to Tatare and Macrosphenus, but has 
the bill more compressed, and may at once be distinguished by the 
absence of all rictal bristles. 
The name Mystacornis was suggested to me by Mr. G. R. Gray ; 
and I have adopted it, as it well expresses the configuration of the 
head of the typical species.

* Fxactly the same circumstances will account for Saaicola arborea, Pollen 
(Gray’s ‘ Hand-list, no. 3280), which is Newfonia brunneicauda (1. c. no. 4846), 
appearing in the ‘ TTand-list.’
