ILLUSTRATIONS OF ORNITHOLOGY. 
Mr. Blyth, the curator of the Calcutta Museum, who has most 
zealously pursued the zoology of India, has lately forwarded to us 
a series of drawings of those species which run most into the 
European forms. Many of these are very remarkable, and in- 
crease genera to several species, which previously contained only 
a single one, or were extremely limited. These drawings are 
executed by a native artist, very minutely and accurately, hut in 
most instances with an Indian mannerism ; nevertheless, we have 
thought it better to give, as far as possible, fac-similes of them, 
than to attempt to introduce accessories. They will appear from 
time to time, and will have the advantage of Mr. Blyth’s remarks. 
ERYTHACA FLAY OLIYACE A, Hodgs., Fig. 1. 
Nemura flavolivacea, Hodgs., in Proc. Zool. Soc., 1845, p. 27. Ianthia flavolivacea, 
Blyth, in Journ. As. Soc. Beng., vol. xvi. p. 133, 474. 
The genus Erythaca, typified by the common Robin of Europe, 
has hitherto been very limited in extent, containing, besides the 
type, only one or two little known species from the Japanese 
Islands ( Sylvia akahige , and perhaps S. komadori of Temminck, 
Ph Col. 570, 571). The researches of Mr. E. Blyth, Curator of 
the Asiatic Society’s Museum at Calcutta, have, however, brought 
t° tight at least one more species of genuine Erythaca .” 
This bird is thus described by Mr. Blyth: — “ Upper parts Uni- 
term fulvescent olive ; loral region and throat, rufescent white ; rest 
°f lower parts dilute rusty ; beak dusky ; base of lower mandible 
Pale; legs pale. Total length, 5.5; wing, 2.8; tail, 2.3; tarsus, i.I.” 
He adds, in a note accompanying the drawing, “ I consider this 
f lull coloured species to be a typical Erythaca , having merely the 
hill somewhat more slender than in the European bird ; and I have 
little doubt that the sexes will prove to be similar, as all that I 
have seen have been alike.” 
Inhabits Nepal and Darjeeling.
