hides rufo-brunneae. Rostrum brunneum ; vmndibuld infe- 



riori ad basin flava. Longitude corjwris 4 V unc, candce SiV- 



Sexes do not differ in size or plumage. Habits of Prin. socialis. 



Both the above species are remarkable for a struggling flight, 



as if they experienced difficulty in making their way. 



Genus Orthotomus, Horsf. Tailor Bird. 



80. Orthotomus Bennettii. Orth. olivaceo-viridis; suhtus albidus; 



capite supra Jerrugineo ; caudii elongatd obsolete Jasciatd. 



Jrides flavae. Longitudo corporis 6 unc, candce 2^^- 

 Two central tail-feathers elongated beyond the rest for one inch, 

 and two-tenths of an inch wide only. Sexes alike. This bird 

 is very remarkable for the ingenuity shown in constructing its 

 nest by sewing the leaves of trees together with cotton thread 

 and fibres. Colonel Sykes has seen nests in which the thread 

 used was literally knotted at the end. This species very closely 

 resembles Dr. Horsfield's Orth. Sepium, but on a comparison of 

 the birds they were found to have specific differences. 



81. Orthotomus Lingoo. Orth. olivaceo-brunneus, subtiis sordide 



albus. 



Longitudo corporis 5tV unc, caudce 2 V- 

 This species differs from the type of Orthotomus in the short tail, 

 but has the characters of the genus sufficiently marked to be 

 included in it. Sexes exactly ahke in plumage. Principal food 

 black ants. 



Genus Budytes, Cuv. 



82. Budytes citreola. Motacilla citreola. Lath. This is the variety 



A. of Mot. citreola of Dr. Latham, vol. 6. p. 330. 

 Length 6tV inches: tail 2iV- 

 This bird so closely resembles the European species that Colonel 

 Sykes has not ventured to separate it. It has the habits of a 

 Motacilla, but its long hind claw sufficiently distinguishes it, 

 and M. Cuvier has facilitated research in forming a genus for 

 such JVaortails as have this claw. 



83. BuDYTES MELANOCEPHALA. Bud. oUvacco-viridis ; corpore 



subtus nitide Jlavo ; capite, nucha, rectricibusque nigris, harum 

 duabiis lateralibus alba marginatis ; alisjiiscis, plumis olivaceo- 

 Jlavo notatis. 



Irides intense rufo-brunneae. Longitudo corporis 6-rcr unc, 

 caudre 3, 

 These are solitary birds, and are rarely found, excepting in the 

 beds of rivers. In seven specimens four birds only were exa- 

 mined, and they happened to be males; so that Colonel Sykes 

 is uncertain with respect to the female. 



84. BuDYTES Beema, Bud. olivaceo-viridis, subtiis Jlavus ; capite 



supra griseo ; strigd superciliari alba ; alis J'uscis plumis fla- 

 vescenti marginatis ; caiidd atrd, rectricibiis duabus latera- 

 libus albis.
