nostrils large, naked, corneous, aperture small,
linear, lateral. Wings and tail very short,
rounded. Legs very long, slender; the anterior
and lateral scales divided; inner toe short.
Claws small, slender, not much curved.
Inhabits India. Three species, not described. One of
these is in the British Museum, the others are at Paris.

lateral toes equal. Tail divaricated, the tips

Type.—Sylvia rubecula, Atjct.
^ BS* I am notJ at present, prepared to offer any opinion on the extent of this genus, which seems to be the Fissi-
rostral group of the Saaicolinoe. Sialia and Petrcnca are probably two of the sub-genera, the first distinguished by
the structure of the wing, the other by that of the foot. Sylvia rubecola may possibly constitute genus Saxicola. the passage to the

the 3d, 4th, and 5th equal and longest.
Legs slender. Tarsus with entire scales.
Inner toe rather shorter than the outer. Tail

Rostrum integerrimum, lateribus compressis,
inflexis.; culmen .-ei basi arcuatum, sed ad
nares non gibbum. Rictus angulatus. Alae

cundarias superantes, remex quarta, quinta, et
sexta cequales, longissimceque. Tarsi squamis

Bill entire, the sides • compressed and in-
flexed, culmen curved from the base, but not
gibbous • at the nostrils. Rictus angulated.
Wings short, much • rounded, the greater
quills scarcely longer than the lesser ; the 4th,
5th, and 6th equal and longest. Tarsi with
divided scales. Tail rounded; the feathers
very obtuse, and generally black.

placing this form with the S a x ic o lih m , or
the. latter sup-
Type.—Th. rufiventer, Sw. (Le traquet à queue striée, Le . Vail l.,, pi. 188).
Obs.—I cannot state, from analysis, - whether Le Vaillant is correct in
whether it is not a subgenus oîPhoenicura. There. are reasons, however, which lead me to adopt
position. The type clearly corresponds to Linaria, Brachypus, Parisoma, &c. &c.
22. Sub-genus, DUMECOLA. (Generis Sylvicolæ.)
Rostrum basi latum, lateribus compressis,
apice aduncum et emarginatum, vibrissis di-
vergentibus basi cinctum. Alse medioerqs;
remex prima, secunda, et tertia leviter gradates.
Cauda divaricata, rectricibus acumirie
tenui desinentibus. Ungues validi valde curvati
; unguis posticus magnus medium longitudine
eequans. Digiti laterales inequales.
Typus.—D. ruficauda, supra olivacea, subtus fulva;
capite, cervice guloque in mare cinereis ; caudd et tegmi-
nibus ejus superioribus fulvo tinctis.
Bill wide at the base, the sides compressed,
the tip abruptly hooked and notched, the
base surrounded with diverging bristles.
Wings moderate, the first, second, and third
quills slightly graduated. Tail divaricated, ending
in fine points. Hinder toe and claw large,
as long as the middle; lateral toes unequal.
Claws strong, much hooked.
Type.—D. ruficauda, above olive, beneath fulvous*
head, neck, and throat, in the male, cinereous; tail and
upper covers tinged with fulvous.
Obs,—Having seen but one species of this form, I venture to characterize it with much doubt, since I suspect that the
true fissirostral type of <Syfoico/a is the AfMscicapoDyops of Temminck, PI. col. 144, f, I. Dumecola ruficauda closely resembles
a very small Tyrannula, except in its feet, which agree with this genus in being long,—the tarsus measuring, from the
knee to the sole, nine-tenths of an inch. I have recently received from Mexico a bird, which seems more intermediate between
Zoster ops and Sylvicola, than either Dumecola or the Sylvia mitrata. of Wilson, This latter, from its close resemblance,
in a young state, to Mniotilta pinus, might lead us to suspect it entered in the same circle. When such minute
analysis is gone into, we feel it necessary to express all our doubts ; nor can these be dispelled until the genus Seta-
phaga has been carefully studied, and its different forms defined.
