furnished with twelve plumes; the bill more depressed ; rictus less 
entirely smooth; nareal tect less developed and nares consequently 
ovoid; lateral toes unequal, hind large, and nails more acute. ‘Types, 
the following :— 
lst species, flaviventer, mihi.—Above deep grass-green, below 
rich yellow ; cap bright chestnut ; legs fleshy grey ; bill Ausky above, 
fleshy below; iris brown. Length, 32 inches; bill, s tail, 1: 
wing, 12; tarse, 13; central toe and nail, 12; hind, plus $ 
2nd species, cyaniventer, mihi.—Above grass-green, below slaty 
blue; legs and feet Srey grey; bill dusky above, horn below. 
Length, 32 inches ; bil 1¢ ; an +¢; closed wing, less 2; tarse, 1 ; 
peal ae and nail, 11; hind, 5%. 
Remarks.—The above genera were first discovered and described 
by myself, but I failed then to note the distinction between the two. 
I have now thrown all the prior and new species together. These 
singular birds are peculiar to the mountains, and dwell in moist 
woods where there is plenty of underwood ; they are solitary, silent, 
live and breed on the ground, and feed on seeds, gravel and insects ; 
their stomach is thick—almost a gizzard. They should stand with 
Aipunemia and Brachypterix, between Pitta and Cinelus. Our Horor- 
nis and Monticola are analogous forms among the Sylviane, and Todus 
among the Muscicaps. Gould has figured our first species of Tesia, 
which he calls Micrura squamata. 
SYLVIAD, 
SAXICOLINE. 
Dimorpha, mihi (see ‘ Indian Review,’ Siphia). 
Bill short, cylindrico-depressed ; Muscicapan, but less wide and 
less armed at the tip; base loaded with a forward soft zone, putting 
forth hairs which partly conceal the nares ; rictus less wide and less 
armed than in Muscicapa, but approaching thereto ; wings more or 
less elongated and acuminated, with 4th, 5th, or 6th quill longest ; 
the first three or four more regularly gradated than in Muscicapa; 
alar and caudal plumes wedged and mucronate, and the tail itself 
either slightly gradated from centre and sides, or cuneate ; legs and 
feet more suited to walking than in Muscicaps; tarse smooth and 
exceeding the mid toe and nail; toes medial, compressed, unequal ; 
hind sometimes large, but not broad; nails large and slender, or 
small and more bent. 
The subgenera seem to be three, or Dimorpha, Digenea, and Syn- 
ornis. 
Dimorpha 
proper, with long wings, having the fourth quill longest ; tail broad 
and gradate from centre and sides ; feet with the lateral fore-toes 
nearly equal and the hind-toe small, and the nails faleate and short.

D.? monileger, mihi.—Above olive-brown, sordid, save on the 
wings and tail; below diluted and sordid ; frontal zone rusty; chin
