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: — 



1st species, flaviventer, mihi. — Above deep grass-green, below 

 rich yellow ; cap bright chestnut ; legs fleshy grey ; bill dusky above, 

 fleshy below ; iris brown. Length, 3| inches ; bill, -^ ; tail, 1 ; 

 wing, IJ ; tarse, \^ ; central toe and nail, \^ ; hind, plus i. 



2nd species, cyaniventer, mihi. — Above grass-green, below slaty 

 blue ; legs and feet smoky grey ; bill dusky above, horn below. 

 Length, 3| inches ; bill, \^ ; tail, \^ ; closed wing, less 2 ; tarse, 1 ; 

 central toe and nail, W ; hind, ^. 



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 Cinclus. Our Horor- 

 nis and Monticola are analogous forms among the Sylviance, and Todus 

 among the Muscicaps. Gould has figured our first species of Tesia, 

 which he calls Micrura squamata, 



Sylviad^. 



Saxicolinje. 



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, Digetiea, 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 falcate and short. 



Types, D. sirophiata, monileger and rubrocyanea. D. strophiata 

 printed apud Indian Review, quod vide. 



D. ? monileger, mihi. — Above olive-brown, sordid, save on the 

 wings and tail ; below diluted and sordid ; frontal zone rusty ; chin
