Bill longer than the head, conical, straight, and acute. Culmen, from region of the nostril 

 to the forehead, much compressed ; from nostril to apex swollen and flattened. Nostrils pro- 

 tected by a scale-like cover and shaded by dense nareal tufts. Commissure almost straight.

Sphenocichla eoberti, n. sp. 



General coloration throughout dark umber-brown, richer on the wings and tail, which are 

 closely barred with black ; feathers of the nape and back edged with darker brown, and with an 

 inconspicuous pale spot near tip ; these spots are more defined on the side of the neck. The

 markings ; towards the abdomen these become less conspicuous, and only a few white spots dot 

 the flanks. Bill grey, pale beneath and at tip.

Shot on Hemes Peak, North Cachar hills, and also in the Munipur hills. 



This anomalous form has the structure of a Turdinus and the bill of a Stacliyris. 



ACRIDOTHEEES ALBOCINCTUS, n. sp. 



Top of head glossy black, feathers rather elongated, and a white collar on back of neck ; 

 back dull grey-black, with a slight green tinge, and with a tendency to purple on the shoulders

 albescent. Between the eyes and the rictus black. A well-defined streak extending from above 

 the eye down each side of the head, fulvous. Ear-coverts cinereous at base, brown towards the
