CEBASOPHILA. 373 



Himalayan form in being more weald v marked, less handsome 

 eggs and also in being generally a shorter, blunter oval. Thirty 

 eggs average 26-6 x 19'5 mm. and vary in length between 28'3 X 

 19-3 mm. and 25'Ox 19-2 mm. and in breadth between 27'0 x 20'6 

 and 26-3 x 19'0 mm. They breed from February to July. 



Habits. Those of the genus. They are never found in the 

 plains and seldom below 2,000 feet, even in winter. Mr. Rhodes 

 Morgan records having seen these Bulbuls "migrating in vast 

 flights, numbering several thousands, in the Bolumputty Valley 

 in July. They were flying westwards towards Malabar." 



They frequent both the outskirts of forests and heavily-wooded 

 districts and also small spinneys and sholas standing in the 

 hollows of grass-covered hills. 



Genus CERASOPHILA Bingham, 1900. 



This genus was created by Bingham for the reception of a very, 

 remarkable Bulbui, probably nearest to the genus Microscelis 

 (Hypsipetes auct.). Like that genus the tarsi are short and non- 

 scutellate and the tail is rather long and forked. The culmen 

 is more curved than in Microscelis but it differs principally from 

 that genus in having a bare unfeathered patch of skin round the 

 eye. The under tail-coverts are brightly coloured as in Molpastes 

 and Otocompsa.
