CERASOPHILA. 373 
Himalayan form in being more weakly 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 25:0 x 19:2 mm. and in breadth between 27-0 x 20°6 
and 26°3x19°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 Bulbul, 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 Microscelts 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 MJolpastes 
and Otocomps«.
