C. cyanopolius, Blyth, from the Malay peninsula and islands, is a much brighter bird than C. unicolor, and may be kept distinct.

Habits, &c. Mandelli found the nest of this bird in Sikhim in August, a cup of moss and fern-roots placed in a depression in the trunk of a tree about 10 feet from the ground.

* Count Salvadori thus describes the specimen :—

" Supra olivacea, pileo et cervice griseis ; uropygio et supracaudalibus branneo-rufescentibus ; fronte, lateribus capitis et gula rufo tinctis, gula ima albicante; gastraeo reliquo griseo-olivaeo, pectore magis olivasente subcaudalibus et subalaribus fulvescente-albidis; alis fuscis, externis brunneo-olivaceo marginatis; cauda brunneo-rufescente ; rostro nigro; pedibus fuscis. Long, tota 0m,200; al. 0m, 096; caud. 0m,077; rostri culm 0m,010: tarsi 0m,020."
