THE Turdus cyaneus is nearly allied to the Turdus varius, which was de- 
scribed in the Second Number of these Researches. Both birds belong to the 
Sylvains of M. Temrainck, which constitute the first section of this genus. Like 
the Turdus varius, our bird never descends into the plains, but conceals itself in the 
forests which cover the mountains and hills, from an elevation of 4000 to 6000 feet 
above the level of the ocean. It has a more extensive range than the Turdus varius, 
but it is very rarely observed, living retired in the closest forests. During my 
residence in Java, I obtained only three individuals of this species. Its food 
consists almost exclusively of berries. 
This bird, the Turdus varius, and several other species of Turdus from the 
Eastern Islands, have an affinity, which has been pointed out concisely in the
