The present specimen differs from the only one of the 
same sex from the Malay Peninsula with which we have been 
able to compare it, in having the upper surface of an azure, 
not cobalt or ultramarine blue, but differences of a similar 
nature occur frequently in specimens of the same species of 
Cyornts from the same locality and are apparently of no 
diagnostic importance.

The Malayan form of the Himalayan species, C. wnicolor, 
has of late years been generally regarded as separable on 
account of its smaller size and brighter colouration under the 
name Cyoriis cyanopolia which, however, Hartert has shown to 
be unusable as no description is attached to Blyth’s quotation 
of Boie’s MS. name in the Leyden Museum. 
In the same paper Blyth described a specimen in the 
Leyden Museum to which the MS. name of “ Musctcapa infus- 
cata, Mill” was applied, regarding it. as the female of Cyornts 
cyanopolia and this conclusion has been accepted by Hartert 
(tom. cit.) Unfortunately, however, Finsch (Notes Leyden 
Mus. xxii, p. 202 (1901)), on re-examination of the types of 
Muscicapa infuscata, has discovered that they are not referable 
to Cyornis at all but are the species known as Rhinomytas 
pectoralis, Salvad, which must accordingly be known as 
Rhinomyias infuscata (Blyth). However, in view of the fact 
that a description is attached to Hartert’s remarks on the 
present form, the name is still available for this Cyormis, and 
his Gunong Tahan specimen must be regarded as the type of 
the subspecies. 
With the exception of the above listed skin from Siolak 
Daras, the occurrence of this species in Sumatra has 
hitherto rested on Blyth’s notes on the Leyden Museum 
collections. 
It is, however, fairly common in Java and Borneo and 
also occurs, though not abundantly, in the Malay Peninsula. 
Five specimens from Perak and Selangor have a wing 
measurement of 74-78 and a tail of 66-72, agreeing well with 
Part II: Vertebrata.
