COPSYCHUS SAULARIS subspecies 



Copsychus saularis Chasen and Kloss, Ibis, 1926, p. 291. 



Two iinsexed examples, Siberut. 



The above two specimens are apparently females in molt, and one 

 is certainly a bird of the year, as it still retains some of the spotted 

 feathers on the side of the throat. Both have rather small bills (19 

 and 19.5 mm.), much smaller than the still younger female that I 

 have assigned to pagiensis. It is possible that there are two forms 

 of this thrush occurring together on Siberut, and possibly on Sipora 

 (the female assigned to pagiensis with the culmen 20 mm.). Should 

 this prove to be the case, pagiensis would be entitled to full specific 

 rank. 



Two other races have been described from islands off the west 

 coast of Sumatra, namely : 



Copsychus saularis zacnecus Oberholser, Simalur Island, and 

 Copsychus saularis nesiarchus Oberholser, Nias Island. * 



Both are small-billed forms like the present. The Simalur bird with 

 a culmen 21-20 mm. in the male ; 19.5 in the female. The Nias bird, 

 18-21 mm. The two forms are much alike and may eventually have 

 to be united under the older name proposed for the Simalur bird. 

 They were originally established on scanty and insufficient material, 

 consisting of two males and one female from Simalur and two males 

 from Nias.

One adult male, tAvo immature males, and one female, Sipora ; 

 one young male, Siberut. 



The type of Kittacincla tnelanura pagiensis Oberholser, is a bird of 

 the year molting into the adult plumage. It is matched in size by 

 the immature males from Sipora and fairly well as to color. The 

 form was founded on the single specimen. The adidt male from 

 Sipora can not be distinguished in color or size from a series from 

 Nias ; the bill is a little longer but not enough to be significant in a 

 single specimen. Allowing for seasonable differences, I can not detect 

 any characters that will separate the Simalur and Pulo Lasia and 

 Pulo Babi birds from that of Nias. In other words, as far as our
