 CoUocalia nidifica Gray, Genera Birds, I, 1845, p. 55 (Sumatra). 



Chars, suhsp. — Similar to CoUocalia fuciphaga fuciphaga, but entire 

 lower surface much paler; upper parts rather lighter and more 

 brownish. 



Type locality. — Sumatra. 



Geographical distribution. — Sumatra, Simalur Island, and southern 

 part of Malay Peninsula. 



The original CoUocalia fuciphaga was based on the bird from Java, 

 from which this western form differs as above said. For the latter the 

 name Salangana vestita Lesson ^^ seems to be available. This is 

 founded on " Hirundo esculenia Lath. Gen. Syn. pi. Hab. les iles de la 

 Malasie," ^^ which in both description and locality (Sumatra) is perti- 

 nent to the present form. Moreover, the only Sumatran specimen 

 examined agrees with the birds from Simalur Island, upon which latter 

 the present separation is primarily based. The Nias Island bird, how- 

 ever, is identical with that of Java, as already noted, and therefore 

 must be called CoUocalia fuciphaga fuciphaga. A single adult from 

 Tanjong Silantei, on the east coast of Johore, southern Malay Peninsula, 

 seems to be exactly like the birds from Simalur Island in color, but is 

 considerably larger, the wing measuring 118 mm. ; notwithstanding this 

 it seems best referred, for the present at least, to C. f. vestita, although 

 additional specimens may show it to be representative of a recognizable 

 subspecies. 



Measurements of CoUocalia fuciphaga vestita are as follows :
