THE BIRDS OF THE NATUNA ISLANDS 



105 



Although we have seen specimens of this subspecies from only 

 Sirhassen Island, it probably occurs on other southern islands of the 

 Natuna group. 



Doctor Abbott obtained the two following examples: 



Adult male (type), U.S.N.M. No. 174846, Sirhassen Island, June 

 5, 1900. 



Adult female, U.S.N.M. No. 174845, Sirhassen Island, June 5, 

 1900. "Feet leaden blue." 



Doctor Abbott reported it common in the thick jungle on Sirhassen 

 Island. The specimens collected show no indication of molt. 



Measurements are given in Table 35.

ARACHNOTHERA LONGIROSTRA ROTHSCHILDI van Oort 



Arachnothera longirostra rothschildi van Oort, Notes Leyden Mus., vol. 32, 

 no. 4, p. 195, Dec. 30, 1910. ["Natoena Islands (Boengoeran)."] 



Four specimens were obtained by Doctor Abbott: 



Adult male, U.S.N.M. No. 174844, Pulo Lingung, near Bungu- 

 ran Island, June 16, 1900. "Feet leaden blue." Length in flesh, 

 152 mm. 



Juvenal male, U.S.N.M. No. 174841, Bunguran Island, July 3, 

 1900. "Feet leaden blue; upper mandible black; lower mandible 

 dark horn brown, at tip brownish, pale greenish leaden toward 

 base." Length in flesh, 156 mm. 



Adult male, U.S.N.M. No. 174842, Bunguran Island, July 18, 

 1900. Length in flesh, 152 mm. 



Juvenal male, U.S.N.M. No. 174843, Bunguran Island, July 22, 

 1900. Length in flesh, 152 mm. 



All these examples show more or less evidences of molt — the 

 adults in both quills of wings and tail and in contour feathers; but 

 the juveniles only in the contour feathers. The two ju venal males 

 differ very little in coloration from the adults, and chiefly in the 

 slightly darker more greenish shade of the upper surface. All our 

 birds bear out the distinguishing characteristics of Arachnothera 

 longirostra rothschildi. 



Measurements are given in Table 36.
