- Type. 



Piilo Kalambau is one of the largest three islands of the Laurot, 

 •or Laut Kitchil, Islands, in the eastern portion of the Java Sea. 

 It lies in the southern part of tnis group, and about 90 miles soutti 

 of the eastern end of southern Borneo. 



Doctor Abbott landed here for a day on December 7, 1907, and 

 collected two birds, which he as usual presented to the United States 

 National Museum. These represent two species, and one is an unde- 

 scribed subspacies. So far as we are aware no birds have ever 

 been recorded from Pulo Kalambau, Those collected by Doctor 

 Abbott are siven below. 



Family RALLIDAE. 



GALLICREX CINEREA (Gmelin).

Doctor Abbott obtained a single specimen, an adult female, 

 No. 181400, U.S.N.M., December 7, 1907. Length (in flesh), 350 mm. 



This example is in perfect plumage, but appears to exhibit no 

 significant differences in either size or color from Chinese or Philip- 

 pine birds, though it is somewhat smaller than any of our limited 

 series of specimens from the Philippine Islands.
