Rails were collected both in swampy areas and well-drained up- 

 lands. Some birds were taken in the new growth of vines and other 

 low vegetation of the battle areas. Stomachs contained insects, seeds, 

 and small shells. Two males had enlarged testes.

Rails frequented forested parts of Guam. The birds were rather 

 secretive, many of the specimens being taken in rat traps. Black 

 downy young were observed on April i and May 16. One nest 

 containing three eggs was found in dense grass near Mount Santa 

 Rosa on October 24. The eggs are white with a pinkish cast and a 

 scattering of small spots of colors near "russet" and near "pearl 

 blue" which are concentrated at the large ends. They measure 37.5 

 by 29.1, 39.1 by 28.0, and 40.7 by 29.0. A male, taken in January, 

 had enlarged testes. Weights of two adult males were 256 and 257, 

 of two adult females 210 and 252. 



POLIOLIMNAS CINEREUS COLLINGWOODI Mathews 



Poliolimnas citiereus collingivoodi Mathews, Bull. Brit. Orn. Club, vol. 46, 

 1926, p. 60. (New name for ocularis Ingram "preoccupied as a synonym of 

 cinereus Vieillot.") (Philippine Islands, ex G. R. Gray.) 



McElroy found birds in brackish swamps at Truk. One male ex- 

 amined in December had enlarged testes. Although recorded from 

 many islands of Micronesia, birds were not found by our naval field 

 parties at the other islands visited. Service personnel reported a 

 small rail at Asor and Falalop Islands, Ulithi Atoll, in the early days 

 of occupation, but the bird was apparently eliminated as a result 

 of the naval activities.
