REVISION OF THE CLAPPER EAILS OBERHOLSER 335 



more brownish (less grayish) upper surface, the feather centers there 

 much less blackish and much lighter; less grayish (more brownish) 

 low^er surface, the anterior parts being duller and more uniform 

 ochraceous buff. 



In this race the jugulum is slightly but more or less evenly washed 

 with grayish, making the color of this part rather dull. All the 

 specimens that the writer has seen are in what might be taken for 

 the brown phase, as there are no grayish birds among them. 

 Specimens from the subjoined locahties have been examined: 

 Jamaica: Near Spanish Town-^; Great Salt Pond (January — , 

 1865). 



RALLUS LONGIROSTKIS PALLIDUS Nelson 



Yucatan Clapper Rail 



Rallus pallidus Nelson, Proe. Biol. Soc. Washington, vol. 18, p. 141, June 9, 1905 

 ("Rio Lagartos, Yucatan, Mexico"). 



Subspecific characters. — Similar to Ralhs longirosfris carihaeus, but 

 upper parts decidedly lighter; flanks darker; and the cmnamon of 

 lower surface more pinkish (less ochraceous). 



Measurements. — Adult female ^^: Wing, 143 mm; tail, 59.5; exposed 

 culmen, 53; tarsus, 48; middle toe without claw, 48. 



Type locality. — Rio Lagartos, northwestern Yucatan, Mexico. 



Geographic distribution. — Permanent resident in northern Yucatan 

 and eastern Quintana Roo, Mexico. 



Remarks. — This clapper rail differs from Rallus longirosfris crepitans 

 in haA-ing the bill shorter, upper parts including wings, particularly 

 the miesial stripes, and tail more rufescent (less grayish). It may be 

 separated from Rallus longirosiris corrius by the longer wing and 

 middle toe, and darker breast, flanks, and upper parts. The only 

 specimen known up to the present time is the type, but also the clapper 

 rail recorded from eastern Quintana Roo by Griscom belongs probably 

 to this race. 



rallus LON'GIROSTRIS BELIZENSIS, new subspecies 



Honduras Clapper Rail 



Subspecific characters. — Similar to Rallus longirosiris pallidus, but 

 upper surface, including the crown, very much darker, the dark 

 centers of the feathers blackish instead of olive brown, but the 

 edgings of the feathers lighter, more purely gray. 



Description. — Type, adult female, no. 19747, collection of E. A. 

 and O. Bangs; Ycacos Lagoon, British Honduras, May 14, 1907; 

 Morton E. Peck.
