FAMILY RALLIDAE 345 



ARAMIDES CAJANEA LATENS Bangs and Penard 



Aramides cajanea latens Bangs and Penard, Bull. Mus. Comp. Zool., vol. 62, 

 Apr. 1918, p. 41. (Isla del Rey, Archipielago de las Per las, Panama.) 



Characters. — Averaging smaller than typical cajanea and definitely 

 paler in color, especially on crown, neck, and under surface; brown 

 of breast and sides more cinnamon-buff, less rufous. 



Measurements. — Males (2 specimens), wing 168, 173; tail 57.5, 

 59.7 ; culmen from base 50.0, 51.8 ; tarsus 68.2, 69.0 mm. 



Females (2 specimens), wing 161.0, 172.0; tail 57.5, 63.8; culmen 

 from base 51.0, 51.5 ; tarsus 67.0, 70.3 mm. 



Resident. Archipielago de las Perlas (Isla del Rey, Isla Viveros, 

 probably Isla de Cafias, and Isleta Malaga). 



This race is known from the four specimens of the type series in 

 the Museimi of Comparative Zoology collected on Isla del Rey in 

 February and March 1904 by W. W. Brown. The statements of 

 characters and the measurements given above are from my personal 

 examination of these birds. Rendahl (Ark. Zool., 1920, p. 22) listed 

 a female taken on Isla Viveros, on April 4, 1882, by Carl Bovallius, 

 that is unquestionably this race as the bird is said to be paler on 

 the head, neck, and underparts, when compared with skins from 

 Surinam and Baia. From January 21 to 23, 1960, I heard wood rails 

 calling on several occasions on Isla Canas, which is separated from 

 the eastern side of Rey by a very narrow channel; and at Isleta 

 Malaga, immediately east of Isla Bayoneta, heard others on January 

 29. It is probable that these records refer to the race latens since 

 the islands listed lie on the same shallow submarine platform that 

 surrounds Isla del Rey. 



ARAMIDES CAJANEA MORRISONI Wetmore 



Aramides cajanea morrisoni Wetmore, Proc. Biol. Soc. Washington, vol. 59, 

 Mar. 11, 1946, p. 50. (Isla San Jose, Archipielago de las Perlas, Panama.) 



Characters. — Similar in small size to A. c. latens, but gray of 

 hindneck clearer, less brownish, and also darker ; back, wing coverts, 

 and scapulars darker, more olivaceous green. 



Measurements. — Males (6 specimens), wing 165-179 (174.3), tail 

 54.1-64.2 (58.3), culmen from base 46.8-58.7 (52.5), tarsus 64.2-71.0 

 (67.6) mm. 



Females (6 specimens), wing 161-173 (166.5), tail 54.5-56.8 (54.9), 

 culmen from base 48.0-51.9 (49.8), tarsus 62.7-70.0 (66.5) mm. 



Resident. Fairly common; islands of San Jose and Pedro Gonzalez, 

 Archipielago de las Perlas.
