| BANGS — SUBSPECIES OF MANACUS MANACUS 35 
Adult female: Upper parts green (about between olive green and parrot 
green); primaries and inner webs of secondaries dusky; under parts pale 
green, inclining toward olive yellow on belly and under tail-coverts, and toward 
pea green on throat. 
Size—An adult male from Demerara, no. 55,160, U. S. National Museum 
coll.: wing, 51.4; tail, 30.8; tarsus, 21.6; exposed culmen, 9.4mm. Six adult 
males range as follows: wing, 49.2-52.; tail, 29.6-31.8; tarsus, 2021.6; 
exposed culmen, 9.4—10.2 mm. 
Remarks.—True M. manacus appears to reach the height of its 
development in Trinidad, birds from that island being constantly 
more different from the Colombian form than are birds from the 
Guianas. Two skins from Guyaquil, Ecuador, are rather more 
like true AZ, manacus than like MW. m. abditivus. One skin from 
Pebas, Ecuador, is, however, perfectly typical of the latter race. 
‘These three specimens are all I have seen from the western part 
of the range of the species; they would appear to indicate that 
intergradation takes place somewhere in this vast general region. 
Manacus manacus abditivus' subsp. nov. 
Type, from Santa Marta, Colombia, ¢ adult, no. 5310, coll. of E. A. and O. 
Bangs, collected Jan. 13, 1898, by W. W. Brown, Jr. 
Geographic distribution.— Colombia — both the Santa Marta and the Bogota 
regions —and northwestern Venezuela, and thence westward. Exact limits of 
range unknown. 
Subspecific characters.— Adult male, similar to AZ. manacus manacus, but 
abdomen and breast, ending in an even line at jugulum, always pale gray, 
varying in intensity from pearl gray to gray, no. 7, of Ridgway, these parts 
being white in AZ. manacus manacus. In size it averages rather larger, with a 
shorter tail, than JZ. manacus manacus. 
Size.—Type, & adult: wing, 53.8; tail, 29.8; tarsus, 21.; exposed culmen, 
10.2mm. Twelve adult males range as follows: wing, 49.4-53.8; tail, 27.6- 
30.; tarsus, 20.-21.8; exposed culmen, 9.8-10.2 mm. 
Remarks.—The gray, instead of white, breast and belly of JZ 
m. abditivus, and its slightly larger size and shorter tail, separate 
it from AZ. m. manacus. The darker examples of JZ. m. abditivus 
bear a close resemblance in color to the paler examples of JZ. m. 
1 A dditivus — separated from.
