 Chamepelia passerina neglecta Carriker, Ann. Carnegie Mus., VI, 1910, 398 

 (Esparta [type locality], Alajuela, San Jose, Bagaces, Bebedero, Cachi, Tenorio, 

 Coralillo, Los Cuadros de Irazii, and Miravalles, Costa Rica; orig. descr.; type 

 in collection Carnegie Museum; habits; Costa Rican references). 



Siibspecific characters. — Similar to C. p. pallescens, but male of a 

 much deeper vinaceous color below, more as in C. p. passerina; above 

 much darker, being dull brownish olive with a faint vinaceous shade. 

 Similar also to C. p. passerina, but decidedly browner above; sides of 

 head and neck averaging deeper pinkish vinaceous; wing-coverts more 

 extensively pinkish vinaceous, and bill reddish at the base. Not so 

 deeply or so uniformly brown above, however, as in C. p. socorroensis. 

 The under tail-coverts average darker, with deeper vinaceous edgings, 

 than in C. p. pallescens. The female differs in a corresponding manner, 

 being intermediate in general coloration between C. p. pallescens and 

 C. p. socorroensis. 



Measurements. — Male: wing, 85-89 (average, 87); tail, 53-60 (56); 

 exposed culmen, 11-12 (11.5); tarsus, 16-16. 5 (16. 1). Female: wing, 

 84-89 (86); tail, 52-60 (57); exposed culmen, 11-12 (11.7); tarsus, 

 15-16.5 (15.6). 



Range. — Central America, from Panama (?) north to Guatemala; 

 straggling occasionally to Yucatan. 



Remarks. — Messrs. Salvin and Godman were the first to call 

 attention to the peculiarites of this form, remarking that a skin from 

 Costa Rica was very similar to the Socorro Island bird. It seems 

 sufficiently distinct from C. p. pallescens, with which until recently 

 it has been confounded, to deserve a separate name. When a series 

 is compared the differences stand out prominently, and are fairly 

 constant. Unfortunately only a few specimens from any of the 

 Central American countries except Costa Rica have been available for 

 examination, but I should refer all I have seen to this form, including 

 two from Guatemala and one each from Merida, San Ignacio, and 

 Chichen-Itza in Yucatan. These more northern examples, however, 

 are not typical, indicating that intergradation with C. p. pallescens 

 takes place in this region. The specimens in question average duller 

 vinaceous below and slightly paler above than Costa Rican birds. 



Curiously enough, the only Panama record for any form of C. 

 passerina is a doubtful one, based on a specimen said to have been
