DISTRIBUTIONAL LIST OF SPECIES AND SUBSPECIES. 

 Obdee TINAMIFORMES. ' 

 Family TINAMID^E. Tinamous. 



(4) 1 Tinamus tao Temm. 



Tinamus tao Temm., Pig. et GaUin., Ill, 1815, pp. 569, 749 (Parii, Brazil). 



One was shot by Fuertes in the dense subtropical forest of the Western 

 Andes. 



San Antonio, 1 (Fuertes). 



(7) Tinamus major ruficeps Scl. & Sah. 



Tinamus ruficeps Scl. & Salv., Nomen. Av. Neotr., 1873, p. 162 (Rio Napo, 

 Ecuador); P. Z. S., 1879, p. 548 (Remedios); Allen, Bull. A. M. N. H., XIII, 1900, 

 p. 124 (Cacagualito). 



Inhabits the Tropical Zone of the lower Cauca and lower Magdalena. 

 Study of our forty specimens of this group from northern South America 

 and Central America, convinces me that the various species which have 

 been described from this area are representative, intergrading, geographic 

 races of one species. None of the characters assigned to these forms proves 

 to be of true specific value. Color, pattern of marking, and length of crest 

 are all shown by our series to vary with locality, and, when the material is 

 adequate, it indicates that the various forms merge into those which, geo- 

 graphically, are nearest to them. 



Of T. m. ruficeps we have, unfortunately, only one specimen which can 

 be considered as approximately topotypical, a male collected by Miller at 

 La Morelia. It differs from other Colombian specimens, which I refer to 

 this race, in having the inner wing-quills and upperparts more heavily 

 barred, but in this respect it is matched by specimens of castaneiceps from 

 the Atrato. The crown is brighter than in five Antioquia specimens but 

 agrees in color with that of a bird from Santa Marta. 



1 The numbers in parentheses preceding each species are those of Brabourne and Chubb's ' Birds of 

 South America.*' When this number is followed by a letter, it indicates that the species in question 

 is not contained in Brabourne and Chubb's work.
