the female of C. / ensis, while the brown color oi the under 



parts has a fainl wash of cinnamon, especially on the breast, fn 

 both sexes the pale edgings ol the throat and breasl are narrower, 

 giving the parts a decidedly more squamate appearance. 



Measurements. — Male (two specimens): wing, 75 77 . 76); 



tail, 54-55 (54.5); exposed culmen, to [0.5 (10.2); tarsus, 15. Fe- 

 male (one specimen): wing, 73; tail, 51 ; exposed culmen, 1 1 ; tarsus, 15. 



Range — Known only from the type locality, Honda, Colombia, and 

 it-- vicinity, bu1 probably occupying a more or less extensive area in 

 central Colombia. 



Remarks. — The above description is based on a single pair of birds 

 in the collection of the U. S. National Museum, which are so very 

 different from any of the other known forms that I have no hesitation 

 in describing them as new. Ik-sides these I have examined one other 

 specimen, collected by Mr. Louis A. Fuertes on a recent trip to 

 Colombia. This example is somewhat different from the type, not 

 being so dark, but the breast is as finely squamate, while the feathers 

 of the nape have- decided dark edgings of a sooty plumbeous color. 

 The thin and forehead are almost as pale as in C. p. albivitta, and the 

 under tail-coverts also are quite pale. The back is somewhat brown- 

 ish, and the crown decidedly so, while the wing-coverts are of the 

 same shade of color as the breast. Judging by analogy from the dry 

 skin, the bill was evidently red for the most of the lower half, and the 

 upper mandible wholly dark, except at the extreme base of the com- 

 missure. These differences are not more than are fully covered by 

 the usual range of individual variation obtaining in the present 

 species, but additional specimens are of course very desirable. 



Although in color this form is most like C. p. socorroensis, its real 

 affinities would appear to be rather with ( '. p. griseola, while the limits 

 of its range, when more fully worked out, will possibly be found to 

 approximate those of the latter. Lieutenant Wirt Robinson tells us 

 that (.round Doves were common at Honda and Guaduas, on the 

 road to Bogota, and gives the impression that the species was not seen 

 between Barranquilla (on the coast) and Honda. Count von Ber- 

 lepsch, indeed, has published a record for ChamcBpelia passerina from 

 Bucaramanga, Colombia, but the measurements appended show 

 that his bird could not possibly belong to the form here described. 

 Should future work determine that the species does not range over 

 the intervening country it would tend to explain the development
