and nape duller, paler, more restricted, and less distinctly squamate. 

 Darker, as well as decidedly larger, than C. p. nana, and with the 

 plumbeous area of the crown and nape usually indicated, although 

 much fainter than in any of the other forms, except C. p. nana and 

 C. p. griseola. Female above more grayish, less brownish, than in 

 C. p. neglecta, and slightly paler below, but only to be distinguished 

 from the same sex of C. p. nana by its larger size. 



Measurements. — Male: wing, 82-88 (average, 84.5); tail, 54-62 

 (59) ; exposed culmen, 10. 5-1 1.5 (11); tarsus, 16-17. 5 (16.3). Female: 

 wing, 81-86 (83.5); tail, 54-60 (56.5); exposed culmen, 11 ; tarsus, 

 16-17 (16.3). 



Range. — Western Ecuador and Peru (?), up to an altitude of about 

 ten thousand feet. 



Remarks. — With a series of thirty-two skins of the Ecuador bird 

 available its subspecific distinctness is readily apparent. From its 

 neighbor on the north, C. p. nana, it is easily distinguishable by its 

 larger size and different coloration, although it is probable that when 

 the intervening region shall have been worked over intergrades will 

 be found. To the eastward it probably passes into C. p. griseola. 

 The exact limits of its southern range are at present unknown, none 

 of the Peruvian records above quoted being above suspicion, while 

 its occurrence so far south as Chili, as recorded by Molina, is ex- 

 ceedingly doubtful. With the exception of Taczanowski, none of 

 the authors who have written on the birds of Ecuador or Peru seem 

 to have recognized the peculiarities of the Ground Dove of the region, 

 which is well worthy of subspecific segregation. 



Some of the skins show a faint lavender-gray cast, as in C. p. albi- 

 vitta, and the series otherwise exhibits the usual variations. A young 

 bird taken from the nest on April 1, 191 1, at Riobamba, is covered 

 with whitish down, borne on the ends of the growing feathers. None 

 of the specimens examined have the colors of the soft parts indicated, 

 but a number of them show a decided indication of red or yellow at 

 the base of the bill in the dried skin.
