152 Bangs Seven New Subspecies of American Birds. 



MEASUREMENTS. 



Remarks. This form, which replaces true soui of Guiana and Venezuela 

 in the Santa Marta region of Colombia is much more brightly colored than 

 the typical form, and judged from the plate and descriptions is not unlike 

 C. caslaneus Scl. in color. That it is not that species, but a member of the 

 soui series, is shown by its whitish throat and smaller dimensions. 



I have seen several specimens from Guiana and have one adult 9 taken 

 by Capt. Wirt Robinson at San Julian, Venezuela, that is just like them. 

 In fact, Plate 829, of d'Aubenton's Planches Enlumineez, on which Cr>/i>- 

 turus soui was based, could not be more like this specimen, if it had actually 

 been taken from it. 



Crypturus soui mustelitius needs no comparison with the dark-necked 

 form C. soui modestus that occurs just north of it in Panama. I have seen 

 no males of the new form, but undoubtedly they would be much darker 

 and duller than the females as is the case with most species of Crypturus. 



Scardafella inca dialeucos subsp. nov. 



NICARAGUA SCALED DOVE. 



Type from the boundary line between Honduras and Nicaragua, 180 

 miles from Pacific coast.* No. 4796, coll. of E. A. and O. Bangs. 



Characters. Somewhat similar to true S. inca of Mexico, etc., but larger 

 wing coverts grayish white in marked contrast to rest of coverts ; under- 

 parts more distinctly barred with blackish, the bars extending over the 

 entire breast, though less distinct as they reach the throat; vinaceous of 

 breast much paler and more restricted, the buffy white of belly reaching 

 farther forward. Similar also to 8. ridgwayi f of South America, but upper- 

 parts much darker, with the dusky squamatulations less distinct; light 

 patch on wing not so white; and underparts less heavily barred with 

 blackish. Size as in S. inca inca. 



Measurements. Type: Wing, 89; tail, 90.5; tarsus, 16; culmen, 15. 



Remarks. Scardafella inca inca ranges from southern Arizona and Texas 

 through Mexico and Guatemala, with but little if any geographical varia 

 tion, but at the very southern extremity of its range gives place to a race 

 that in all the points of difference from the northern form approaches S. 



* The type is one of a collection* of birds which was bought by me some years ago 

 from an engineer who had been engaged in work on the boundary line between Hon 

 duras and Nicaragua. The specimens were all taken at one point in summer and early 

 autumn. 



t Dr. Richmond has pointed out that, even if S. ridgwayi of Margarita Id. is not con 

 sidered a valid form the name must hold for the species, Columba squamosa Temm. and 

 Knip. being preoccupied.
