SCIENTIFIC EXPEDITION TO NORTHWESTERN COLORADO I4I 



615. Tachycineta thalassina lepida, Violet-green Swallow 



Found two pairs that had taken possession of an old dead tree near Marvine 

 Lodge, and saw several more between Fitzgerald's and Himes'. 



616. Riparia riparia, Bank Swallow 



617. Stelgidopteryx serripennis, Rough- winged Swallow 



At various points numerous swallows, which I took to be one or both of these 

 two species, were seen. None being taken, their identity is uncertain.

Mr. Ball records waxwings for his vicinity, but the species is not known.

Saw only three on the whole trip; two at Little Beaver Creek and one at Buford.

One taken at Buford. I think I saw others of this species, but did not collect 

 them and identification is not positive.
