66 DENDROCOLAPTIDJE. 



Although d'Orhigny collected at Valparaiso specimens of the true 

 S. JiHinicola, the species figured under that name in his work is 

 clearly distinct, as was first pointed out by lleichenbach. 



I have compared one of d'Orbigny's skins of tliis species in the 

 Paris Museum (collected at Cochabamba in 1834, and marked "■ S, 

 humicola ") with a specimen in my own collection obtained near Men- 

 doza by Wcisshaupt. I therefore do not doubt that I am correct in 

 referring Landbeck's S. crassirostris (established on examples from 

 the same locality) to this species.

Distinguishable from 8. orhignii by the want of the basal rufous 

 baud on the secondaries and by its larger size.
