Lesson, 111. Zool. Plate XVI ? 



A single specimen, which appears to be that described by Mr. Peale, 

 is in the collection of the Expedition, and is the only representative of 

 this remarkable genus. It is labelled as having been obtained in Peru, 

 and though not in mature plumage, is apparently the species described 

 by Tschudi, in Wiegmann's Archiv and in Fauna Peruana as above. 

 Tschudi mentions no other species as inhabiting Peru. We are at 

 present not without a suspicion that Thinocorus Sivainsoni, Lesson, 

 will prove to be identical with the Peruvian species now before us, 

 but have not the facilities necessary for a conclusive examination. 



Mr. Peale mentions this species thus : 



" They were obtained on high sandy plains, at the Island of San 

 Lorenzo, Peru. Their flight is rapid and dodging. On the ground, 

 they have very much the appearance of Brown Larks or Sparrows."
