Mallophaga from Bolivian Birds. 



By V. L. KELLOGG and J. H. PAIXE, Stanford University, 



California. 



The following" determinations and descriptions of new spe-

 from Bolivian birds in 1901 by the late Perry O. Simons. 

 (This unfortunate collector of birds for the British Museum 

 was murdered by Indians in the Bolivian mountains in 1902

Docophorus laticeps Giebel. 



Several specimens from the "white-headed oriole" (Choro, 

 Bolivia, 3500 metres, dry season). 



Docophorus communis Nitzsch. 

 Specimens from "bird" (Choro, Bolivia). 



Docophorus fissi-signatus n. sp. (Fig. 1.) 



Two females from "desert curlew" (Lagonillas, Bolivia). 

 This species belongs to Piaget's type fisignati from the Spoon 



bills and Ibises and is the second of this type that we have 



found on curlews in this country.
