Docophorus fuliginosus n. sp. (Plate iii, fig. 2.) 



A few specimens from a Black-bellied Plover, Chara- 

 drins squatarola (Lawrence, Kansas), and a single male 

 from a specimen of the same bird-species shot near Palo 

 Alto, California. The new species belongs to the group 

 rotimdati (with convex or truncate clypeus) of Piaget's 

 super-group latitemfiorales, which includes the Docophori 

 of the shore birds. This group closely resembles the 

 group piistnlosi of the Terns, and this species from Chara-
