Specimens of this long known parasite of doves and 

 pigeons taken from a domestic pigeon, Columbci //via. I 

 follow Piaget and Taschenberg in their refusal to recog- 

 nize as species the numerous variants observed. The 

 definition of this species presents a case similar to that 

 presented by Lipeurus squalidus (see discussion of 

 squalidus). 



I figure the female and head of male, not alone for the 

 convenience of American students, but because the pre- 

 viously published figures of this species are faulty. Piaget 

 figures the male. Osborn's figure, undoubtedly well 

 drawn, is spoiled in the printing. Piaget is in error in 

 attempting to correct Giebel's statement that there are 

 four small clavate appendages on the frontal part of the 

 clypeus. Piaget declares there are but two such append- 

 ages; in my specimens there are distinctly four. The 

 female specimen figured by me measures: body, length 

 2.5 mm., width .37 mm.; head, length .42 mm., width 

 .28 mm.

 Two specimens, one immature, from a Bob-white 

 Co/inus virginiunus (Lawrence, Kansas). Piaget de- 

 scribed the species from specimens taken from the same 

 bird species in the Zoological Garden of Rotterdam. 

 My specimens differ from Piaget's description in some 

 particulars. Piaget says, " l'oeil nu;" my specimens 

 have a distinct longish hair in the eve ; the lateral bands
