LIPEURUS BACULUS Nitzsch. 



NiTZSCH, Germar's Mag. Ent., iii, p. 293, 1818. — Kellogg, List of Mallo- 

 phaga, p. 63, 1899. 



One male from Anous stolidus from Clipperton Island, and one fe- 

 male each from Geospiza fullginosa from Albemarle, from JVeso- 

 tnimus melanotis from Wenman, and from Camarhynchus productus 

 from Albemarle. This i^emarkable distribution of this characteristic 

 Lipeurus of the doves is not to be explained by straggling after death 

 of host. The Clipperton Island specimen was taken in November, 

 1898, a month or more before the collectors reached the Galapagos 

 Islands. Only terns or other maritime birds were taken on this little 

 coral island. There is no dove resident on Clipperton Island. The 

 dove Nesopelia peculiar to the Galapagos was found to be abundant 

 on Albemarle and other of the larger islands. The only parasite taken 

 from it however is Nirtmis ctirvilineatus (see p. 490). Lipeurus 

 baculus has been believed to be peculiar to doves, having been recorded 

 from a dozen or more species. Piaget records finding females 

 ^^ eg'arees" on a Sula alba^ a Totanus glottis and a Charadrius 

 minor. Our specimens from Anous and Geospiza are typical baculus., 

 differing in no specific way fi-om specimens found on the common 

 domestic pigeon in the United States and agreeing entirely with the 

 descriptions of this species by European authors.
