ANOPLURA (SIPHUNCULATA & MALLOPHAGa) FROM JUAN FERNANDEZ HOSTS 64 1 



I am now proposing to sink Harrison's species as a synonym of PlAGETs 

 A. bifasciatus which incidentally was obtained from Sphcniscus magellanicus 

 Forst. and not S. demersiis as stated by Harrison (1916). After comparing 

 a specimen determined as A. strulheus Harrison by its author with some of 

 PiAGETs' original specimens I can find no apparent differences. 



6. Columbicola coliinibae (Linn.). 



Pediculus columbae Linn., 1758, Syst. Nat., p. 614. Columbicola columbae {\J\nw.), 

 Ewing, 1929, A Manual of External Parasites, pp. 116, 190 — 191. 



Numerous males and females from Coliimba livia var., Masatierra. 

 This parasite seems to be a universal parasite of domestic and closely 

 allied species of pigeons. 



[Pectinopygus (Epipelicanus) sp. 



A single female, somewhat damaged, from Pelecamts occidentalis thagus 

 Molina, Chile, 11. IX. 1917.] 



7. Perineus obscuriis (Rudow). 



Lipetirus obscurus Rudow, 1869, Beitrag zur Kenntnis der Mallophagen oder 

 Pelzfresser, Diss., Halle, p. 13. Perineus obscurus (Rudow), Thompson, 1936, Ann. 

 Mag. nat. Hist., Ser. 10, XVIII, p. 42. 



A few specimens of what I take to be this species are present in the 

 collection without host data. They may have come from a specimen of Dio- 

 jHi'dea melandphrys Boie collected at Masatierra. My determination may be 

 open to doubt. 



8. Naubates pterodronii Bedford. 



Naubates pterodromi Bedford, 1930, i6th Rept. Vet. Res., S. Afr., p. 170, 

 f. 10, 13. 



Several specimens from Ptcrodrouta externa Salvin, Masatierra, 26. L 1917. 



Bedford's original description was based on specimens taken from Ptcro- 

 drouia macroptera Gm. The specimens here recorded agree so well with Bed- 

 ford's description and figures that in the absence of actual specirhens for 

 comparison I have no hesitation in stating that they represent his species. 



9. Ilalipeuriis sp. n. 



A single damaged male from Pterodroma externa Salvin, Masatierra, 26. L 

 1 917, of what is quite definitely a new species of Halipeuriis. It is a very 

 large species but in the absence of further specimen? in better condition it 

 must remain for the present undescribed.
