ANOPLURA (SIPHUNCULATA & MALLOPHAGA) FROM JUAN FERNANDEZ HOSTS 641 
I am now proposing to sink HARRISON's species as a synonym of PIAGET's 
A. bifasciatus which incidentally was obtained from Spheniseus magellanicus 
Forst. and not S. demersus as stated by HARRISON (1916). After comparing 
a specimen determined as 4. strutheus Harrison by its author with some of 
PIAGETS’ original specimens I can find no apparent differences. 
6. Columbicola columbae (Linn.). 
LPediculus columbae Vinn., 1758, Syst. Nat., p. 614. Columbicola columbae (Linn.), 
Ewing, 1929, A Manual of External Parasites, pp. 116, 190—191. 
Numerous males and females from Columba 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 Pelecanus occidentalis thagus 
Molina, Chile, 11. 1X. 1917.} 
7. Perineus obscurus (Rudow). 
Lipeurus obscurus Rudow, 1869, Beitrag zur Kenntnis der Mallophagen oder 
Pelzfresser, Diss., Halle, p. 13. erimeus obscurus (Rudow), Thompson, 1936, Ann. 
Mareomat., Hist. Ser. ro, XVII: 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 Dvo- 
medea melanophrys Boie collected at Masatierra. My determination may be 
open to doubt. 
8. Naubates pterodromi Bedford. 
Naubates pterodromi Bedford, 1930, 16th Rept. Vet. Res., S. Aff., p. 170, 
farO, 13. 
Several specimens from Prerodroma externa Salvin, Masatierra, 26. I. 1917. 
BEDFORD’s original description was based on specimens taken from Peero- 
droma macroptera Gm. The specimens here recorded agree so well with BED- 
FORD s description and figures that in the absence of actual specimens for 
comparison I have no hesitation in stating that they represent his species. 
g. Walipeurus sp. n. 
A single damaged male from Pterodroma externa Salvin, Masatierra, 26. I. 
1917, of what is quite definitely a new species of Halipeurus. It is a very 
large species but in the absence of further specimens in better condition it 
must remain for the present undescribed.
