Jouanin, who described this species la 1955 (L'Qiseau, 25:160), wrote 
(pers. corr.j, 7 May 1968) " 11 s’agit d'un exampleire typique 
de Bulweria fallax ." 
Measurements of the hisianskl specimen, a male with the left testis 
measuring 5 x 3 mm., were taken from the frozen carcass prior to its 
preparation as a study skin. These were: culmen, 26.3 on., wing (chord) 
243 mm., tall 120 cm,, end tarsus, 30 mm. These measurements are simile; 
to the measurements of a male collected by Bailey (Ibis, 1966, 108:239) 
(28.5-238-113-31) and with the measurements of the male type (Jouanin, 
op.cit.)(28-232-12^-32) except for the measurement of the wing of the 
latter which is not comparable since the flight feathers were in molt. 
Differences in the measurements of the type of Bulweria mae&iilivrayi 
(25-206-85-3^.5) (Jouanin, op.cit.) except for those of the bal&en 
and possibly the tarsus, are probably not significant since growth of 
the flight feathers had not been completed.
