[On a further Occurrence of the Australian Tree-Swallow (Hylochelidon 
nigricans) in New Zealand. By Walter L. Buller. Trans. N.-Zealand 
Inst. xi. p. 360. | 
Dr. Buller records the occurrence of a “ Martin” in New 
Zealand near Blenheim, as observed by Mr. J. R. W. Cook. 
This was probably Hylochelidon nigricans of Australia, which

These numbers of the ‘ Bulletin’ contain many papers and 
notes of interest to American ornithologists. Mr. Ridgway 
(1879, p. 218) describes a new American Peucea (P. illino- 
ensis) from “ the semi-prairie districts, extending from South- 
ern Illinois to Central Texas,” formerly referred to P. esti- 
valis. Mr. Ridgway, however, subsequently (1880, p. 52) 
degraded the form into a subspecies, as “‘ P. estivalis illino- 
ensis.”’ It appears, from the same gentleman’s examination, 
that “ Helminthophaga gunnii, Gibbs,” a supposed new species,
