273. Siercorathts parasiticus. Buffon's Skua. 
An occasional visitor to the coast on migration, usually 
in the autumn. 
Mr. Hart has specimens obtained near Christchurch, on 
September 25th, 1889 ; and in October, 1891. 
During the autumn of 1891, there was a large visitation 
to this county, especially to our south-western coast, where 
it was observed, curiously enough, that most of the birds 
were adult. Two or three were caught alive, and one was 
sent to the gardens of the Zoological Society, being the 
first of its kind ever seen there.^ 
A young bird obtained at Crawley about the same 
time was identified by Dr. P. L. Sclater. 
This species is a native of the Arctic regions of both 
hemispheres. 
Order—TUBINARES. 
Family — ProcellarUdce. 
Genu S — Procellaria.

Christchurch, in November, 1870, 1 871 and 1883.
