No. A. 106.—Purrinus TRISTIS, Forst. 
Mutton-bird. 
The young mutton-bird has been obtained from holes in the cliff at 
Sumner ; this downy mass of oil presents the curious fact of being larger than 
the parent bird. 
No. A. 119.—PRIoN AUSTRALIS, N. 8. 
Southern Prion. 
A short time since amongst some birds which arrived at the Canterbury 
Museum from Foveaux Strait, transmitted by the Rev. T. Wohlers, were 
specimens of a Prion which, from a careful inspection, could not be referred to 
either P. turtur or P. vittatus. 
It is said to breed in holes, and descriptions are given below of the adult, 
young, and egg. In considering this specimen as new it is to be noted that 
the bill is considerably longer than the head ; it is also much broader than 
that of P. vittatus, according to Gould. The pectinated apparatus of the 
upper mandible is fully disclosed. Of the primaries the first is quite as long, 
if not longer than the second quill, whilst the total length exceeds that of 
P. vittatus by some inches. It breeds on Papatea, or Green Island, near 
Ruapuke, in Foveaux Strait. 
Adult—Head dark bluish grey, mottled sparingly with black; aurals 
slatish, bounded above and below irregularly with white or yellowish white ; 
upper surface bluish grey ; scapulars clouded with slaty black, tail-coverts 
tipped with the same ; under surface white; under tail-coverts white, just 
tinged with delicate ash grey; guill feathers, of which the two first are 
longest and of about equal length, outer web black, inner web white, more or 
less stained with ash grey; tail bluish grey tipped with black ; chin naked, 
the skin marked with narrow angular furrows arranged in regular order, angle 
within angle ; bill longer than the head.

The young om out of a nest by ‘Mr. Wohlers on the 25th November 
are clothed entirely witha dense covering of dark smoky grey, lightest on the 
neck and under surface, pectinations of the upper mandible undeveloped ; the 
bill measures from gape to point 1 inch, greatest width only 4 lines. The
