Order PR0CELLARIIF0BME8 
Family PROCELLARIIDuE. 
No. 108. 
PRION VITTATUS GOULDI. 
AUSTRALIAN BROAD-BILLED PRION. 
Prion vittatus gouldi, subsp. n. ; Type no. 12373 in my collection ; Bass Strait. 
Distribution. Australian seas. 
Adult. Differs from P. vittatus vittatus (Gmelin) in its smaller bill : culmen (exp.) 
31.5 mm. ; by greatest breadth 17 mm. ; wing 187 mm. 
I CONCLUDE that this must be the bird referred to by Gould as P. vittatus 
when he described his P. 7nagnirostris. 
From St. Paul’s in the Indian Ocean I have examined specimens agreeing 
very closely with this, the bill being slightly shorter and wider. I propose for 
these the name 
Prion vittatus 7nacgillivrayi, subsp. n. 
It is interesting to note that Gould refers to P. vittatus thus : “I observed 
it on my outward passage to Tasmania near the islands of Amsterdam and 
St. Paul ; ” and added, “ the seas washing the coasts of Tasmania, New Zealand 
and the Auckland Islands are the localities whence most of the specimens in our 
Museums are obtained.” 
Apparently nothing has yet been made known regarding the habits of 
this bird.
