On October 26th, Mr. Stronach donated a second specimen, 
also found to the north of Cottesloe. The specimen was mummified 
and had evidently been dead for some considerable time. In 
spite of its poor condition it lias been added to the reserve col- 
lection on account of its rarity. The sex of this bird could not 
be determined. 
This species has often been seen off the Australian coast, but 
prior to Mr. Stronach’s first discovery had never been actually 
captured in Australia. 
The type locality of the species is the Cape of Good Hope. 
Pachyptila vitiuta (Gmelin) — Broad Billed Prion or Dove 
Petrel. — This bird does not seem to have been at all plentiful in 
1920. No specimens arrived at the Museum and I saw very few on 
the beach. The first specimen to reach the Museum was one I 
collected north of Osborne on July 3rd, 1917, at which time only 
one specimen, then in the collection of Mr. Gregory Mathews, and 
now in t lie British Museum, was known. 
Pachyptila desolata (Gmelin) — Prion or Dove Petrel. — As 
usual large numbers of Prions were lying dead on the beach. They 
can be distinguished from the preceding by the shape of the bill 
and smaller size. 
Diomed ea ( Thalassarch e ) m elomoph rys Te ram. — Bla ck-b rowed 
Albatross.' — This albatross, which is exceedingly common off the 
south coast of Australia, is rarely met with along the west coast, 
the extreme limit being Cape Naturaliste (Ferguson). 
By the taking of a specimen at Cottesloe on August 21st its 
range is considerably extended. 
The type locality of the species is the Cape of Good Hope. 
Diomedea (Thalassogeron) chrysostoma Forster. Grey-headed 
Albatross. — A specimen of this Albatross or Molly hawk was a 
welcome addition to the collection, though not of particular inter- 
est, as a living bird had been captured by Mr. Stronach at Cottesloe 
in 1917. 
Diomedea (Thalassarche) chlororhynchu ,s Gmelin — Yellow- 
nosed Albatross — Two decomposed specimens were seen on the 
beach south of Cottesloe on August 21st.
