MR. SOUTHWELL ON ADDITIONS TO THE NORWICH CASTLE-MUSEUM. 47 
It will be seen that several of these eggs are interesting for 
locality’s sake, besides being new to the collection, which is rather 
deficient in this branch, indeed, until the last fifteen or twenty 
years, authenticated eggs of Birds of Prey, not European, were 
unobtainable. 
The New World Owls are now divided by trinorualists into 
several geographical races, and as this is done by recognised 
authorities, each race requires representation in a complete collection 
of the Strigidce. Mr. C. K. Worthen, the well-known dealer, who 
has had my order on hand some time, has now obtained from his 
collectors three more of these sub-species, if not four. 
I. Bubo virginianus pallescens, Stone, ? , Riverside, Colorado, 
October 21st, 18117. This is a smaller race of the well-known 
B. virginianus , and paler. 
II. Megascops asio macfarlanei, Brewst, ?, Logan, Oregon, 
December 4th, 1898. A form characterised as being of the size 
of M. kennicotti, but with the colour of M. bendirei. 
III. Megascops asio aikeni, Brewst., ?, Rocky Ford, Colorado, 
March 16th, 1898. Size of M. bendirei , with ground colour more 
ashy. Cooke says of it in his ‘ Birds of Colorado,’ on the authority 
of Mr. Hasbrouck, that it does not go north of Douglas country, 
and is not found below 5,000 feet. 
Speotgfo ( pholeoptynx ) cunicularia obscura , Steph., $* , Sacra- 
mento, California. The characters of 5. c. obscura are not 
sufficiently well founded to give it a place in the A. 0. U. 
check-list (‘The Auk,’ 1899, p. 131), but the other three species 
are admitted, and, no doubt, stand on a somewhat better basis. 
Seven sorts of Owls’ eggs were also received in the Field 
collection as follows : — 
Two Scops bakhauuena. Akyab, April 7th, 1SS3. 
One „ japonicus. Oudh. 
Three „ sunia. Neilgherries. 
Two Speotyto cunicularia. Chili. 
Three Urrua bengalensis. 
Two Bubo virginianus. 
One Ascalaphia coromanda. Delhi. 
One „ „ N. W. Provinces.” 
Among the few additions to the collection of Foreign Birds is 
a specimen of the Spotted Tinamou (Noth ura maculosa), kindly
