198 ANATIDiE. 
arriving during September and October, leaving for the north 
in February and March." — Favier. 
The Shoveller is met with in considerable numbers on the 
Spanish side of the Straits. They mostly arrive around 
Casa Vieja and on the Laguna de Janda in October ; and I 
have known of their occurrence there in August, but have no 
certain knowledge of their nesting in the neighbourhood ; 
indeed I never saw any later than the end of April. 
This (the only species of the genus to be found in Europe), 
owing to the shape of the bill, which is dilated broadly at the 
end, cannot be well mistaken for any other Duck. The alar 
speculum is metallic green. 
275. Chaulelasmus streperus (Linn.). The Gadwall. 
" This species is as scarce near Tangier as Fuligula rufina, 
the Red-Crested Pochard ; and their appearance, which takes 
place between February and March, is irregular and un- 
certain.'^ — Favier. 
The Gadwall, on the Spanish side of the Straits, cannot be 
termed a common bird. I only met with it on a few occa- 
sions : one shot at flight on the 26th of November 1869, 
another shot at flight on the 22nd of December 1871 at 
Tapatanilla, and three others killed there in February 1874, 
are my only personal experiences of it ; but I have seen it 
in Seville market in February and March. 
Lord Lilford informed me that he saw ten or twelve 
Gradwall at the lakes of Sunta Olaya, in the Goto de Donana, 
in the early part of May, and considered that they were 
breeding, although he was unable to discover a nest. He 
also informed me that the local name there was " Frisa " — a 
word which signifies coarse cloth or frieze. 
This Duck, with its plain plumage, can be easily distin- 
guished by the colourless or white alar speculum, the outer 
webs of the secondaries being white. The male has the 
point of the wing and the small coverts bright chestnut ; the 
legs are a dirty yelloAv. 
The total length is from 19 to 21 inches.
