The inside of the mouth of this species is bright orange- 
yellow. 
100. Hypolais opaca^ Licht. The Western Pallid Warbler. 
" This Warbler is nearly the same in size as H. polyglotta, 
but is somewhat larger, and is identical with that bird in 
habits, times of arrival and departure, and also in manner of 
nesting. They build on trees, bushes, and small plants, 
laying in May or the beginning of June." — Favier. 
The above was under the head of H. elaica ; but as that bird 
does not occur and all Favier's specimens belong to H. opaca, 
there can be no doubt that the notes refer to the latter species. 
This Warbler is the latest of all the spring migrants that 
arrive in Andalucia, being a little later than H. polyglotta. 
It is much more plentiful eastward of Gibraltar than in the 
immediate vicinity, where it is rare. Another species, //. oli- 
vetorum, is stated to have been met with at Tangier and Fez, 
but did not come under my observation. 
101. CisTicoLA scHGENicoLA, Bp. The Fautail- Warbler. 
Moorish. Bou-fesito (Father of eloquence). Spanish. Cierra- 
puno, Tin-Tin. 
" Is the most common of the aquatic Warblers around 
Tangier, and seen migrating in lots of from ten to twelve 
during March and April, returning in October, November, 
and December. Many remain to breed, nesting twice in the 
season."^ — Favier. 
This diminutive Sedge- Warbler, as I may call it, is resi- 
dent near Gibraltar, and exceedingly plentiful, in the winter 
frequenting marshy ground wherever there is any herbage, 
such as grass, sedges, or short rushes. In the spring they go 
to the corn-fields as well, never, however, being found away 
from water. I do not recollect ever seeing them perch on a 
bush or tree, but always on some plant. Their note and 
jerky flight somewhat remind one of the Meadow-Pipit; 
during the nesting-season in particular they will fly darting 
about high over head for several minutes, continually uttering 
their squeaky single note (whence the name of Tin-Tin), all
