FicepULA HYPOLAIS YELLOW-BROWED WARBLER. : fe ‘ ata a é T An accidental visitor to England and Ireland ; common in Holland and other parts of Europe and North Africa, from which latter country it migrates north in spring, filling the dwarf woods and osier-beds of f da, ’ France and Holland with its melodious voice. Family CALAMODYTID. Ornithologists will, I am sure, agree with me in considering that the Sedge-birds constitute a very distinct family. The numerous species, which have been divided into many genera, are very generally distributed over the older-known portion of the earth’s surface. They are semiaquatic in their habits; the greater number frequent both large and small beds of sedges and other herbage growing in the vicinity of water, and feed upon insects. They are well represented in the British Islands, over which the species are generally distributed. In the present work these birds have been classed under the generic titles of Acrocephalus, Calamoherpe, Calamodyta, Lusciniopsis, and Locustella. Genus AcROCEPHALUS. The members of this genus are the largest birds of the family ; and one or other of them form part of the avifaunee of Europe, Asia, Africa, and Australia. Vol. If. Pl. LXXIL 123. AcROCEPHALUS TURDOIDES Turusu WarBLeER. Besides inhabiting the continent of Europe and the neighbouring countries, the Thrush Warbler finds its way to England, as will be seen on reference to the letterpress opposite the Plate on which the species is represented. It can only be regarded as an accidental visitor. Genus CaLaMouERPE. What has been said respecting the distribution of the members of the last genus is equally descriptive of those of the present one. Vol. If. Pl. LXXIL 124. CaLaMonERPE ARUNDINACEA : : Reep-Wars er.
