On refering to our journals, we find the following note. "_Papilio Leilus._--Great numbers of this insect were flying during the whole of the morning, past _Aqua Fria_ (Pernambuco), in a direction from north to south: not one deviated from this course, notwithstanding the flowers which were growing around: they flew against the wind, which blew rather strong, and near the ground, but mounted over every tree or other high object which lay in their course; yet their flight was so rapid, that I could not capture a single specimen. They went singly, and near fifty or sixty must have passed the spot opposite the window, before mid-day: they continued to pass for three or four days in this manner. 12th June, 1817." Now it is clear that these insects could not have come from so far north as Surinam, where only the other species is found; and they certainly do not migrate to the more southern latitude of Rio de Janeiro. As we have never seen this species in the London Cabinets, we have deposited a specimen in the British Museum, that our entomologists may become acquainted with the structure of the feet. * * * * * * [Illustration: MALACOCIRCUS _Striatus._ _Striped Babbler._] MALACOCIRCUS striatus. _Striated Babbler._ ---- Family Merulidæ. Sub-fam. Crateropodinæ. Sw. _North. Zool. 2, p 156._ Genus Malacocircus. GENERIC CHARACTER. Bill rasorial, i. e. short, high at the base, conspicuously arched from the front, where the feathers are divided; tip obsoletely notched. Tarsi thick, moderate; the scales entire. Wings and tail rounded. SUB-GENERA. Megalurus. Pomatorhinus. _Horsf._ Malacocircus. Leptonyx. _Sw._ ---- SPECIFIC CHARACTER. _Entirely light brown: wings and tail darker, the quills marked by transverse dark lines: bill and feet yellow: margin of the quills changeable greyish white._ Gracula striata. _Mus. Paris._ ---- The Babblers, or long legged Thrushes, (forming the sub-family _Crateropodinæ_, Sw.) are almost exclusively confined to the warmer latitudes of the old world; extending to the north as far as Egypt, and to the south over the greatest part of Australia. Like all birds which belong to the natatorial type, the majority of the species live in the vicinity of water. Their voice, like that of _Donacobius_, Sw. is particularly discordant, and many of them appear to be gregarious. The present species we received from Ceylon, but without any notice of its habits: another specimen is in the Paris Museum, under the manuscript name of _Gracula striata_, from the circumstance of the scapular quills, and also the tail feathers, being marked with transverse lines of a darker brown, varying in intensity according to the rays of light.
