Show 146 MR. FORBES ON THE STOMACH IN TANAGERS. [Mar. 2, developed than in the more slender-billed gener&Tanagra, Calliste, &c. W h y the genera Euphonia and Chlorophonia alone, as far as it is yet known, of birds should present this structure is an as yet unsolved problem ; I believe they differ in no appreciable degree from other Tanagers in food*• or habits. I may also remark that in such genera as Ccereba and AEthopyga, feeding chiefly on minute insects and juices of flowers, there is a well-marked gizzard, with muscular walls and hardened epithelium. Subjoined is a list of all those species of Tanagers, 27 in number belonging to 11 genera, in which the condition of the stomach is as yet known. This includes the species mentioned by Lund (L.), as well as those examined by the late Prof. Garrod (A. H. G.) and myself, and the nomenclature is that of the ' Nomenclator,' Mr. Sclater having kindly reduced Lund's names to the terms of that list for me. Tanagers with the stomach abnormal. Chlorophonia viridis (W. A. F.). Euphonia chlorotica (L.). trinitatis (W. A. F.). violacea (L., A. H. G., & W. A. F.). rufiventris (L.). pectoralis CW. A. F.). Tanagers with a normal stomach. Calliste tricolor (L. & W . A. F.). festiva (L. & A. H. G.). cyaneiventris (L.). thoracica (L.). melanonota (L.). nigriviridis ( W . A. F.). Tanagra episcopus (hi). ornata (L.). abbas (W. A. F.). sayaca(W.A.F.&A.ILiG.). palmarum (L. & A. H. G.). Rhamphoccelus brasilius (L.). - jacapa (W. A. F.). Pyranga erythromelcena (W. A. F.). Trichothraupis quadricolor (L.). Tachyphonus mela leucus (W. A. F.). cristatus (L.). coronatus (L.). Saltator magnus (L.). Cissopis leveriana (W. A. F.). Pitylus fuliginosus CW. A. F.). Two other species not named by Lund. Pipridea melanonota is mentioned by Lund (under the name Tanagra vittata) as one of the species with a normal stomach. On the other hand, according to M . Taczanowski (P. Z. S. 1879, p. 226), Stolzmann found in this bird "la poche stomacale rudimentaire," 1 Several of the wild specimens of Euphonia that I have dissected have had in their intestines a large number of small round reddish seeds, which are probably, M r. Salvin tells me, those of a climbing species of Ficus common in the Central-American forests. - |
