MR. FORBES ON THE STOMACH IN TANAGERS. [Mar. 2, 



developed than in tte more slender-billed genera rawa^ro, Calliste, &c. 

 Why the genera Euiihonia 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 Mthopyga, 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.). 



rujiventris (L.). 



pectoralis (W. 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 (L.). 



ornata (L.). 



abbas (W. A. F.). 



5«yaca(W.A.F.&A.H.G.). 



pahnarum (L. &A. H. G.). 



Rhamphocoelus brasilius (L.). 



jacapa (W. A. F.). 



Pyranga erythromelcena (W. A. F.), 

 Trichothraupis quadricolor (L.). 

 Tachyphonusmelaleucus(W . A. F.). 



cristatus (L.). 



coronatus (L.). 



Saltator magnus (L.). 

 Cissopis leveriana (W. A. F.). 

 Pitylus fuliginosiis (W. A. F.). 



Two other species not named 

 by Lund. 



Pipridea melanonota is mentioned by Limd (under the name Tana- 

 gra 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," 



^ 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, Mr. Salvin teUs me, those of a climbing species of Ficus common in 

 the Central- American forests.
