. Edinburgh journal of natural history and of the physical sciences . In the Rasores, Fig. I, the (Esophagus is narrow, with a very largo globular crop, having a small aperture; the proventriculus is bulbiform, with oblong, generally sac- culated glandules; the stomach is a powerful gizzard, with very thick lateral mus- cles, a prominent distinct inferior muscle, and thick rugous epithelium, or inner coat; the intestine of moderate length, and nearly uniform diameter, but having apLiended two coBca of extreme size, being together of equal capacity with the intestine. In the Gemitores, Fig. 2, the cesophagus dilates immediately with an extremely large transverse crop, internally reticularly rugous in the breeding season, and hav- ing a small aperture ; the proventriculus is bulbiform, with oblong simple glandules ; the stomach a powerful gizzard, with very thick lateral muscles; a prominent dis- tinct inferior muscle, and thick rugous epithelium; the intestine is long and narrow; the cceca reduced to very small cylindrical adnate tubes. In the Deglubitores, Fig. 3, the cesophagus gradually dilates into a membraneous sac of moderate size, lying on the right side, and sometimes curving round the back of the neck ; the proventriculus is oblong, with cylindrical glandules; the stomach a powerful gizzard, wuth very thick lateral muscles, a prominent inferior muscle, and thick rugous epithelium; the intestine short and i-ather wide; the co3ca minute, ob- long, adnate. In the Vagatores, Fig. 4, the cesophagus is rather wide, without crop or dilata- tion ; the proventriculus bulbiform, with oblong or cylindrical glandules; the stomach rather large, roundish, more or less compressed, its muscular coat of moderate thick- ness, not separated into distinct muscles, but composed of uniform fasciculi, inserted into circular tendinous spaces; the epithelium thin, and slightly rugous; the intes- tine of moderate length and diameter; the cceca very small, cylindrical, and adnate.
