Not included by Dr. Leotaud, and never seen by Mr. Taylor (Ibis, 1864, p. 83). Fam. RAMPHASTID2E. 88. RAMPHASTOS ERYTHRORHYNCHUS (Gmel.) ; Burm. Thiere Bras. ii. p. 204, note. One specimen, not different from Guiana specimens. The size varies a good deal. Long. al. caud. rostr. tars. 8" 7'" 6" 0'" 6" 9'" 2" 0'" (Trinidad.) 9 0 60 68 20 (Guiana.) 8 3 5 9 5 9 1 11 (Guiana.) This species is not included by Dr. Leotaud. 89. RAMPHASTOS VITELLINUS, Licht.; Scl. Cat. p. 325 ; Leot. p. 325 ; Taylor, I. c. p. 93. One specimen, agreeing with a Guiana specimen in the Bremen collection. 90. PTEROGLOSSUS ARACARI, L.; Scl. Cat. p. 325. One specimen, similar to another from Guiana. Dr. Leotaud does not notice this species from Trinidad. The P. wiedii, Sturm, is very closely allied, and can be distinguished only by a slight difference in the markings on the upper mandible, as has been pointed out very minutely by Mr. Sturm (Monogr. Ramph. 4 Heft). P. aracari is not confined in its distribution to Guiana and Northern Brazil; for Prof. Burmeister (ii. p. 208) got the true P. aracari in Minas Geraes. The black strips along the culmen varies in extent; in our Guiana specimen it is 5|'" broad, in the Trinidad one 5|'", in the Brazil specimen (P. wiedii) 4'". The size is also variable. Long. al. caud. rostr. tars. 5" 6'" 6" 0'" 4" 6'" 16'" (Trinidad.) 5 7 5 9 4 0 17 (Guiana.) 5 10 6 0 3 9 16 (wiedi, Brazil.) Dr. Cabanis has separated a conspecies from Venezuela (P. formosus, Journ. f. Orn. 1862, p. 332), said to be different from wiedii in having the chin and throat dark red-brown, the black stripe along the culmen narrower, and in its larger size (the measurements are, unfortunately, not noticed). I doubt whether these differences, based on a single specimen, are of specific value; the dark reddish-brown tinge on the ear-coverts, on the chin and throat, is also visible in our Brazilian specimen, and, as remarked by the Prince of Wied, is peculiar to the female. |
