New Granada, i. e. the forests bordering the Magdalena river and its confluents and the northern littoral of the republic. Of the Cracidee of this district we have, probably, yet more to learn; but it is certainly rich in this as in other forms of tropical forest-life. The only Crax we have yet seen from the interior is Crax alberti. Bogota collections also occasionally contain specimens of Stegnolaema montagnii, Penelope cristata, and P. argyrotis, Pipile cumanensis, Aburria carunculata, Chamcepetes goudoti, and Ortalida guttata. Penelope greeyi and Ortalida garrula are, as far as we know, restricted to the lower portion of the valley of the Magdalena*. 3. Forest-region of Western Ecuador. From Western Ecuador we as yet know of only two species of Cracida-Chamcepetes goudoti and Ortalida erythroptera. It is quite evident that more remain to be discovered. 4. Northern littoral forests of Venezuela, Trinidad, and Tobago. Crax daubentoni appears to represent its genus in the littoral wood-region of Venezuela, whence we have also seen specimens of three other species of Cracidee, viz. Penelope argyrotis, Pipile cumanensis, and Ortalida ruficauda. Pipile cumanensis also occurs in Trinidad ; and as Ortalida ruficauda is found in Tobago, it doubtless also inhabits the intervening island. 5. Guiana. Guiana and the adjacent portion of the Amazonian basin as far as the Rio Negro is prolific in Cracidee. The Crax is C. alector. Nothocrax urumutum is found on the islands of the Rio Negro. The two species of Mitua are both recorded by Schomburgk as found in British Guiana; and Natterer obtained M. tomentosa on the Rio Brancho. Pauxi galeata is a denizen of the forests of the Rio Casiquiari and Upper Orinoco. Penelope marail is the only species of the genus Penelope of the occurrence of which in this district we have certain evidence; and Ortalida motmot is likewise the single representative of its kind in this part of the world. Pipile cumanensis is also found in British Guiana. 6. Lower Amazonia up to Rio Madeira. The mysterious Crax pinima is the only representative of its genus hitherto recorded from near Para. Mitua tuberosa was found by Natterer in the same district. Penelope pileata is the only Lower- Amazonian species of Penelope of which we can speak with certainty. Pipile cujubi and Ortalida araucuan in like manner are the sole representatives of their respective genera in this district. Altogether there are certainly five species of Cracida inhabiting Lower Amazonia, and one (P. jacupeba) is uncertain. 7. Upper Amazonia, embracing the eastern slopes of New Granada, Ecuador, Peru, and Bolivia. In Upper Amazonia the recorded number of Cracidee is larger, embracing no less than eight species. Crax globulosa is the Crax _ * To these must be now added Pauxi galeata (vide antei, p. 520) and Ortalida ruficrissa (vide antea, p. 538). |
