DEFINITIONS

DRYOTRIORCHIS
(Accipitridae; Ϯ Congo Serpent Eagle D. spectabilis) Gr. δρυς drus, δρυος druos  tree; τριορχης triorkhēs  hawk, buzzard  < τρεις treis, τρια tria  three; ορχις orkhis  testicle (see Triorchis); "I RECEIVED in one of my last consignments from the interior of Fantee an adult specimen of the Astur spectabilis of Schlegel, which seems to indicate to me that we have hitherto been mistaken in referring this bird to the Goshawks, and that it is in fact an Aquiline form, with tarsi reticulated both before and behind.  Mr. Sharpe has examined the bird with me, and agrees that it cannot be placed in any existing genus. I therefore propose to make a new one for its reception as follows: — DRYOTRIORCHIS, gen. nov.*  Type D. spectabilis (Schl.); Astur spectabilis, Schl. Ned. Tijdschr. Dierk. i. p. 13, pl. 6.  This new genus is allied to Circaëtus, from which it differs in its short wing and long tail. The latter is nearly as long as the wing itself, the difference between them being less than the length of the tarsus. It differs from Herpetotheres, in which Prof. Schlegel was inclined to place it, in its oval nostrils, and from Spilornis in its lanceolate crest as well as the proportions of the wing and tail.  ...  *δρυς, quercus, et τριορχης, accipiter." (Shelley 1874); "Dryotriorchis Shelley, Ibis, 1874, p. 90.  Type by original designation, Astur spectabilis Schleg." (W. Sclater, 1924, Syst. Av. Aethiop., I, p. 62).
