In the Cockatoos, too, the orbit is completely encircled by bone 1, and, as a rule, doubly so (vide P. Z. S. 1874, pl. lxxi.). In Nasiterna, as already stated, it is not so. Of the other " Palceornithidce," as defined by Prof. Garrod, the Trichoglossince form a well-marked group, characterized by numerous features to which there is no approach in Nasiterna. Its nearest allies must therefore be in the remaining forms of that family, which I propose to call Eclectinee, including all those not either Cacatuine or Trichoglossine, with the exception, perhaps, of the ground-frequenting forms, Stringops, Pezoporus, &c. The spiny tail-feathers of Nasiterna are, no doubt, very peculiar, and with its cnrious beak and diminutive size must always make this a very well-marked genus. But I fail to see in its spiny tail sufficient importance to elevate Nasiterna into a special subfamily, as suggested by Mr. Sclater. Cheetura is not separated on similar grounds from the other Chceturince; nor has the spatulate tail of Prioniturus been advanced as entitling that genus to form a special subfamily. The anatomy of the small short-tailed genera Cyclopsitta, Psittacella, &c. is as yet unknown ; but I believe that it is amongst these forms-related, as far as can be judged from external appearance, through this last to Pezoporus, Geopsittacus, &c.-that Nasiterna has its nearest allies. Agapornis and Psittinus are also not very distantly related, though I believe that the loss of its furcula by Ayapornis, in which it resembles Nasiterna, is probably due to independent causes2. That the loss of the furcula is not exclusively correlated with terrestrial habits is shown by its absence in three such essentially arboreal genera as Agapornis, Nasiterna, and the Neotropical Psittacula. 3.

Mr. Walker in his ' Catalogue of Lepidoptera Heterocera in the British Museum,' part xxviii. p. 501, 1863, described three species of the genus Adela-A. purpurea and A. bellela from North America, and A. albicornis from Natal. The first of these (A. purpurea) has since been described by Prof. Zeller under the name of Adela 1 This was not the case, however, in a specimen of Calyptorhynchus funerens lately examined by me. ... • i , • , • 2 Judging by its behaviour in captivity, Agapornis is extremely sluggish m ils movements. |
