DEFINITIONS

LORICULUS
(Psittacidae; Ϯ Blue-crowned Hanging Parrot L. galgulus) Dim. < genus Lorius auct. (= Larius Boddaert, 1783 = Eclectus Wagler, 1832), parrot (cf. dim. < genus Lorius Vigors, 1825, lory; dim. L. lorica  breastplate; "uropygio pectoreque coccineis" (Linnaeus 1758)); "No. 1820. LORICULUS ASIATICUS; Psittacus asiaticus, Latham, and Ps. indicus, Gmelin,—both founded on Edwards, pl. 6, which is a good representation. The names, however, are bad, as the race would seem to be wholly confined to Ceylon: while L. vernalis inhabits all India, and the countries bordering the eastern shores of the Bay of Bengal, as far as the Tenasserim provinces where it abounds, and also Java; whereas in the Malayan peninsula there appears only to be L. galgulus.  L. asiaticus differs from L. vernalis in having the crown deep red, passing to a saffron hue on the nape, and in some specimens over much of the back; while the fore-part of the neck is tinged more or less deeply with verditer.  The nearest affinity of these Loricules is with the genus Eclectus; and there are other species in the Philippines and probably the south of China."
