758 QUAKER—QUEZAL 
larger one is seldom if ever seen. Both appear to be equally 
courageous, and their thoroughly Falconine aspect is shewn by the 
annexed figure. 
QUAKER, a sailors’ name for the Dusky Albatros, Phebetria 
Fuliginosa. 
QUAKETAIL, a book-name invented for the Yellow WaAGTAIL 
and its allies, after they had been generically separated from 
Motacilla as Budytes. 
QUAM or QUAN, old ways of spelling what is now written 
GUAN. 
QUA-QUA, the Creole name in Tobago, for a species of 
Thamnophilus (ANT-THRUSH, p. 21) there found. 
QUEEST or QUIST, an abbreviated corruption of CuSsHAT. 
QUESAL or QUEZAL the Spanish-American name for one of 
the most beautiful of birds, abbreviated from the Aztec or Maya 
Quetzal-tototl, the last part of the compound word meaning fowl, and 
the first, also written Cuetzal, the long feathers of rich green with 
which it is adorned.! The Quezal is one of the TROGONS, and was 
originally described by Hernandez (Historia, p. 13), whose account 
was faithfully copied by Willughby. Yet the bird remained 
practically unknown to ornithologists until figured in 1825, from a 
specimen belonging to Leadbeater,? by Temminck (Pl. col. 372) 
who, however, mistakenly thought it was the same as the T'rogon 
pavoninus, a congeneric but quite distinct species from Brazil, that 
had just been described by Spix (Av. Bras. i. p. 47, pl. xxxv.) In 
1832 the Registro Trimestre, a literary and scientific journal printed 
at Mexico, of which few copies can exist in Europe, contained a com- 
munication (pp. 43-49) by Dr. Pablo de la Llave, describing this 
1 Dr. Tylor informs me that the Mexican deity Quetzal-coat] had his name, 
generally translated ‘‘ Feathered Snake,” from the quetzal, feather or bird, and 
coatl, snake, as also certain kings or chiefs, and many places, e.g. Quetzalapan, 
Quetzaltepec, and Quezaltenango, though perhaps some of the last were named 
directly from the personages (cf. Bancroft, Native Races of the Pacific States, 
vol. v. Index). Quetzal-itzli is said to be the emerald. 
2 This specimen had been given to Mr. Canning (a tribute, perhaps, to the 
statesman who afterwards boasted that he had ‘‘called a New World into 
existence to redress the balance of the Old”) by Mr. Schenley, a diplomatist, 
and was then thought to be unique in Europe; but, apart from those which 
had reached Spain, where they lay neglected and undescribed, James Wilson 
says (Lllustr. Zool. pl. vi. text) that others were brought with it, and that one 
of them was given to the Edinburgh Museum. On the 21st day of the sale of 
Bullock’s Museum in 1819, Lot 88 is entered in the Catalogue as ‘The Tail 
Feather of a magnificent undescribed Trogon,” and very likely belonged to this 
species. It was bought for nineteen shillings by Warwick, a well-known 
London dealer.
