pale yellow. They are very large in Limioolx, except Scolopax, and 

 are occasionally absent in S. mticola, Larute, Colymbidx and Tuhi- 

 marwt, vesting sabcutaneously on the frontals between the eyes, or 

 above the orbital margin and producing on these bones deep 

 depressions, the configuration of which, together with lateral notches, 

 or canals between the nasals, lacrymals and frontals can, with care, 

 be used for taxonomic purposes. In most Anseres the glands are 

 small and placed on the upper orbital margin When they are 

 small they extend to the orbital cavity only or are restricted to the 

 maxillary cavity, as in Raittaz. Gallin&, Cdumbae, Otis, Sula, Pdargi,

NASUT.E, Nitzsch's name in 1840 for the group which Uliger 

 had called TUBINARES in 1811. 



NATATORES, Dliger's name in 1811 for an Order of Birds 

 (including 6 Families and 22 genera), equivalent to the Linnaean 

 ANSERES. Holding its place, to the exclusion of the older term, for 

 about fifty years, ornithologists at last perceived that the group 

 contained many forms which have no affinity, and the word is now 

 hardly used but by writers who know little of the principle of 

 Taxonomy. 



NATIVE-COMPANION, Grus australasianus (CRANE) ; -HEX, 

 any species of Tribonyx (RAIL) ; -PHEASANT, Lipoa ocellaia (MEGA- 

 PODE); -SPARROW, Zonasginthus octdeus, one of the WEAVER-

 Otis austrtdis, a BUSTARD all names used, according to Gould, by the 

 English in Australia or Tasmania. 



XECK, or cervix, that part of the body which extends from the 

 head to the thorax, the last cervical vertebra being the one which 

 carries a pair of ribs that do not join the STERNUM. 



NEOPHRON, the generic term given to the Vultur percnopterus 

 of Linnaeus by Savigny l when separating it 

 from the other VULTURES, and sometimes 

 used as an English word. 



XEOSSOPTTLE, see FEATHERS (p. 243). 



NERVOUS SYSTEM. This consists of 

 two parts, (1) a Central portion, composed of 



the Spinal Cord and BRAIN, and (2) Peripheral, containing the 

 Cranial and Spinal Nerves, together with all that pertains to what 

 is called the Sympathetic. 



1 He took the word from the pseudomythological Metamorphoses (or Trans- 

 formationum congeries, Fab. 5) of Antoninus Liberalis, a writer who flourished 

 about the middle of the second century, Xeophron being the name of a man 

 changed, for a base trick he played, into a Vulture by Zeus.
