The iliac portion of the caud-ilio-femoralis; A B X and B X Y are less common; A X and X Y are rare and occur only in smaller groups, as in subfamilies or genera; B X occurs only in Podiceps.
But there are several subfamilies of ants whose females have the lancets of the sting useless for piercing, although the poison-glands are functional, their secretion being ejected by the insect, when occasion may arise, from the greatly enlarged reservoir, the reduced sting acting as a squirt.
The Bovidae are divided into a number of sections, or subfamilies, each of which is briefly noticed in the present article, while fuller mention of some of the more important representatives of these is made in other articles.
Summarily expressed, Garrod's scheme was to divide the parrots into two families, Palaeornithidae and Psittacidae, assigning to the former three subfamilies, Palaeornithinae, Cacatuinae and Stringopinae, and to the latter four, Arinae, Pyrrhurinae, Platycercinae and Chrysotinae.
About 80 genera with more than 500 species are recognized, divided into the family Psittacidae with the subfamilies Stringopinae, Psittacinae and Cacatuinae, and the family Trichoglossidae with the subfamilies Cyclopsittacinae, Loriinae and Nestorinae.
Giesbrecht, displacing the older name Ascomyzontidae, assigns to this family 21 genera in five subfamilies, and suggests that the long-known but still puzzling Nicothoe from the gills of the lobster might be placed in an additional subfamily, or be made the representative of a closely related family.
Placed by most systematists in the family Scolopacidae, the birds commonly called Sandpipers seem to form three sections, which have been often regarded as Subfamilies - Totaninae, Tringinae and Phalaropodinae, the last indeed in some classifications taking the higher rank of a Family - Phalaropodidae.
Mille, a thousand, in allusion to its fertility), a name applied with little definiteness to a considerable number of often very variable species of cereals, belonging to distinct genera and even subfamilies of Gramineae.
The characteristic triliteral roots of all the Semitic languages seemed to separate them widely from others; but certain traits have caused the Egyptian, Berber and Cushite groups to be classed together as three subfamilies of a Hamitic group, remotely related to the Semitic. The biliteral character of Coptic, and the biliteralism which was believed to exist in Egyptian, led philologists to suspect that Egyptian might be a surviving witness to that far-off stage of the Semitic languages when triliteral roots had not yet been formed from presumed original biliterals; Sethes investigations, however, prove that the Coptic biliterals are themselves derived from Old Egyptian triliterals, and that the triliteral roots enormously preponderated in Egyptian of the earliest known form; that view is, therefore, no longer tenable.
The family Laridae is composed of two chief groups, Larinae and Sterninae - the gulls and the terns, though two other subfamilies are frequently counted, the skuas (Stercorariinae), and that formed by the single genus Rhynchops, the skimmers; but there seems no strong reason why the former should not be referred to the Larinae and the latter to the Sterninae.
Although the lungs are present in such forms as preserve the gills throughout life, it is highly remarkable that quite a number of abranchiate salamanders, belonging mostly to the subfamilies Desmognathinae and Plethodontinae, are devoid of lungs and breathe entirely by the skin and by the bucco-pharyngeal mucose membrane (20).
