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.
Finsch published at Leiden an elaborate monograph of the parrots, 4 regarding them as a family, in which he admitted 26 genera, forming 5 subfamilies: (I) that composed of Strigops (Kakapo), only; (2) that containing the crested forms or cockatoos; (3) one which he named Sittacinae, comprising all the long-tailed species - a somewhat heterogeneous assemblage, made up of Macaws and what are commonly known as parakeets; (4) the parrots proper with short tails; and (5) the so-called "brush-tongued" parrots, consisting of the LoRIES (q.v.) and Nestors.
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.
