Feb., 1922 The Queensland Naturalist. 53 
lagotis (Reid) is found in West Australia. T. sagitta 
Thomas, known as Urgarta, is a South and Central Aus- 
tralian form. Professor Sir Baldwin Spencer described 
smaller specimens from Charlotte Waters as Peragale minor, 
whilst Peragale leucuta Thomas, whose actual habitat is 
unknown, is thought to have been collected in Central or 
North-Central Australia. The generic term Peragale , Gray, 
is antedated by Owen’s Thalacomys . Until a detailed 
examination is made of the skull of our specimen, it would 
be unwise to define its specific position, but it is closely 
related to Spencer’s T. minor. Specimens from Surat and 
from Cunnamulla have been previously recorded in the 
Queensland Museum registers. 
A study of a skull shows a big development of the 
olfactory fossa, or fore part of the cerebral chamber con- 
taining the olfactory lobes of the brain, from which nerve- 
branches pass out to the nose through surprisingly large 
openings in the cribriform plate. 
ORCHIDS OF A SUBTROPICAL HIGHLAND. 
By (Miss) Hilda Geissmann, Tambourine Mountain. 
[The author of this article is one of our country members, 
resident at Tambourine Mountain, and a close student of the wild- 
flower flora of that botanically very rich locality. Queensland 
possesses about 160 species of named Orchids, and of these about 100 
are epiphytic species and about 60 terrestrial ones. This State does 
not possess the wealth of ground orchids characteristic of the Southern 
States, but, on the other hand, with the exception of one or two 
species in the Northern Territory and a few in New South Wales, 
practically all the Australian species of epiphytic ones (those that 
grow on trees and rocks) are found in Queensland. Miss Geissmann 
lists twenty-one epiphytic sorts and ten terrestrial ones, a total of 
thirty-one species. (For the most part, the vernacular names are her 
own, and quite appropriate). In addition, there are four species of 
which she has not yet been able to ascertain the botanical names, and 
these are not included in the present list. — E ds.] 
ARBOREAL OR ROCK ORCHIDS. 
Rock Lily ( Dendrobium speciosum). — Large stiff 
plants, found on trees and rocks. Long sprays of creamy 
dowers. Blooms in September. 
Shell Pink Orchid (Dendrobium Kingianum ). — 
Found on the ground between rocks around open waterfalls 
•and on creek banks. Has sprays of delicate pink flowers. 
Curious habit of propagation — forms new plant at the end 
of stems, which drops off when strong enough and grows 
by itself. Flowers in September.
