Mention should be made of the very interesting col- 
lection of birds and animals at the Kiosk at Mt. Coot-tha, 
most of which can be inspected at close quarters' by visit- 
ors, who are admitted to most of the cages. One won- 
ders, however, how these birds and animals will fare dur- 
ing the hot summer months, shut up in an enclosure con- 
structed with the idea of keeping outsiders from viewing 
the contents rather than the convenience or health of the 
inmates. The Club should keep an eye on this possible 
defect. 
A NEW SPECIES OF THE GENUS 
PTEROSTYLIS, R.Br. 
By W. H. NICHOLLS. 
PTEROSTYLIS HILDAE, sp. Nov. 
Plant a glabra, gracillima, circa 10-15 cm., alta, Folia 
ad basem, 2-3 ovata vel oblonga, longinuscule petiolata; 
caulina bract eat a parva, 2-4. 
Flos solitarius, viridis, parvus; galea erect a, incurva, 
sub -acuta; labium inferius, erectum, cuneatum, apice 
subulatum ; labellum elliptico-oblongum, irritabile 
mobile-unguiculatum, fere strictum, apice obtusum; 
lamina circa 9-11 mm. longa, in medio linea, elevata, 
longitudinaliter ; basi appendix linearis, penicillata. 
Columna erect a, circiter 12-15 mm. longa, lobo 
superiore subulato; lobo inferiore anguste oblusta; mar - 
grnibus introrsis ciliatis; stigma angustum, prominens. 
A slender glabrous species about 10-15 cm. high, 
leaves basal, 2-3 (in my specimens) ; rather large, ovate 
or oblong, on long petioles; stem-bracts small, 2-4. 
Flower solitary, small, almost wholly green, apex of 
galea tinged with light brown, galea about 1.7 cm. to 
2 cm. long, erect, incurved, sub-acute; conjoined sepals 
erect, sinus acute, the finely subulate points embracing 
the galea, but not exceeding it; labellum oblong-elliptical, 
comparatively large, almost straight; irritable on a short, 
movable claw ; the apex shortly obtuse, and protruding 
through the sinus of the lower lip ; lamina about 9-11 
mm. long, traversed by a central raised longitudinal line, 
with a linear penicillate appendage at the base. 
Column about 12-14 mm. long, the upper angles pro- 
duced into long, erect subulate processes, the lower angles 
somewhat narrow, obtuse, inner margins ciliate ; stigma 
narrow, prominent ; anther prominent with a very short 
point. 
This small, but shapely-flowered species appears to 
be well-distributed throughout the forest areas of North- 
ern New South Wales and Southern Queensland.
