24 
at least fourteen days after its arrival. One of the Black 
Cockatoos ( C alyptorhynchus funereus Shaw) was seen, and from 
the general behaviour and noise made by the flock, preparations 
were clearly being made' for breeding. The Rosehill Paroquet 
( Platycercus eximius , Shaw) was very plentiful and in tine feather. 
The Sassafras Tableland, and more particularly the immediate 
neighbourhood of the Mount itself, is a well known locality for 
certain birds. For instance, the Gang-Gang ( Gallocephalon 
galeatum , Latham) in small hocks of live to seven individuals 
was seen on several occasions, and specimens obtained ; the King 
Parrot (Aprosmictus scapulatus , Bechst.) seen but not captured, 
and evidently now rare there. The Laughing Jackass ( Dacelo gigas , 
Bodd.) was found to be very plentiful, and in good feather. The 
specimens shot appear to be liner and of larger size than those 
usually met with in more open forest country. The Wonga-Wonga 
(Leucosarcia picata, Latham) was well known here, but this line 
pigeon has been almost exterminated. One example of the rarer 
Scrub-Thrush ( Geocichla lunulata , Latham) was shot in the vine 
scrub by Mr. Alfred Stuart. The White-winged Corcorax ( Corcorax 
melanorhamphus , Yieillot) was common in large Hocks, and very 
tame. The pleasant note of the Brown Thrush ( Collyriocincla 
harmonica , Latham) betrayed its presence throughout the more 
open ground near the summit of the Mount ; and the Coach- Whip 
(Psophodes crepitans , Y. & II.) was equally noticeable by its 
peculiar and characteristic note. The Satin Bird ( PtUonorhynchus 
violaceus , Yieillot) frequents this locality in large flocks, feeding 
on the berries of the wild raspberry, and always accompanied by 
a few old full plumagcd males. Lastly, the rocky gullies and 
escarpments afford excellent cover for the Lyre Bird (Menura 
superba , Davies), which undoubtedly exists here in certain spots 
in large numbers, and I would more particularly point out the 
neighbourhood of the Bulee Gap. We heard them in great force 
hero when passing through on our way up from Nerriga. 
Little need be said of the Reptilia. Our specimens have been 
named by Mr. J. Douglas Ogilby, who has determined amongst 
the frogs Lyynodynastes dorsalis , Gray, from Mayfield, and 
L. tasmaniensis , Keferst., from the Sassafras. Numerous examples 
of Pseudophryne bibronii , D. <fe B., from both localities, and a 
few individuals of the rarer frog Crinia signifera , Girard, also 
from Mayfield, and the Sassafras. The Lacertilia are numerously 
represented by Lygosoma musifelinum , 0 J Shaun., a number of 
other forms of the same genus, at present unnamed, and an 
example of Egernia kiugi , Gray. 
Insecta. — Throughout the whole Silurian area between Tarago, 
Mayfield, and the Bulee River, the prevalence of white-ant hills is 
a very marked feature, some reaching as much as seven feet high. 
They are conical in shape, spreading at the base, and usually of a 
light yellow colour. On the Sassafras Tableland the “hills” become
