noticed that it had a strong and most disagreeable odour, resembling 
decaying skins, or the castor of a horse. As the plant was new to me, 
I collected a large bunch, and wherever I went I was followed by num- 
bers of blowflies, which always took every opportunity of alighting upon 
the flowers. This year I had a bunch of Caladenia carnea on my table, 
and I noticed the same strong smell, especially on hot days ; it was 
also much frequented by flies, and although I did not actually see the 
fertilisation take place, yet it must have happened, as quite a number 
of flowers were fertilised, and the ovularies swelled and developed 
just as when fertilised in the natural state.

4. — AN TJNDESCEIBED SPECIES OF CHARON, WITH NOTES 
ON THE METAMORPHOSIS OF THE FIRST PAIR OF 
AMBULATORY LEGS INTO A PHYSIOLOGICAL PAIR OF 
FEELERS. 
By Dr. JOSEPH LAUTERER. 
The genus Charon was established by Karsch in 1879 from a 
fragmentary specimen, and was founded principally on the formation 
oE the maxillary palpi, resembling those of the Scorpionidce , but 
ending in movable claws instead of chela?. L. Koch, the editor of 
the Spider fauna of Australia (or rather Australasia), received a 
fragmentary specimen of Charon from Upolu which he described as 
Oh. c mstratianus , mentioning that the first pair of ambulatory legs had 
been broken off. I got a specimen of the same species from Mr. 
Tryon, where the left leg was preserved, and only lately I had the 
fortune to catch a specimen of a Charon near Brisbane under bark 
with the first pair of legs intact. These legs are nearly double as 
long as those of the second pair. They do not possess anything of
