possessing its own genera and species, differing from the 
others. The finest kinds were in the ponds containing 
water lilies, and particularly in two where Utricularia vul- 
garis was abundant. On the stems of this latter plant I 
found that finest of all the infusoria, Stephanoceros Eich- 
hornii in great beauty : a species I had never previously met 
with in this district; there were also Floscularia ornata and 
cornuta, and in addition to abundance of the more common 
kinds I obtained Megalotrocha albo-ilavicans, Searidium 
longicaudum, Noteus quadricornis, Brachionus Polyacantlius, 
Limnias ceratophylli, &c., whilst among the decayed sedge 
leaves there were abundance of Qscillatoriae. 
It will interest all naturalists, and especially entomologists 
and lepidopterists, to hear that there has very lately been 
received in this country a fine specimen of the magnificent 
butterfly Papilio Antimachus, of which only one specimen 
was ever before brought to Europe : this Drury received in 
1775 from Sierra Leone, and it was figured by him and 
afterwards by Donovan, from the drawings of Jones, now at 
Oxford. The insect at the sale of Drury’s collection passed 
into the hands of Mr. Me Leay, at whose death it went with 
his collection to the Me Leay Museum at Sydney, where it 
is believed to be now. No other specimen has been seen in 
Europe until a few weeks ago, one came into the possession 
of my friend Mr. Christopher Ward, of Halifax, from a col- 
lection in the Cameroons district. The late Mr. Aspinall 
Turner, anxious to possess this fine and scarce insect, sent 
out some years since a good many drawings of it, with offers 
of five to ten pounds for every one captured, according to 
condition, and the same course has been equally pursued, in 
vain, by Mr. Hewitson and others, with. various collectors. 
It is very gratifying to learn that the species is not extinct, 
and as one specimen has reached Europe after the lapse of 
nearly a century, we may hope more will be forthcoming. 
Mr. Ward writes to me that it measures exactly 7J inches
