(Il(‘sptM‘0[)ithecuK), and the Taunts skull described by 
Prof(‘ssor Dart as Australopitliecns africanns. Xeander- 
thal man and llte famous Pithecanthropus skidl from 
Java were also discussed. Tliese remains were illustrat- 
ed by casts and lantern slides. Althou^jrh tliese literally 
'‘dry bones’* mi^ht not seem attractive, the subject was 
i most fascinatin*? one. and shoidd appeal to all natur- 
alists. The sio'nificance of some of these fossils bad been 
exapr^erated, and in one or two cases reconstructions had 
appeared in the ])opular press that were not strictly 
warranted by the evidence. Certain fossils were so 
fragmentary that their real significance was in dispute. 
There vms xindoubted evidence, lunvever, for the exist- 
ence of men /)r proto-men in the past that were far 
lower, and in several respects more ape-like, than the 
most primitive races livinjx to-day. It was also evident 
that the rang-e of vaviahility exhibited by men to-day. 
lemarkable though it was, Avas quite inadequate to 
aeeount for the greater divergencies found in the past. 
These facts, in the opinion of the lecturer, shed definite 
light on the ancestry of man. and, even on fossil evidence 
alone, afforded ])roofs of liuman evolution.

NOTF ACCOMPANYING EXHIBIT OF A BAG-MOTH 
(Thyridopteryx herrichii.) CASE FORWARDED 
BY MR. C. McKENZIE. YALEBONE 
CREEK, VIA ROMA. 
Hy R. Illidge. 
The larva of this particular species (Ihe male moth 
of which is very thinly scaled on the wings, and hence is 
somoAvhat bee-like in appearance) builds its long oval 
case of seA'en segments, each being strongly ribbed 
lengtlnvays, and connected Avitli a circular rib to)) and 
bottom, ft is suspended by a tube of silk from the anter- 
ior end, which is attached to a twig or otlier object, and 
has also another at the ])osterior end. Hotli these tidies 
are finely ])leated and ca]>able of considerable expansion ; 
the first is used by the larva for feeding pnrpo.ses, and 
can be detached, and the case moA^ed by it as required, 
until just before its change to i>upa it is firmly fastened 
down ; the second, or anal tube, is for the ejectment of 
frass, and also as hereafter described. 
The case of this species is composed of very strong- 
AvoA'en silk entirely free from tAvigs or leaves. Tn another
