Abstract of Proceedines, July 25th, 1906.- — Mr. G. A. Waterhouse 

 exhibited specimensof all the known Australian species oîOgyris [Lepidoptera: 

 Lycaenidae]. Commenting on the habits their larvae, he remarked that so far 

 all had been found to feed on various species of LorantJius, feeding by night 

 only and hiding during daylight under pieces of bark, in holes in the trees, 

 under stones on the ground, or even in ants' nests. Most of the species are 

 attended by ants, which seem to be very useful to them. About 7 o'clock 

 one evening he watched larvae of 0. ianthis marking their way from a piece 

 of LorantJtus to their hiding place. These larvae did not seem to have any 

 idea of direction, for they frequently attempted to go quite away from their 

 hiding place, but were prevented by the ants blocking their further passage 

 in that direction. — Mr. D. G. Stead exhibited a mature intra-uterine foetus 

 of the Little Saw-Shark Pristiophorus drratus Latham, and, for comparison, 

 the head of a half-grown example of the same species; and lie pointed out 

 that an examination of the rostral lamina or "saw," in the mature foetus of 

 Pristiophorus cirratus, revealed the highly interesting fact that it was armed 

 on each side, at regvilar intervals, with long spines only; there being none 

 of the small intermediate spines which are so characteristic of the ''saw'' in 

 the adult or in the half-grown specimen exhibited. In the possession of this 

 character, the foetus suggested the large predaceous Saw-fishes of the genus
