tract for fittings, costing £ I (34 lis., was satisfactorily completed in Febru- 

 ary. Since then the Bacteriologist had been able to commence his prelimi- 

 nary work , an interim equipment having been arranged for at a cost of 

 £ 126. With the arrival of supplementary apparatus and chemicals ordered 

 in Europe and now on the way to Australia, and the completion of the tiling 

 of the floor which had been delayed by an accident to the contractor's plant, 

 the laboratory would be practically finished. The Society was to be congra- 

 tulated on the improvement in the Hall, and in its acquisition of a laboratory 

 of so satisfactory a character. In the capacity of trustee the Society was espe- 

 cially to be congratulated, since Sir William Macleay's intentions and direc- 

 tions were now on the point of realisation. The Society had given effect to 

 the trust; it now remained for the successive Macleay Bacteriologists to ju- 

 stify Sir William's conviction that the status of bacteriology in Australia 

 could advantageously be raised. — The main portion of the Address was 

 a consideration of the claims of "neo-vitalism" in favour of the conception 

 of purpose as a positive working hypothesis in biology. A comparison was 

 drawn between the methods and conceptions of morphology and physiology, 

 and reference was also made to the evidence for ultramicroscopical structural 

 difi'erentiation in living germinal material as possible basis of hereditary pro- 

 perties. — 1) Descriptions of new Australian Lepidoptera. By Oswald B.

 — 6) Contributions to the Morphology and Development of the Urogenital 

 Organs in Marsupialia. i. On the Urogenital Organs of Perameles, together 

 with an Account of the Phenomena of Parturition. By J. P. Hill, B.Sc, 

 F.L.S. The paper contains an extended account of the anatomy of the female 

 urogenital organs. Evidence is brought forward to show that these have 

 retained a more archaic character than is found in any other Australian Mar- 

 supial hitherto described, and that indeed the adult female urogenital organs 

 in Perameles are in a condition which can only be described as persistently 

 embryonic. The phenomena of parturition are described in detail, and it is 

 shown that the young reach the exterior by way of a median passage consti- 

 tuted in front by an extremely short epitheli ally canal — the common median 

 vagina — formed by the union posteriorly of the two median vaginal cul-de- 

 sacs, and behind by a relatively very long cleft-like slit, entirely destitute of 

 an epithelial lining — the pseudo-vaginal passage — lying in the connective 

 tissue between the lateral vaginal canals. — Mr. Rainbow exhibited on be- 

 half of Mr. E. G. W. Palmer, a living specimen of the spider Lycosa Godef- 



froyi, L. Koch, from Lawson. The specimen, a female, was covered with the 

 recently hatched out young. The spiderlings are always so carried by the fe- 

 male during infancy, but when old enough to forage for themselves, distri- 

 bute by the process of ballooning. The egg-bag or cushion is always carried 

 by these spiders attached to the spinnerets.
