heavier than the former. Nutrient matter must, therefore, be 

 supplied to the foetus from the uterine wall, and, as there is no 

 placental connection, this must take the form of secretion from the 

 wails of the uterus, which contains close-set, long, vascular villi, of 

 a nutrient fluid, and its reception by endosmosis into the yolk-sac. 



NOTES AND EXHIBITS. 



Mr. Haswell exhibited specimens of intra-uterine foetuses of a 

 wallaby received through the Town and Country Journal, from a 

 correspondent in the interior. The foetuses were well-advanced, 

 nearly as large as mammary foetuses, and the chorion extended 

 over the whole surface, but there was still no trace of concrescence 

 with the wall of the uterus. 



The Hon. J. Norton, M.L.C., exhibited a portion of Hawkes- 

 bury Sandstone, from Springwood, Blue Mountains, which had 

 been perforated in all directions and to a considerable depth by 

 some hymenopterous insect. Such perforations are common 

 enough, but it is believed that the particular bee which forms 

 them has not yet been determined. 



Mrs. Masters exhibited an egg of the Paradisea raggiana from 

 New Guinea. "Very few of them have ever been seen. 



Mr. J. J. Fletcher, M A , B.Sc, exhibited several specimens cf 

 a Giant Earthworm from Burrawang, N. S. Wales, which is closely 

 allied to the Megascolides australis from Gippsland, Victoria, 

 described by Professor McCoy, in 1878. Mr. Fletcher stated his 

 intention of giving a further account of this worm at a future 

 meeting. 



Mr. Ratte exhibited fossils of the genera Rostellaria, Fusus, 

 Pleurotomaria ? Belemnites, Venus, Nautilus, from the interior of 

 New Caledonia, together with a fragment of bone. He observed 

 that these fossils were characteristic of the upper cretaceous 

 formation, and were likely to identify these New Caledonian beds 

 with some already known in New Zealand. He also exhibited an 

 Inoceramus from thf Neocomian of Noumea.
