Mr. J. G. Griffin. CE. — Dr. Cox remarked that amongst the sub-fossils 

 exhibited by Mr. Wilkinson, there was to him one of special interest, he 

 referred to the Syphonalia maxima Tryon. Hitherto this species had only 

 been recorded from Tasmania, but he had recently ascertained that it existed 

 also on the Victorian Coast near Port Phillip Heads. Dr. Cox considered 

 that this sub-fossil tended to confirm the hypothesis that a colder climate 

 prevailed at some not very remote period of this colony. The discovery also 

 of the Voluta papillosa, and Cyprea umbilicata for the first time on our coast 

 by deep sea dredgings, and alive, led Prof. Wyville Thompson to conclude 

 that these Molluscs had only migrated north, following some current of 

 water of the same temperature as these species which were found in Tas- 

 mania. — Dr. L en den f eld stated that he had discovered sensitive and 

 ganglia cells in the horny sponges, similar to those which he had observed 

 as occurring in calcareous Sponges. He gave a short description of these 

 cells, which were much larger than the corresponding elements of Calcareous 

 Sponges. — Mr. Macleay exhibited some Fresh Water Fishes, which he 

 had received from Mr. Charles Jenkins, L.S., of Yass. They consisted of 

 specimens of the genus Murraya Castelnau, an Oligorus of very remarkable 

 form, and a remarkably elongate Gadopsis, all from the Little River in the 

 Alpine Regions of the Murrumbidgee. Also, a species of Galaxias from the 

 Yass River. He stated his intention of describing them at the next meeting. — 

 Mr. E. P. Ramsay exhibited (1) some specimens of a new and large species 

 of Ostracode [Estheria) from the Clarence River, collected by Mr. Goodrich. 



(2) Two fungi from the vicinity of Mossgiel, received from Mr. K. H.Bennett. 



(3) A disc-shaped club of gold-bearing quartz, with sharp circular edge, 

 used by the natives of New Guinea, in the neighbourhood of Mount Astro- 

 labe. — Mr. J. D. Ogilby exhibited a new form of Blenny, allied to Cristi- 

 ceps and Climts, for which he proposed the new genus name of Pelraites. It 

 differs in the dental formula and fins. — Mr. E. G.W. Palmer exhibited 

 two Moths of the Family Bombycidae. The larva of one he found feeding on 

 the Green Wattle [Acacia decurrens). The larvae of the other, Chelepteryx 

 Collesii, on various species of Eucalyptus. The moths of this latter prove to 

 be all males, and took wing on the 6th of May in immense numbers in the 

 neighbourhood of Burwood. The larvae attain a great size and are covered 

 with sharp spine-like reddish hairs, which are used in spinning their co- 

 coons. — Baron Ma clay called attention to the fact that the surprisingly 

 low temperature of the blood in Echidna hystrix, to which he had previously 

 called the attention of the Society, had been observed by Professor Owen 

 forty years ago. 



Berichtigung. 



In meiner unlängst im Morphologischen Jahrbuche erschienenen Abhandlung 

 (Beiträge zur Kenntnis der Niere der Prosobranchier« schrieb ich Corvette »Chier- 

 ehia«, statt die Corvette »Vettor Pisani«. Wie schon Vielen bekamit sein wird, 

 ist Chierchia der Name des verdienstvollen Seeofficiers, der die Reise um die 

 Erde (?) auf diesem Schiffe eben machte. Dr. B. H al 1er.
