186 THE VICTOBIAN NATURALIST. 



The Chairman also spoke of the Club's indebtedness to Mr, H. 

 P. C. Ashworth for having drawn the map of the Furneaux 

 Group, and provided the illustration, " The Gannetry on Cat 

 Island," in the February Naturalist, at his own cost, and moved 

 a vote of thanks to him for his generosity, which was seconded 

 by Mr. F. G. A. Barnard, and carried unanimously. 



PAPERS. 



1. By Mr, E. Anderson, entitled " Cocoon Makers and 

 Cocoon Breakers." 



The author gave original observations on the methods of 

 emergence of some of our hard-cocoon making moths. This is 

 accomplished in the genus Anthersea by the moth thrusting 

 sickle-shaped projections at the base of the wings through the 

 cocoon, at the same time revolving within, thus cutting its way 

 out. The paper was discussed by Prof. Spencer and Mr. 

 F. G. A. Barnard. 



2. By Mr. T. S. Hart, M.A., entitled " The Volcanic Rocks of 

 the Melbourne District." 



The author mentioned the different points of eruption near 

 Melbourne, and described the probable flow of the lava streams. 

 Sections show that the marine tertiaries overlie the older volcanic 

 rocks, of which there is probably a second series before the newer 

 volcanic. Some discussion ensued, in which Messrs. T. S. Hall, 

 M.A., and Pritchard took part. 



NATURAL HISTORY NOTES. 



A newspaper cutting was furnished by Mr. J. Gabriel on the 

 appearance in the Yarra of a fish declared to be Mountain Trout 

 (Galaxias). A note was contributed on the same subject by Mr. 

 H. P. C. Ashworth, stating that the fish were really sea fish, and 

 had been identified by Prof. F. M'Coy, K.C.M.G., F.R.S., as the 

 Tupong, Fseicdophritis Bassii, family Trachinidse, described 

 by Count Castelnau in "Proceedings Zoological Society of 

 Victoria," vol. i., 1872, from one specimen obtained in Bass 

 Straits. The fish have penetrated fifty miles up the river, and are 

 being caught in considerable numbers in the lower reaches. 

 Simultaneously with their appearance the Black Cormorant has 

 arrived in large numbers.
