REPLY TO THE PRECEDING NOTE. 113 
4.—That assuming that the mineral was Scolecite he did not 
intend to imply that the calcite had been immediately derived 
from it, but rather that the former, owing its presence in all 
probability—as according to Geikie is the case generally with 
other zeolites—to the existence of triclinic felspar undergoing 
processes of decomposition, indicated, by its presence in the 
Charters Towers granites, a probable source of the calcite in the 
triclinic felspar also.* 
EXEIBTYS: 
Amonst the exhibits, in addition to those illustrating the above 
papers, and which included the skull of Owenia grata, and speci- 
mens of both sexes of the banana mite and of species of the 
allied genus Tyroglyphus, was a curious fish—Opesthognathus 
Facksontensts—previously overlooked in Queensland waters, but 
recently found in Moreton Bay by Mr. D. O'Connor. Dr. Lucas 
also drew attention to four probably new butterflies belonging to 
the general Hypochrysops, Lyczna, and Hypsa (2 species), the 
first from Gippsland and the last from New Britain.
