OF NEW SOUTH WALES. 377 



On the Fishes, among which are some beautiful and very 

 interesting forms, I hope shortly to offer some remarks, having 

 secured most, if not all, of the specimens obtained. 



Much credit is due to the Rev. Mr. Brown and Mr. Cockerell 

 for the aid they have given to science, and the great patience and 

 energy displayed in getting together such large and beautiful 

 collections of the natural history of these little known islands. 

 Having examined the whole of the collections so obtained, of the 

 birds and mammals, I estimate the number to be about 1500 

 specimens. The invertebrata I did not examine closely, but saw 

 sufficient of them to know that the Coleoptera alone must have 

 numbered several thousand : it contained some large species of 

 Curculionida? and Longicorns of many species. The Lepidoptera 

 consisted of several beautiful species of Papilio, Ornithoptera of 

 at least two species, and several belonging to the family Nympha- 

 Hdce ; a good number of the Pieridce and Daniidce. In all about 

 800 specimens or more. 



Of Mollusca there was a large number. I did not observe 

 anything striking among them, but some of the smaller species of 

 land and fresh water shells will probably prove new. I may 

 notice, however, the following from New Ireland and Duke of 

 York Island : — Helix Afacgregori (Cox) in great numbers, Helix 

 Lombei, Helix Nova-Hibernicce, and two other species, Partula 

 spadacea, Leptopoma vitrea ; Melanopus sp. ; Pythia, two species ; 

 Melania, six species ; and a great quantity of Cyclostoma keveus, 

 evidently a most common shell throughout the group ; besides a 

 new species of Ompludotropis. 



Among the Geological specimens from New Ireland were pebbles 

 of Jasper, Porphyry, and Porphyry conglomerate, specimens of 

 Coral and Calcareous-limestone, some nice crystals of Aragonite, and 

 lumps of Yellow Clay, Silicate of Alumina. The most interesting- 

 geological specimen obtained from New Ireland consists of a mass 

 of pure chalk, containing Globigerince ; this must be found in lai*ge 

 lumps, for Mr. Brown has presented the Museum with some rude 

 figures cut out of solid blocks about four feet in length, eight inches 

 in diameter, *nd fifteen inches wide, These images, although not
