waves of the sea after a storm. The whole surrounding country 

 is volcanic, and covered with grass, a few small patches of forest 

 showing at intervals. On crossing the river "Wai-roro," the 

 head water of the "Siga-toko," the bottom of which is covered 

 with large water-worn pebbles of various colours, and passing 

 through a native town situated on a small flat on the bank, one 

 commences to ascend a road over what appears to have been 

 coral once in a state of ignition. Blocks of this, resembling in 

 appearance the dead coral now found above high water mark, 

 have been piled on one another. They are dark in colour and 

 hard and brittle as glass, taking a high polish in the track, from 

 the friction of countless feet. After ascending about a quarter of 

 a mile, a small flat is reached at the foot of a cliff, and there in 

 apparently unburnt coral, the fossils are found. In this cliff is 

 the limestone cave in which Notopterus Macdonaldii is found." 



J. Brazier, Esq., C.M.Z.S., exhibited a Ca/rdiumfornicatus from 

 New Caledonia, and a Helix alholabris from New Bedford, United 

 States, sent alive through the post. 



G. Masters, Esq., exhibited a specimen of a Cirrirjede, Paradolcpas 

 Neptuni, from the gills of a common Port Jackson Crab, JVeptunus 

 pelagicus, from which it was originally described. The same 

 species has recently been received from Fiji, infesting the gills 

 of another Crab, Scylla serrata, which is also common in Port 

 Jackson. 



Dr. Head exhibited the proboscis of the Brazilian Sphinx 

 Macroglia cluentius, over 10 inches in length, which with probosces 

 of other genera of butterflies etc., were sent to him by Herr 

 Fritz Muller of St. Catherine, Brazil.
