requirements of the geologist collecting, arranging, and tabulating 

 the fossils he obtains, but the perfect and masterly manner in which 

 the authorities and references are enumerated with each genus and 

 species, not carelessly or scrimpingly, but liberally as to titles, 

 pages, and figures (rivalling H. G. Bronn's splendid ' Index Palaeon- 

 tologicus,' and Morris's ' Catalogue of British Fossils '), is evident 

 on every page, and gives a particular value to this laborious com- 

 pilation. The natural orders and families are carefully mentioned ; 

 and the best figures and descriptions, too, are specially indicated ; 

 and there are extremely few references which the author has not 

 himself consulted. 



The cordial recognition of every aid given to Mr. Etheridge in 

 the furtherance of this most valuable work is a pleasant feature ; 

 and the sympathetic and respectful mention of the labours of the 

 pioneers and promoters of Australian geology is most honourable to 

 our author, who has himself been an active labourer in that most 

 interesting and useful field of science.

Note on the Occurrence of the Genus Lymnasa in Australia. 

 By Alfred Brown. 



In a sketch of the " Geographical Relations of the New-Zealand 

 Eauna," in the ' Annals ' for January and February 1874, Captain 

 F. W. Hutton remarks that whUst the genus Lymnoea extends from 

 North America and Europe to India, China, and Java, it is not 

 found in Australia, reappearing, however, in New Zealand. Bearing 

 this statement in mind I was surprised, on examining a parcel of 

 freshwater shells brought home from Queensland by my brother, 

 to find certainly two, probably three, species of Lymncea mixed up 

 with the characteristic Physat and MeJanice of Queensland waters. 



One of the species is from Huntly Creek, Peak Downs ; the other 

 (or two others) are from the Isaac and Burnett rivers. 



That these habitats are strictly correct I have not the slightest 

 doubt, the specimens having been collected en route from Northern 

 Queensland to Sydney, whence the steamer brought the collector 

 direct home ; and the shells reached me packed in their native mud. 

 Further evidence of locality was found on breaking up a decayed 

 specimen, when a small example of a Physa common in the Isaac 

 river was found imbedded between the whorls. 



Whilst on the subject of Captain Hutton's paper, I may state that 

 Nautilus pompiUits, which he excludes from the Australian fauna, 

 is occasionally, but very rarely, found throwoi up on the beach in 

 the vicinity of Port Bowen, from which locality I lately received a 

 fresh example. Captain Hutton refers the " pipi " of the New- 

 Zealand natives to Chione Stiitchburyi, Gray (Wood's Cat. Suppl.
