MARINE SHELLS OF THE CHEVERT EXPEDITION — HEDLEY. 1 2 1 



A REVISION OF THE TYPES of the MARINE SHELLS of 

 THE CHEVERT EXPEDITION. 



By Charles Hedley, Concholoaist. 



(Plates xvi. - xvii.) 



The largest collection yet made of the marine mollusca of tropical 

 Queensland, is that taken under the direction of Sir William 

 Macleay, in 1875, by the staff of the " Chevert," and now in 

 the Macleay Museum, Sydney. This collection was partly des- 

 cribed by Mr. J. Brazier in the earlier volumes of the Proceedings 

 of the Linnean Society of New South Wales. 



Later writers, who have studied the marine mollusca of this 

 region, have failed to identify species therein described, and have 

 complained that the account given is inadequate for recognition.^ 

 In fairness to the Sydney Conchologist, it should be remembered 

 that a debased style, dispensing with figures or dimensions in 

 diagnoses, introduced by the Brothers Adams, then prevailed in 

 London, and naturally lowered the level of work abroad. 



It has resulted that recent Monographs include the names of 

 the "Chevert" shells among the doubtful or unknown species. 

 Where these species have been again taken, they have in several 

 cases been described and named anew. 



My intention has been to correct synonomy, and to rehabilitate 

 neglected species. The "Chevert " novelties are treated in the 

 order in which they were described, under the names which I 

 consider they ought now to bear. As the drawings and measure- 

 ments now given, in addition to details already published, should 

 suffice to indicate the species, I have held redescription to be 

 beyond the limits of this article. 



I am indebted to Professors Haswell and David, custodians of 

 the collection, for permission to examine the types and to embody 

 the results in the present paper. To these gentlemen, and to Mr. 

 George Masters, Curator of the Macleay Museum, my thanks are 

 due.
