IV PBEFACE. 



The classification followed in this Catalogue has been 

 mainly that of Dana. Though this arrangement is in certain 

 respects unsatisfactory, it has been thought advisable in a 

 work like the present rather to adhere to this widely accepted 

 classification, than to attempt any extensive modification of 

 it.* When the description of an author has been quoted 

 verbatim, or in an abbreviated form, his initials have been 

 appended. 



Mr. Haswell informs me that besides the works of the 

 earlier authors, he has been indebted in the compilation of 

 this Catalogue more especially to the memoirs of Dr. A. 

 Milne-Edwards, particularly his " Recherches sur la Faune 

 Carcinologique dela Nouvelle-Caledonie," and his " Etudes 

 sur les Canceriens," to Dana's " Crustacea of the U. S. 

 Exploring Expedition," to Heller's Crustacea of the " Reise 

 der Novara," to Spence-Bates' " Catalogue of the Amphi- 

 poda," and to the numerous Carcinological Memoirs of E. J. 

 Miers, especially his " Catalogue of the Crustacea of New 

 Zealand." He desires also to take this opportunity of 

 rendering thanks to those from whom he has received 

 assistance — more especially to the Royal Society of Tasmania 

 for kindly granting the loan of their copy of Dana's " Crus- 

 tacea," to the Hon. William Macleay, and to Prof. M'Coy, 

 for the^ loan of books and specimens. 



The letters A.M. indicate that the species is represented 

 in the collection of the Australian Museum.

*The direction in which to look for a more natural classification has 

 been recently well pointed out by J. E. V. Boas.
