4 INDEX FAUNAE NOV& ZEALANDI&. 



catalogue of the New Zealand Crustacea are the most important 

 papers. 



The German expedition for the same object visited Auckland 

 Island, when Dr. Krone collected a few Diptera and land 

 Mollusca. 



In 1879 Mr. E. Meyrick visited New Zealand, and for several 

 years collected and described the Lepidoptera. 



Meantime local naturalists had been very active. The New 

 Zealand Institute was established in 1868, and its annual volume 

 has always contained valuable contributions to the zoology of 

 New Zealand. 



Several descriptive catalogues, by different authors, were pub- 

 lished between 1871 and 1880. The first edition of Sir W. Buller's 

 Birds of New Zealand appeared in 1873, the second edition in 

 1888. Mr. G. V. Hudson's New Zealand Moths and Butterflies 

 in 1898. Other papers, in various publications, will be found 

 mentioned in the index. 



ELEMENTS OF THE NEW ZEALAND FAUNA. 



Omitting a few stragglers among the birds, fishes, and butter- 

 flies, which have failed to establish themselves, the New Zealand 

 fauna consists of two parts, one migratory, the other stationary. 



The migratory portion, which is very small, includes two 

 cuckoos and three or four species of Liiicol<z, which reach us 

 every October from the north through New Caledonia and Lord 

 Howe Island, and leave in or about March.* 



Among the list of fishes several names will be found of forms 

 which are properly inhabitants of warmer seas than those of New 

 Zealand, and are, no doubt, wanderers from the north. Such are 

 Lampris, J3raia, Sphynzna, Murtzna, and Ophisaurus. The 

 Mackerel (S. australasicus] and the Sprat (C. antipodum} are 

 irregular visitors to our coasts ; while two species, the Kingfish 

 (Seriola lalandii), and the Trevally (Caranx georgianus\ appear 

 to perform a regular migration, leaving us in the winter for the 

 north. But very little is as yet known of their movements. 



Of our fresh-water fishes, Retropinna richardsoni, Galaxias 

 attenitatus, and the Eels (Anguilla) migrate to the sea to spawn, 

 and the young fish ascend the rivers in the spring. The Lamprey
