shells in 1784; and others, collected by the Forsters, were de- 

 scribed by Chemnitz in 1781-8, and Martyn in 1784. 



All this has complicated the nomenclature a good deal. 

 Speaking of the Fishes Dr. Gill says : ' It is to be remarked that 

 some of the species described by Forster have each received two 

 names. Schneider, with the propensity common in his time to 

 change a name because it did not seem to be as good a one as 

 could be given, substituting for Forster's one of his own which 

 suited him better. Nevertheless, Forster's, in every case but 

 one, was also given. Forster's names were therefore actually pub- 

 lished at the same time as Schneider's and in connection with 

 Forster's own descriptions. Whose names, then, shall be adopted 

 Forster's or Schneider's? Opinion has differed on this point, 

 some accepting Forster's, others Schneider's.* 



The next contribution to our knowledge was made when the 

 French corvette Coquille visited the Bay of Islands in 1822, when 

 the naturalists on board, 'MM. Lesson and Garnot, added three 

 new species of birds to our fauna. 



In 1827 the same ship, but now named the Astrolabe, ex- 

 amined all our outlying islands, and remained for some time in 

 Queen Charlotte's Sound. The naturalists, MM. Quoy and 

 Gaimard, were assiduous collectors, especially of Mollusks, and 

 their results were published by the French Government in 



1833- 



In 1840 Dr. E. Dieffenbach travelled through the North 



Island of New Zealand and the Chatham Islands for the New 

 Zealand Company, and the collections he brought back with him 

 were described by Dr. J. Gray and Dr. Richardson in the ap- 

 pendix to Dieffenbach's travels. In this book also Dr. J. Gray, 

 Director of the British Museum, gave a list of the then known 

 fauna of New Zealand. 



In the same year the United States Exploring Expedition, 

 under Captain Wilkes, visited Akaroa and the Bay of Islands, 

 and the birds collected were described by Peale in 1848; the 

 shells by Aug. Gould in 1852 ; the Crustacea by J. D. Dana 

 in 1855. 



In 1841 the French ships Astrolabe and Zelee visited the 

 Auckland Islands, Port Chalmers, Akaroa, and the Bay of Islands. 

 The records of this voyage, called Voyage au pole Sud, were pub-
