PREFACE. 
THis CATALOGUE has been compiled for the use of students 
and collectors in New Zealand, with the object of affording a 
classified list, with short descriptions of the families, genera, 
and species of Stalk- and Sessile-Eyed Crustacea, which lave 
already been found in the Colony. 
Like former Zoological Catalogues issued by the New 
Zealand Government, through the Geological Survey and 
Museum Department, this must only be considered as a pro- 
visional attempt to gather into a convenient form what is 
known on the subject, as ‘a preliminary to the collection of 
more ample materials. The only special list of the New 
Zealand Crustacea previously published, given in Dieffenbach’s 
“New Zealand,” in 1843, mentions only nineteen species of 
Stalk- and Sessile-Hyed Crustacea ; nearly forty are recorded 
from New Zealand by Dana, in his work descriptive of the 
collections made during Wilke’s Exploration of the South 
Seas in 1838-42, while the list has been still further increased 
through the results obtained by the French Corvettes “‘ Astro- 
labe and Zelée,” under the command of M. J. Dumont d’ Urville ; 
and during the short visit to New Zealand of the Austrian 
Frigate “Novara.” There still remain, nevertheless, a con- 
siderable proportion of the 140 species enumerated in this 
Catalogue which have been recognized as belonging to the
