Within the last few years considerable additions have been 

 made to our knowledge of New Zealand Crustacea, especially in 

 the Amphipoda and Isopoda, and as the literature of the subject 

 has become already somewhat scattered, we have thought it 

 advisable to draw up the following concise list, which we think 

 will prove serviceable to students of Carcinology. The syno- 

 nymy of most of the species is not given in detail, as such a 

 course would unnecessarily swell out the list, but it is as com- 

 plete as is needed. The distribution m the colony of each 

 species is given as far as it is known. 



It is probable that, as a result of renewed and more detailed 

 examination, some of the species here enumerated will have to 

 be struck out, particularly when more attention has been given 

 to the development and metamorphoses of the individuals, and 

 to the sexual differences. At the same time the number of 

 species yet to be described must be very large. One can hardly 

 make a collection, particularly of Amphipoda, in any part of 

 New Zealand, without coming across new and distinct forms ; 

 and when more systematic dredging is carried out than has 

 hitherto been attempted, the number of such undescribed forms 

 will be materially increased. 



Note. — Following Professor von Martens' suggestion, the specific name 

 neo-zelanicus has been adopted in place of all the various forms of the word 

 meaning "of" or " from New Zealand."

* While quite prepared to take my full share of responsibility for this 

 paper, I wish to state that the whole work of preparing it has been done by 

 Mr. Thomson. I have simply gone over his manuscript, adding fresh locali- 

 ties, and making a few suggestions and additions here and there, — C. C.
