posed of a single layer of cells with conspicuous oil-dops, and numerous 

 stomata, present on both surfaces, each with two subsidiary cells, and 

 level with the other epidermal cells. The mesophyll is composed of green 

 cells with few air-spaces. The parenchyma cells surrounding the vascular 

 bunches contain a little chlorophyll. In being thick and iso bilateral, and 

 in having a small amount of air-space, the leaf shows characters of a 

 heliophyll.

Art. XXVII. — The Nomenclature of the Birds of New Zealand : being 

 an Abstract of Mathews and Iredale's " Reference List." 



By Professor Bbnham, M.A., D.Sc, F.R.S. 



[Read before the Otago Institute, 7th October, 1913.] 



An important paper on the names of our birds was published in the Ibis 

 for April and July of this year, by Messrs. G. M. Mathews and Tom Iredale, 

 under the title of " A Reference List of the Birds of New Zealand," which 

 deserves to be summarized for the use of our naturalists to whom that 

 journal may be difficult of access. 



The authors have been able to examine a large series of almost all the 

 species enumerated by Buller in the Supplement to his " Birds of New 

 Zealand," which contains a complete list of all the birds, native and visiting, 

 which have been recorded as occurring in our islands or seas. At the same 

 time they have been in a position to examine critically the literature in a 

 way that was impossible to the early workers in this country. Further, 

 in many cases the original specimens, or " types," have been compared 

 with the descriptions given by the zoologists by whom the specimens were 

 named ; and it appears, in short, that no trouble has been spared to make 

 this new list as correct and complete as possible.
