friend says—‘ The epigyne is oval, longer than broad, with a rectangular opening reaching 
from the base to two-thirds of its height upwards.”’* 
In the examples collected by Mr. Hamilton the epigynum conforms more nearly to 
M. kerguelenensis ; also, the lateral eyes of the second row are poised obliquely, while 
the anterior median eyes do not touch their lateral neighbours as depicted by Mr. Hogg.t

In fact, the eye formula is very like that of Cambridge’s species 
as suggested by the figures referred to may be due to the angle at which the specimens 
were viewed. Being confronted with these difficulties, I wrote to Dr. J. Allan Thompson, 
Director of the Dominion Museum, Wellington, inquiring as to the whereabouts of the 
type (MU. hamuiltonz) ; the latter, however, was not in the museum over which he has 
charge, but he very courteously interested himself in my behalf, with the result that 
Professor W. B. Benham, of the Otago University Museum, came to my aid. I wish, 
here, to record my sincere thanks to each of these gentlemen. Professor Benham, 
without hesitation or loss of time, forwarded me all his specimens of M. hamiltoni, 
including the type, for examination and comparison with my material. The following 
are my descriptions and figures of the eye formula and epigynum from the type:— 
Eyes.--Ocular area longer than broad. Eyes 8, in two strongly procurved rows 
of four each ; eyes of rear row about equal in size, and mounted on small black tubercles ;
