38 DE. G. S. BEAD? ON THE 



no doubt that this is the species named by him Labklocera cervi. Dr. Kramer says 

 that the abdomen of the female is two-jointed, and in some specimens I have found 

 the abdominal segments so interfused that it is difficult to make out the number : 

 there may, indeed, be no visible separation, but in some there are distinctly four 

 segments. In the allocation of joints to the right male antennule, I have followed 

 Dr. Giesbrecht (Labidocera nerii, &c), not having myself been able to make them out 

 distinctly in the New Zealand specimens. 



Family CYCLOPID.E. 



Genus Ciclops (O. F. Midler). 



1. Cyclops ewaeti G. S. Brady. (Plate X. figs. 15-17.) 



1888. Cyclops ewarti G. S. Brady (3), pi. viii. figs. 1-6. 

 1891. „ „ idem (4) pi. vii. figs. 4-7. 



One specimen of a Cyclops which I cannot in any way distinguish from C. ewarti 

 was found in a surface-net gathering from Otago Harbour. 



This capture is peculiarly interesting, inasmuch as the species was originally described 

 from specimens taken in the Firth of Forth, and it seemed doubtful whether they 

 might not have made their way thither from some neighbouring freshwater habitat. 

 No other instance is on record, so far as I know, of a true Cyclops having been found 

 living in the sea, and it is very remarkable that this New Zealand example, of the 

 purely pelagic character of which there can be no doubt, should belong to the same 

 species. 



I have thought it well to figure here some of the parts of the Otago specimen. 

 The only difference between it and the Scottish examples is the greater width of the 

 abdomen, which may, however, be accounted for by pressure. An interesting peculiarity 

 of the species, in which both northern and southern forms agree, is the bipectinate 

 character of the terminal spine of the inner branch of the fourth pair of feet (PI. II. 

 fig. 17 a). In all other species these pectinations are represented by very fine setae. 



Genus Oithona Baird. 

 1 . Oithona spinifeons Boeck.

„ G. S. Brady (2), p. 90, pi. xiv. figs. 1-9, pi. xxiv A. figs. 1, 2. 



Frequent in surface gatherings from Otago Harbour, and in the tow-net at 7 fathoms 

 off Gisborne. 



I cannot distinguish these specimens from those which I have already (loc. cit.) 

 described and figured under the above name. Dr. Giesbrecht disagrees with my
