MARINE COPEPODA OF NEW ZEALAND. 47 
apex broad and bearing an even series of small teeth (fig. 5). Maxillee composed of four 
digitiform lobes (fig. 6), which are armed with numerous spine-like divaricate sete. 
Anterior foot-jaws laminar, bearing numerous lateral sete, but not divided into distinct 
lobes (fig. 7) : posterior foot-jaws two-jointed, basal joint short and stout, with three rigid 
spiniferous sete at the anterior distal angle; second joint forming a strong subtriangular 
hand, to the anterior angulated margin of which are attached two long stout sete, 
to the narrow distal extremity are hinged two long, biarticulate, slender ungues, which 
are armed with spine-like marginal sete (fig. 8). Two pairs of swimming-feet (fig. 9), 
two-branched, each branch consisting of a single broad lamina; distal and outer 
margins of the inner branch setiferous; outer branch with four large lancet-shaped 
spines on the outer margin, at the apex a larger spine, and on the inner margin three 
long sete. The cephalothorax is equal in length to the abdomen, and consists of 
three segments only, the first two being coalescent (figs. 1,2); the abdomen is two- 
jointed and suddenly narrower than the cephalothorax: to the posterior angles of the 
last thoracic segment are attached two small sete; angles of the first abdominal 
segments produced backwards, second segment twice as long as the preceding, con- 
stricted in front; caudal segments very short. Length 88 millim. 
Hab. Of this very interesting species two specimens were found in a surface-net 
gathering from Otago Harbour, and one in the net at 7 fathoms from off Gisborne. 
The specimen described by Mr. T. Scott under the generic name Saphirella seems 
to be, except as to the mouth-organs, very similar to the present, and I regret that, 
owing to the Saphirella having passed out of Mr. Scott’s hands, I have not been able 
to compare the actual specimens. Mr. Scott’s descriptions may be found in his paper 
on Entomostraca from the Gulf of Guinea (‘Transactions of the Linnean Society, 
2nd ser. Zool. vol. vi. pt. 1, 1894). 
[Closely allied to Pawrocope is a form represented in these gatherings by only two 
imperfect specimens, which, like Paurocope, were taken at the surface in Otago 
Harbour. I am unable, for want of suitable material, to give a complete account of 
this species, and it seems not unlikely that it may really represent the male of 
Paurocope, the general resemblance being very close, more especially in the swimming- 
feet and caudal lamine. ‘The antennules and antenne are, however, very different, 
but this difference, to a lesser extent, is likewise seen in the closely related genera 
Sapphirina and Corycwus. A very remarkable character is found in the presence of 
two simple lenses (ocelli) at the bases of the second pair of foot-jaws. Figures of the 
animal and some of its appendages are given in Plate XIII. figs. 10-17. 
Provisionally I propose the name Centromma thomsoni for this species. ]
