 Hansen (1908, p. 15, pi. iii, figs, la-lg), as in Stebbing's arrangement of the genus.

C. elegans, Caiman, 1907b, p. 9, pi. ii. 



Occurrence. — Station 135. Spirits Bay, near North Cape, New Zealand. 

 Plankton, 3 metres depth. One male. 



Remarks. — The solitary male specimen (total length 6*4 mm.) resembles the 

 male syntypes of this species in the genera] disposition of the ridges on the carapace, 

 but differs from them in having the ridges much less prominent, the tubercles at the 

 lower corners of the lateral enclosed area inconspicuous, and the whole surface some- 

 what closely and coarsely granulated. The dorso-lateral ridges of the posterior 

 thoracic and abdominal somites are also less pronounced. The slight development of 

 the sculpturing of the carapace gives this specimen a certain resemblance to the males 

 of C. similis described below. 



14. Cyclaspis similis, Caiman. Fig. 4. 



C. similis, Caiman, 1907b, p. 12, pi. iii, figs. 1-3. 



Occurrence. — Stations 133, 135, and 136. Spirits Bay, near North Cape, New 

 Zealand. Plankton, at 20 metres, 3 metres, and surface. Four females, two males. 



. Remarks. — The female specimens (total length 4 • 7 mm. ) agree with the solitary 

 holotype in general form, except that the sculpture of the carapace is a good deal

bolder ; the later-al depressed area is more excavate, and the surrounding ridges are 

 stronger and meet above so as to enclose the area completely, while the anterior lower 

 and posterior upper corners of the area are marked by prominences. The surface is 

 everywhere sparsely tuberculated. In ovigerous specimens the first leg-bearing somite, 

 instead of being exposed only at the sides, is visible as a very narrow strip right across 

 the dorsal surface. 



The appendages, as far as they have been examined, are similar to those of 

 C. elegans, with a tendency to greater elongation of the distal segments. In the third 

 maxillipeds the distal lobe of the basis is more acute and much longer relatively to the
