Hzocron.—0On the Dolphins of the New Zealand Seas, 211 
10. Clymenia obscura, Gray. 
Hector, Trans. N.Z. Inst., v., p. 160. 
This species was first described as a Tursio, and placed in the sub-genus 
Cephalorhynchus. By Gervais it is figured as an Electra (Lagenorhynchus 
breviceps), and altogether its synonomy is in a very unsatisfactory state. 
Yet it is not uncommon, frequenting the coast in large “ schools " in a similar 
manuer to the other small dolphin (Cephalorhynchus hectori), from which it 
is easily distinguished when swimming, by its high-pointed dorsal fin-lobe. 
Also it is uniform black above, white beneath, with a black streak over the 
eye. 
There is a stuffed skin, a complete skeleton, and some skulls of this 
species in the Museum. 
The number of vertebre is 71, viz., 7 cervical, of which the first two are 
united, 13 dorsal, 19 lumbar, 21 sacral, and 11 caudal. 
11. Clymenia euphrosyne, Gray. 
C. nove-zealandie, Hector, Trans. N.Z. Inst., v., 159. 
The skull which I described under the second of these names, I now 
decide, from having had access to better drawings, to refer to Gray's 
species as above. 
In the Museum we have also skulls of Clymenia dubia, Cuvier, and C. 
attenuata, Gray, but there is some doubt if they were captured within the 
New Zealand area.
