The following is abridged from Forster's description of the Porpoise, to ~ 
which I attribute these skulls :— 
Teeth a Body straight, round, thickest behind ; head rounded, shelving 
in front ; beak, pointed, straight, attenuated ; lower jaw longest ; dorsal fin in 
middle of back, triangular falcate ; tail-lobes sub-faleate ; tail attenuated, 
keeled above and below ; pectoral lanceolate, scarcely as long as the beak. 
Greenish brown or rust colour above, white beneath, a white spot on the 
dorsal and pectorals. Length, 6 feet. (Gray, l.c., 248.) 
I have frequently seen a porpoise answering to this description, as far as 
could be judged from a boat, in Queen Charlotte Sound and Blind Bay.

Delphinus novæ-zealandiæ, Q. and G. Gray, l.c. 246. 
PLE IL 
The skull of a large porpoise cast ashore at Waikanae appears to belong to 
this species, but having a flat palate it must be removed from the genus 
Delphinus to Clymenia. It resembles C. euphrosyne, but has a more slender 
beak and a larger number of teeth in the lower jaw. 
Skull rounded behind, forehead sloping rather abruptly ; crests and nasal 
bones prominent and rough ; maxillaries spongy, expanded, posterior wing 
with horizontal and ascending areas ; intermaxillaries elevated, callous, a little 
expanded in the middle of the beak, not united, and wide apart in front. 
Triangle bounded by a callous ridge, very rough, extends beyond the 
hinder teeth ; blower small, equal to half the width at notch; palate flat ; 
length of symphysis of lower jaw equals one-third the width at the notch. 
Length sick i ks ao cae 19 inches.
