The description of D. nove-ze landic, to which I suppose the skull to 
belong, is as follows, and applies with deviations in colouring to a very large 
species of porpoise that frequents the West Coast Sounds and is known as the 
Cow-fish :— 
Teeth z ; body elongate, rounded in front ; beak cylindrical, flattened, and 
pointed; lower jaw longest; forehead rounded and prominent; dorsal fin 
large, triangular, rounded at tip; tail-lobes flattened, with a compressed keel 
between the base and the dorsal fin ; caudal small, nicked, cordate ; pectorals 
moderate, falciform. 
Above black-brown, edge of upper jaw and beneath dull white, with a 
yellow band from the edge along the side to beneath the dorsal ; tail slate 
colour ; pectoral and dorsal dull white, the latter with a dark edge. The 
lower jaw with small pores, and the body with small plates of regularly 
twisted white striz. 
Length 5 feet 10 inches, (Gray, Lc., 246.) ; but the Cow-fish reaches to at 
least 8 feet in length. 
CLYMENIA OBSCURA. 
Tursio obscurus, Gray, le. 264. 
TEL 
Skull much rounded behind ; crests feeble but sharp ; forehead slightly 
concave in outline ; maxillaries sloping on side of beak, constricted and rough 
before the notch, and with a slightly concave hinder wing ; intermaxillaries not 
elevated, tapering, callous, with a marked ridge bounding the triangle which 
extends to opposite the twelfth tooth from the back ; blowers very wide, equal 
to two-thirds the width at the notch ; symphysis of lower jaw short, equals one- 
fourth of jaw ; palate flat ; teeth a: 
This skull, obtained on the Wanganui beach by the Rev. R. Taylor, agrees 
with the figure and description of the above species. 
The body is described as black, with diverging streaks on the side, and 
whitish beneath. It has a distinct dorsal fin situated two-fifths from the 
snout ; the entire length being about 5 feet.
