The description of D. novce-zealandAce, 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 -^ ; 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 j 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 wliite striae. 



Length 5 feet 10 inches, (Gray, I.e., 246.) ; but the Cow-fish reaches to at 

 least 8 feet in length. 



CLYMENIA OBSCURA. 

 Tursio ohsGurus, Gray, I.e. 264. 



PI. I. 



Skull much rounded behind ; crests feeble but sharp ; forehead slightly 

 concave in outline j 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 j blowers very wide, equal 

 to two-thirds the width at the notch; symphysis of lower jaw short, equals one- 

 fourth of jaw j palate Jlat ; teeth ||. 



This skull, obtained on the Wanganui beach by the Rev. E. 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.
