PSBUDORCA MBRIDIONALIS. 



Tasmanian Black Fish. 



F. Ttieridionalis (Flower), Gray, I.e. 291. 



Teeth, jj^ ; head rounded, scarcely beaked ; black on back and sides, 

 lighter below ; male head larger than female j head obtuse, like that of a 

 Sperm Whale ; pectorals small j dorsal hook-shaped, situated one-third the 

 total length from the tail ; teeth conical, acute, very large ; compressed on the 

 sides; skull rounded; beak short, tapering; intermaxillary broad. (Gray.) 



An imperfect skull in the Colonial Museum appears to resemble this 

 species. The occipital area is rounded and tumid without any marked crests 

 or ridges. Its length is 9 inches, and the width at the notch is 13 inches. 

 The whole of the beak is wanting. The bones of this skull have a soft 

 porous texture. It was picked up in Lyall Bay. 



To this species I also refer the skeleton of a young animal found on the 

 Kaiapoi beach, and now being prepared for the Canterbury Museum. The 

 teeth ^ — ^ are rather widely set, black in colour, incurved, and many of 

 them split longitudinally. 



GRAMPUS RICHARDSONI. 



G. richardsoni, Gray I.e. 299. 



Teeth 1 — 1', lower jaw straight, regularly diverging, scarcely bulging on 

 the side behind, united with a rather long, wide symphysis, obliquely truncate 

 in front, with a rather prominent tuberous gonyx ; teeth far apart, conical, 

 tapering at tip, but sub-cylindrical at base. 



Animal unknown. Cape seas. 



A lower jaw obtained on the Manawatu beach, and placed in the Museum 

 by Dr. Bailer, appears to agree with the above, but has only three teeth on 

 each side. 



Its length is 15 inches. 



BELUGA KINGII. 

 B. kingii, Gray, I.e. 309. 



10 



Teeth 3 ; head rounded ; teeth conical, hooked, often truncate, the upper 

 ones often wanting ; no dorsal ; skull with nose and outer wing of maxilla 

 bent over the orbits, making the forehead very convex ; beak short, not half 

 the length of the skull, and scarcely longer than the width at the notch ; 

 skull, entire length 13*5 inches; beak 5-5 inches; width at orbits 8 inches, 

 at notch 4-5 inches. (Australia.)
