what may be the form of the first ribs, or of the bones of the other parts of 

 the skeleton." 



The plates of baleen, in the Kawau specimen, presented by Sir George 

 Grey, are slightly longer than the dimensions given above, but the proportion 

 of -width to length is the same ; and the well-marked black margin 1 to |- of 

 an inch in width, clearly identifies the species. 



This interesting specimen, must therefore, be considered as unique, and 

 has been carefully figured in Plate 2b.

One small tooth imbedded close to tip of lower jaw on left side, one inch high ; 

 weight, 38 -8 grains ; irregular triangular shape. This is the skull of a young 

 animal. A strong ligament connecting the muscle of the forehead with the 

 snout is deeply imbedded in the intermaxillary groove. The snout is described 

 as long and flexible. Atlas and axis anchylosed. 



Length of cervical vertebrae, 3 '7 inches. Scapula, longitudinal diameter, 

 10 inches ; transverse diameter, 6 inches. Pectoral extremities, length, 14 

 inches ; width, 3J inches. Hyoid arch, 55 by 4 inches high. Pelvic bones, 

 2 J inches. 



The specimen was cast on the beach of the "West Coast, near Porirua 

 Harbour, and was prepared by Dr. Knox. 



Only two other specimens have, hitherto, been obtained ; the first at 

 Akaroa in 1846, now deposited in the Paris Museum ; the second was 

 captured at the mouth of the Avon, and prepared by Dr. Haast, for the 

 Canterbury Museum (see Art. 45, p. 190). 



A fourth, and very large specimen, has been lately stranded in Wellington 

 Harbour, and, in part, secured for the Museum by Dr. Knox, who, from his 

 examination, has some doubt of the identity of the above species, founded on 

 the character of the teeth.
