1901.] LARYNX or CEItTAJn!r WHALES. 279 



Flowei" and Lydekker, in tlieir text-book of "Mammals,'' state 

 that very little is known of the soft parts of this small 

 Cachalot, and it seems, therefore, worth while to figure, side by 

 side, corresponding views of the larynx of Gogia and Balcenoptera, 

 in order to bring out more forcibly the differences in this organ 

 between the Odontocete and the Mystacocete ; for, although the 

 text-books of earlier authors, such as Owen, Huxley, Stanuius, 

 and others, refer to the fact, yet in snch modern works as 

 "Wiedersheim no mention is made of it, and it may be that other 

 zoologists in the same case as myself will appreciate the differences 

 when presented pictorially. 



The young Eorqual was very evidently newly born ; the navel 

 had not healed up ; the umbihcal cord still remained attached to 

 the inner surface of the abdominal wall ; umbilical arteries and 

 vein still existed, and had evidently only recently been ruptured. 



I had a plaster cast made of half of the body of the animal, 

 intending to place the skeleton therein, in the way that the late 

 Prof, Flower had had carried out in the British Museum. I found, 

 however, that the bones were but slightly ossified and were of no 

 use for Museum purposes. 



The animal measured 9 ft. 9| inches in a straight line, from the 

 tip of the snout to the bottom of the caudal notch (10 ft. 1 inch 

 along the curve of the back). Its greatest diameter was 5 ft. 

 2| inches, at a distance of 5 ft. 7 inches from the snout. 



The specimen of Cogia only came into my possession a week 

 after it had been washed ashore. When I arrived at Purakanni — 

 about an hour's railway journey from Dunedin — I found that the 

 original finder had cut the animal about considerably. The blubber 

 from the back, including the dorsal fin, and the " spermaceti " 

 from the head, had been carried away, as well as the lower jaw and 

 the caudal fluke. The head had been very skilfully disarticulated 

 from the atlas, but had not been removed. The body had been 

 opened, and the viscera were lying about. The body and organs 

 were much mixed up with sand that had been blown over them. 

 However, I ultimately obtained the entire carcase, as well as most 

 of the internal organs. 



The specimen was a fully grown, and apparently adult, male ; it 

 measured 8 ft. 9 inches in a straight line from the tip of the 

 snout to the notch in the fluke ; of this the head occupied 16 inches, 

 ^. e. between one-sixth and one-seventh of total length. I did not 

 make any attempt to measure the girth. 



The pectoral fin was 14 inches long in a straight line, and 

 15 inches along the shghtly-curved anterior margin ; its posterior 

 margin presented a rounded angle 4 inches from the base and 

 8 inches from the tip, the distal moiety of this side being concave. 



The fin was 5 inches across at the base, 5| inches at its widest. 



The fluke, or tail-fin, was 27 inches from point to point ; the 

 median notch was 5| inches deep, and this point was 10 inches 

 from the plane of origin of the fluke from the tail, so that the 

 total length of the fin was 15 1 inches.
