Caperea antipodartun (page 101). 



There is a nearly complete but not articulated skeleton, of a whale 

 taken on the coast of New Zealand, in the court of the Museum of 

 Comparative Anatomy at Paris, which M. Serrcs has named BaJcena 

 australis ; but Professor Lilljeborg observes that " it is an entirely dif- 

 ferent species, and without doubt the Eahalcena antipodarinn of Gray. 

 The bladebonc is of a very distinctive form, and has the rudiment of 

 an acromion. The car-bones are lost." The bladebone, according to 

 the di-awing that il. Lilljeborg sent to me, " is triangular, as wide at 

 the upper end as the length of the bone, and the rudimentary acro- 

 mion is a small protuberance about one-third from the upper edge." 

 — Letter from Professor Lilljeborg, 1865. 



The beautiful preserved skeleton, with all its whalebone, in the 

 Paris Museum, wliich was prepared by a Captain of the French Navy 

 on the coast of New Zealand, greatly resembles the skeleton of the 

 Cape whale described by Cuvier as B. australis. It has the smaller 

 head, square nasal bones, and simple (not forked) first rib of that 

 animal. In the latter respect it differs entirely from the skeleton of 

 B. australis in the Leyden Museum. — W. Flower s Notes, Oct. 1865. 



MACLEAYIUS (pages 78 and 103). 



It appears from further information and additional jAotographs 

 that I have received from Mr. Krefft, that I misunderstood his letter 

 and the photograph ; and the section that I have formed in the family 

 Balcenidce for a genus with a separate atlas, and the observations I 

 have made on it, are all a mistake : the atlas bone is entirely 

 soldered to the rest of the mass, as in other Baleenidce. This is to 

 be regretted ; but still the form of the atlas is so distinct from that of 

 any other known genus of Balcenidce, that I beheve the Australian 

 Right "VSTialo will be a distinct genus, to which the name Macleaijius 

 may be properly applied, and it is no doubt a true Balcenida. 



Mr. Krefft has sent the two following figures (p. 372) to further 

 illiistrate the mass of cervical vertebra; to which the name Madeayius 

 Australicnsis has been attached. 



The additional photographs confinn the opinion that the cervical 

 vertebraj are allied to those of the family Bcdcenidce — so much so that, 

 if Mr. Krefft had not sent it to me figui'ed with separate atlas placed 

 in front, I should have believed that the mass was the atlas and 

 cervical vertebra; of a Balcenida agglutinated in a single body, as is 

 usual in that family. 



This similarity did not strike me so forcibly until I saw these 

 additional views, especially the one that shows the hinder part of 

 the lateral processes of the anterior cervical vertebra of the mass, 

 fig. 74. . 



In describing from drawings and photographs, one labours under 

 considerable difficulties ; yet such is the extraordinary absence of 

 knowledge on the subject of the larger whales, that it is better they 

 should be noticed and figured until more complete skeletons can be 

 obtained.
