at the upper end, and the increasing portion of the opening continued trough

Only one species is known, C. antipodarum Gray, from the seas 

 of New Zealand. In the court of the Museum of comparative Anatomy at 

 the Jardin des Plantes at Paris is preserved a complete and articulated 

 skeleton, unquestionably belonging to the known species of this genus, and 

 this is doubtless the same whose existence was reported to Gray by Milne- 

 Edwards. By the side of the skeleton is a smaller model in Plaster of 

 Paris of the whole animal , which however seems to us somewhat too slender. 

 The individual, a female, from which the skeleton has been taken, was 

 found in Acarva Bay, New Zealand, according to an appended ticket, which 

 bare the erroneous name Balaena australis. The present osteological notice, 

 the first published, of that genus, is founded on observations of this skeleton. 



4. Genus HUNTERIUS, J. Gray. 



According to the description given by FLOWER (loco citato) of the struc- 

 ture of the cranium,, it seems to approach that of the genus Eu balaena, 

 and it is therefore probable that the mouthopening agrees in its curvature with 

 that of that genus. Number of vertebrae about 56. The cervical vertebrae 

 are not all united, the posterior 07ies are free. Number of ribs about 15 pairs, 

 and the first pair remarkable for having the upper end cloven or biceps and 

 the lover end deeply hollowed out. Several of the anterior ribs differ from 

 those of the other genera in that the lower end is not thin and compressed , 

 but very thick, and his section is an oval, approaching a circle. The bla- 

 debone has both acromion and processus coracoideus distinct and fully developed. 



Only one species of this genus is as yet known, //. Temminckii 

 Gray, from the seas of the Cape of Good Hope. A cranium of an older 

 specimen and an almost perfect skeleton of a younger are preserved, accor- 

 ding to Flower, in the great museum at Leyden, and have been described 

 by Schlegel under the name of Balaena mysticetus antarctic a" 1 ). The corre- 

 sponding form of the ribs as also of the bladebone in the Swedenborgian 

 Whale, (the latter being provided with both acromion and coraeo'ide process) 

 incline us to range that Whale to this genus. We consider it probable, 



') The only ground that Gray has had for assuming the existence of this 

 genus, is the form of the tympanal-hone.
