the name Euphysetes grayi, may be discerned at a glance the more immediate affinities 

 of the present species, which I propose to call Plii/seter (Euphysetes) simns, in reference 

 to its peculiarly short obtuse muzzle. 



Description of the Skull. 

 (Pis. XII., XIII., & XIV. fig. I.) 



Short as is the upper jaw in proportion to the skuU in Phoccma hrevirostris (PL IX.), 

 it is shorter in the subgenus or section of Physeteridce represented by the Physeter 

 breviceps, De Bl. (PI. XIV. fig. 3), and shortest of all in the present species (ib. fig. 1). 



In the following Table of admeasui-ements are given those of the Physeter {Euphysetes) 

 grayi, Macleay (the larger species which was stranded on the Maroobrah beach, near 

 kSydney, New South Wales, and the skeleton of which is now in the Australian 

 Museum of that city), with the few admeasurements appended by De Blainville to his 

 notice of Physeter breviceps, from the Cape of Good Hope^.
