SPERM WHALES 189 



The skull appears to agree with de Blainville's 

 figure. The V-shaped lacrymal was especially plain, 

 and characteristic as compared with Owen's figure 

 of " Physeter siums" 



Gray suggests that this species is perhaps the same 

 as Euphysetes macleayi of Krefft.* I think that this 

 determination is correct. Krefft gives the same 

 number of vertebrae, save for the addition of a 

 twenty-sixth caudal, a difference obviously of no 

 importance. But it must be admitted that the 

 number of phalanges in the hand are not the same. 

 But the figure illustrating this point in his whale is 

 of a young whale, a fact which may account for some 

 discrepancies. 



Kogia simus, Owen,f has nine teeth on each half 

 of lower jaw ; two in upper jaw. Vertebral formula : 

 C. 7; D. 14; L. 5 ; Ca. 24 = 50. 



This species, which inhabits the Indian Ocean, 

 where it was first observed by Sir Walter Elliot, has 

 been by Dr. Gill relegated to a distinct genus, largely 

 on account of the peculiar swollen appearance of the 

 mandibles. The name which he proposed for this 

 genus is Callignathus. This does not seem to be at 

 all necessary, as the whale is so definitely a Kogia, 

 and as the genus contains at the most so very few 

 species. However, it seems to be a distinct species, 

 and cannot, I think, be confounded with K. grayi, 

 with which species Dr. Gray united it.
