 GoDMAN'y 1 ) no 3Toiviy noBOjy: ..Thalassogeron may be readily di- 

 stinguished from Diomedea, in so far as cranial characters are 

 concerned, in the much greater width of the interorbital région 

 of tbe frontals, and in the greater width of tbe palatine ends of 

 the pterygoids. Tbese characters sbarply define Thalassogeron 

 from Diomedea, but Diomedca melanophrijs présents in ail other 

 respects an extremely close resemblance to Thalassogeron, so 

 much so as to take it probable that this species has been wrongly 

 placed in the genus Diomedea. Like Thalassogeron, it présents a 

 peculiarly inflated lacrymae, and this seems to be met with in 

 no other member of the genus Diomedea. If D. melanophrys were 

 removed from Diomedea, than that genus would be very sharply 

 defined from Thalassogeron. But they are still separable on 

 account of the characters given above". Ec.in aoôaBHTB k-b
