1 Prior to the appearance of his Anatomv of Vertebrate Animals, in 1871, 

 Huxley homologized this bone with the squamosal of the higher vertebrates ; 

 later he accepted Parker's interpretation. 



2 From Erdl's plate and description I cannot be certain as to the identity 

 of this bone. Owen was evidently puzzled over it as I find in his MS. notes the 

 following: '■'Appears to be pterotic. Compared to outer auditory bone in 

 beaver."
