The clue to the relationships of this strange fish has, I believe, been supplied by Pro- 

 fessor Starks, who in his recent work (1930) on "The Primary Shoulder Girdle of the Bony 

 Fishes" figures without special reference the strange pectoral girdle and actinosts of Cal- 

 lionymus on page 222 facing the figure on page 223 of the corresponding parts in Notothenia.

Nowhere else, so far as known, than in these two families does the scapula form such a 

 bridge between the three expanded actinosts. Evidently in its shoulder-girdle Callionymus 

 is merely a highly specialized notothenioid, and a comparison of the skulls seems to me to 

 strengthen this hypothesis.
