nuchipinnis of the family Clinidse is of the Labrid type, and resembles very closely that of 

 Cheilinus fasciatus of the Labridse, except in minor details. In the Ophidiiform division 

 of the Blennioidea, however, the otoliths are very large relative to the size of the fish and 

 give rise to the so-called "Brotulid" type, which is frequent among fossil forms occurring 

 in Tertiary formations (p. 125). The otoliths confirm the placing of Fierasfer in the divi- 

 sion Ophidiiformes. Fossil otoliths of Fierasfer are frequent in the Upper Eocene (p. 126). 



Anacanthini (Cods, etc.) 



According to Garman (1899), the families Zoarcidse, Ophidiidse and Brotulidse are 

 closely related to the Gadidae and Macruridae and belong in the order Anacanthini. Cocke- 

 rell (1916) finds that the scales of the Brotulidse resemble those of the Ophidiidae and certain 

 genera of the Gadidae, while Miss E. S. Trotter (1926) records several interesting physio-
