posterior set marked so. It seems more probable that the part marked co was merely the 

 raised and reflected orbital part of a single plate, as in Albula, Notopterus and others. 



According to Tate Regan (1909a, p. 82; 1911a, p. 120), the Enchodontidse "fall into 

 the division Stomiatoidei [of the Isospondyli]; they agree with the Stomiatidae in the 

 structure of the skull and of the mouth." Smith Woodward (1902, p. 37), however, regards 

 the enchodonts as "closely related to the existing Scopelidse, Odontostomidae and Alepi- 

 sauridse," but distinguished from all of these by having the margin of the jaw formed partly 

 by the maxilla. 



Thus the Cretaceous Enchodontidse have been referred by one leading authority to 

 the stomiatoid division of the Isospondyli and by another to the scopeloid division of the 

 Iniomi — a fact that is in line with other evidence of the close interrelationships of these 

 orders. 



Sardinoides. — This Cretaceous genus (Fig. 84) is referred by Smith Woodward (1902, 

 p. 33) to the Scopelidce; it is in a general way intermediate in appearance between the
