No. l8.] TRIASSIC FISHES OF CONNECTICUT. 55 



Besides the two species we have just noticed, names have 

 been proposed for several others whose status is very uncertain. 

 Some are doubtless to be regarded as young individuals belong- 

 ing to one or the other of the above characterized forms, and 

 the types upon which others are founded defy adequate descrip- 

 tion. In the opinion of Smith Woodward, as remarked by him 

 in Part III of his " Catalogue of Fossil Fishes," the so-called 

 Catopterns minor Newberry is probably founded on immature 

 and variously distorted examples of C. redfieldi. Further, the 

 same author regards it as uncertain whether the type of 

 C. ornatus Newberry should be associated with this species or 

 some other. " The type," he says, " is a unique, much distorted, 

 small specimen from Durham, which seems to have been chemi- 

 cally eroded in such a way as to display the concentric lines 

 of growth in the scales" (loc. cit., p. 3). It should be said 

 with reference to this last statement that the concentric markings 

 of the scales, which seem to be correlated with a subovate form 

 of the latter, are to be seen only along a part of the flank, where 

 the body has been much twisted upon itself. They fail to show 

 in the impression which is visible of the opposite side of the 

 body; and these two facts taken together tend to strengthen the 

 belief that they are of accidental origin. 



Genus Dictyopyge Egefton. 



Distinguished from Catopterus only by the more anterior 

 position of the dorsal fin, which never arises behind the origin 

 of the anal.
