Genus Dictyopyge Egerton 



This genus is closely related to Catopterus, differing chiefly in the 

 more forward position of the dorsal fin, which begins a little in front of 

 the anal. The genus is widely distributed, being known by eight or 

 nine species, occuring in North America, Europe, Australia, and 

 probably also in South Africa. 



Dictyopyge macrura (W. C. Redfield) 



(PL 24, fig. 3; PI- 67) 



This is one of the rarest of North American fossil ganoids, known 

 by only one or two complete specimens and a number of fragments. 

 Until recently the type specimen had been lost, but it was lately 

 found by Dr. A. S. Woodward; it had been in use as a paper weight 

 in one of the offices in the British Museum. 



Dictyopyge macrura is known from only one locality— the Upper 

 Triassic shales, near Richmond, Va. Eastman^^ has referred to a 

 specimen in the Museum of Comparative Zoology at Cambridge, 

 Mass., (No. 2531), which is labelled "probably from Middle town, 

 Connecticut," and has accepted it as evidence of the occurrence of the 

 species in the Triassic of the Connecticut Valley. But to us this 

 specimen does not seem to afford conclusive evidence of the occurrence 

 of the species in Connecticut. The fact that the label reads "prob-- 

 ably," indicates that it was not written by the hand that collected the 

 specimens; or if so, only after so long an interval since it was collected,
