No. 1 8.] TRIASSIC FISHES OF CONNECTICUT. 75 



inter-regional correlation of the Trias, based upon another class 

 of remains than fossil fishes, we may be permitted to refer at 

 this point to Dr. J. C. Merriam's elaborate memoir on "Triassic 

 Ichthyosauria, with special reference to American forms " (es- 

 pecially the chapter on Geologic and Geographic occurrence, 

 pp. 12-20).^ The evidence as to the age of the Triassic forma- 

 tion of eastern North America which is furnished by reptilian 

 remains (i. e., numerous footprints and a few skeletons of Dino- 

 saurs) will be discussed in a forthcoming Bulletin of the Con- 

 necticut State Survey by Professor R. S. Lull of Yale University. 

 In conclusion, the writer of the present article desires to 

 acknowledge his indebtedness and at the same time return hearty 

 thanks to the following named friends and colleagues who have 

 shown him many courtesies and placed numerous facilities at his 

 disposal, thereby greatly aiding the preparation of this Report:
