 Creek, Wister Island, Keystone and Fishing Creek. 



Notropis photogenis amoenus (Abbott). 



Wister Island and Souderton. At the latter locality Messrs. 

 Mattern secured two adult examples, one showing the extreme 

 development of small predorsal scales. These scales number about 

 30, several more than in any count I have made of dozens of adult 

 examples from various streams in the Middle States. This variant 

 is still more remarkable, as the predorsal scales are more or less 

 uniformly small. In several adult examples small scales anteriorly 

 in the predorsal region may be noticed, though no example has yet 

 been seen with the appearance of the Souderton specimen. 



Notropis chalybaeus (Cope). 



Abundant at Bangor. This is the first record for Northampton 

 County, and as far up the Delaware basin as it is known to occur. 



Rhinichthys cataractae (Valenciennes). 



Lizard and Indian Creeks, Hereford, Lanark, Helfrich's Springs, 

 Jordan Creek, Elk View, W^est Branch of Big Elk and Little Elk 

 Creeks. Many specimens from the Jordan, Indian and Durham 

 Creeks are interesting, as being in brilliant spawning dress. All such 

 were secured in the autumn, and this indicates an exceptionally pro- 

 tracted spawning season. 

 Rhinichthys atronasus (Mitchill). 



New Tripoli, Sw^amp and Skippaek Creeks, Souderton, Lizard, 

 Coplay, Fell, Jordan and Indian Creeks, Lehigh River, Emaus,
