also flowing into the river close below this point, was thoroughly 

 exi:)lorecl and yielded interesting material. Though unnamed, it is 

 here referred to as "Tullytown Brook." 



In June, 1912, 1 visited Mr. F. J. Meyers at Bethlehem, in North- 

 ampton County, and made a number of collections from the streams 

 flowing into the Lehigh River in that vicinity. Mr. Meyers again 

 invited me to join him in this region in late May of 1913, when we 

 also made a few more collections. We then continued this excursion 

 to Pocono Summit and explored various streams in Monroe County. 



Mr. R. W. Wehrle sent several collections from Indiana and 

 Huntingdon Counties. 



In late July I spent a week in the lower Susquehanna region, 

 around Peach Bottom, in York County, and with the assistance of 

 Mr. H. L. Mather, Jr., secured several interesting collections. 



Various other collections of lesser interest, though some quite 

 extensive, have also been received during the past two years. 



Petromyzon marinus Linnseus. 



A young bluish example, taken in the shad-net at Tullytown. 



Lampetra aepytera (Abbott). 



Mr. Wehrle sent three small ones, though mature, from Hoffman's 

 Run in Indiana County. He writes: "There were a lot of them 

 sticking to stones in the riffles, and I think they were spawning. When 

 scared down stream they remained quiet a while, but soon returned 

 to stick to the same stones." Two others were also received from 

 him, taken in Brick Pond. All taken in April, 1913. 



Acipenser sturio Linnaeus. 



Two at the Tullytown Fishery. One, four feet long, taken early 

 in May, and the other taken May 28, a small example. 



Lepisosteus osseus huronensis (Richardson). 



Erie. 



Amiatus calvus (Linnseus). 



Five from Erie, one a female and others males. Stomachs nearly 

 empty, one containing small Perca flavescens. 



Pomolobus pseudoharengus (Wilson). 



Several hundred examined at Tullytown, from which about a dozen 

 copepods (Naobranchia pomolohi) were taken. The parasites were 

 all within the gill-openings. One adult female had a lernean, 

 Lerneoceropsis septemramosus, attached to its side below dorsal fin.
