into the opposed regions of New Jersey along the southern part of 

 Delaware Bay, where it was found to be very abundant in several 

 streams. It is likewise very abundant in the fresh reaches of the 

 Indian River about Millsboro, where it was first discovered by Mr. 

 T. D. Keim and myself October 13, 1910. We secured many speci- 

 mens, and found it distributed well above the dams almost everywhere. 

 We also found but a single example in Mispillion Creek above the first 

 dam at Milford, on October 15, 1910, which is evidentlv the most 

 northern part of the State where it has yet been noted. As yet it has 

 only been found by us in fresh water. 



Tylosurus marinus (Walbaum). "Bill Fish." 



Ascends almost all waters in their tidal regions. Dr. Burgin found 

 it near St. Georges, the creek at St. Augustine, Mahon Beach and 

 Little Creek Hundred. Mr. Poole has found it in Rehoboth Bay. 

 It has been reported at Lewes and Delaware City. I have no examples, 

 and only examined a few in the markets. 



Eirtlandia vagrans (Goode and Bean). 



Reported from Cape Henlopen by Smith and Kendall, 15 who thought 

 this the most northern locality for the species at that time, though 

 Bean had recorded it as early as 1888 from Great Egg Harbor Bay in 

 New Jersey. 



Menidia menidia notata (Mitchill). 



Abundant along the coast, and reported at Lewes, Rehoboth and 

 Indian River Bays. Though I have no preserved examples, I saw a 

 small school at Dewey Beach during the past fall. 



Mugil oephalus Linnaeus. "Fat-back. Jumping Mullet." 



Abundant along the coast in the fall. A good food-fish and many 

 taken in nets for market. I saw over 600, taken in a single sweep of 

 the seine at Dewey Beach, on October 12, 1910. 



Mugil curema Valenciennes. " Fat-back." 



Very abundant at Dewey and Rehoboth Beaches, and though we 

 seined a great number on October 12, 1910, they were exclusively 

 this species, and all were quite small. 



Gasterosteus aouleatus Linnseus. 



Included on Bean's Wilmington record. 16
