4272; Xo. 500, Lewis Point, 14; No. 501, Lewis Point, I ; Xo. 507. Upper South 

 Bay, I ; Xo. 522. Frenchmen's Island, 47; No. 526, Maple Bay, 8; No. 529, Dun- 

 ham's Island, I ; Xo. 543, Frenchman's Island, i. In late July the following collec- 

 tions containing small suckers were made from shallow water: No. 550, Godfrey 

 Point, 2; No. 585, Lower South Bay, 16; No. 605, Shaw's Bay, i. 



In September, 191 5, only three collections containing small suckers were 

 made in the lake : No. 76, Constantia, i ; No. 86, Poddygut Bay, 3 ; No. 100, Ladd's 

 Bay, 23. Fall collections made in October, 1914 and 1916, including small suckers 

 are as follows: No. 5, Lower South Bay, many; No. 305, Brewerton, 3; No. 413. 

 Brewerton, 3. 



In creeks connected with Oneida Lake we took small Common Suckers as 

 follows: No. 75, Scriba Creek and Frederick Creek, 13 specimens; No. 81, John- 

 son Bay Creek, i; No. 88, Chittenango Creek, 2; No. 516. Fish Creek, i; Xo. 

 546, Chittenango Creek, i; No. 593, North Bay Creek, 38; Xo. 621. Johnson's 

 Bay Creek, i. 



We collected only one Common Sucker from deep water, Xo. 519, taken in a 

 gill net set in 12 feet of water oflf Norcross Point. Some of those found dead 

 were preserved. Some specimens were obtained from the market ; they belong with 

 collections Nos. 129, 345, 351, 486, 560. 



Enemies and Disease. Lampreys attack this species in Oneida Lake, and 

 many with scars were found dead; some of these were preserved (Nos. 75, 

 92, 93, 518, 614). Fowler ('06, p. 158) tells of suckers being bored into by 

 lampreys (in all probability Pctromyzon marinus), in New Jersey. They are un- 

 doubtedly also eaten in large numbers by black bass and other predacious fishes 

 (Nash, '08, p. 29). One was found in the stomach of a Chain Pickerel taken at 

 Johnson Bay, July 11, 1916. Hankinson ('16, p. 145) noticed Pike {Esox luciits) 

 present in unusual numbers in the only part of a pond in the Whitefish Point 

 region which was frequented by these suckers, and where they were abundant. 

 Juday ('07, p. 166) found remains of this species in stomachs of Rainbow Trout, 

 Salmo iridens slmsfa, in Colorado. Hankinson ('17, p. 326) once saw a water 

 snake {Matrix sipedon) about four feet long capture a Common Sucker nine 

 inches long, in a shallow, rapid part of a stream in Illinois. Fowler ('13, p. 14) 

 found fragments of this species in a nest of a Kingfisher. Two (No. 31) were 

 taken from the stomach of an American Merganser at Cranberry Lake in the 

 Adirondacks, N. Y., August 21, 191 5, by C. C. Adams. These fish were about 5 

 inches long. The eggs are evidently eaten by Rlack-nosed Dace and darters during 

 the spawning time (Reighard, '20, p. 13). 



Wilson ('04, p. 131) found a copcjiod .liu/nliis catostonii attacking this 

 .species. Cooper ('20, p. 5) describes Glaridacris catostonii Cooper frnm this 

 sucker found in Douglas Lake, Cheboygan County, Michigan. Fowler ('14, ]). 

 350) records a large cestode, Dibcfthriuvi lifinla Donnadieu, in a large sucker of 

 this species. Larval trematodes were fminil in the eyes of Common Suckers from 

 Douglas Lake, Michigan (LaRue and othirs. '_>'), jj. 285; Butler, '19, p. 116). 

 In a stream in Ohio, Osburn ('01, \). \o) U<\\\u\ nmsi individuals of this species 

 attacked by leeches. Evermann and Clark ('jo, \ dl. 1, ]i. _>()_:;: \\<\. j. ]>. 7()) note 

 Arqulus catostowi Dana and llcrrick. and also leeches, on Conimim Suckers. \\'e
