fathoms from off Sheboygan, Port Washington, and Racine in Wisconsin, Michigan 

 City, Ind., and Manistee, Northport, and Traverse City in Michigan (records 9, 12, 

 16, 23, 28, 33, and 35). They were present, also, in a lift of special nets made from 

 8 to 12 fathoms in Platte Bay, Mich., on July 21, 1923, and in a lift from 6 to 16 

 fathoms off Traverse City, Mich., on July 25, 1923 (records 31 and 36). 



In the 4 to 4^ inch trout nets examples of the species were brought in at Wash- 

 ington Harbor, Wis., on August 18, 1920, from 20 to 24 fathoms; at Ludington, Mich., 

 on August 30, 1920, from 14 to 26 fathoms; and at Manistee, Mich., on August 28, 1920, 

 from 28 to 32 fathoms (records 3, 4, 27, and 29). At Sheboygan, Wis., on September 

 28, 1920, 3^-inch nets lifted from 35 to 40 fathoms had specimens also (record 8). 



From these observations it appears that reighardi, when not spawning, ranges 

 between 6 and 90 fathoms. These data do not give the outside limits of the range, 

 however. 



RELATIVE ABUNDANCE 



I have stated elsewhere, in discussing the relative abundance of other species 

 of chubs, that conditions were decidedly unfavorable during the collecting season 

 of 1920 for the accumulating of data necessary for conclusive statements on this head. 

 In those lifts of the chub nets mentioned in the preceding section no reighardi were 

 seeD. In most of the other chub lifts examined there were found only a few fish 

 of this species. Examples of the species were rare or found only occasionally among 

 the catches of other Leucichthys in lifts made on August 18, 1920, 4 miles west of 

 Boyer Bluff in 18 to 24 fathoms (record 1); August 19, 1920, 20 miles E. % N. of 

 Rock Island in 71 to 90 fathoms (record 5); August 23, 1920, 12 miles E. by S. of 

 the Sturgeon Bay ship-channel mouth in 60 to 70 fathoms (record 6); August 24, 

 1920, 10 miles E. by N. of Algoma, Wis., in 35 to 50 fathoms (record 7); September 

 25, 1920, 18 miles E. Yl S. of Port Washington, Wis., in 65 to 48 fathoms (record 11); 

 September 23, 1920, 27 miles ESE. of Milwaukee, Wis., in 60 fathoms (record 15); 

 September 3, 1920, 22 miles NW. by N. Yi N. of Michigan City, Ind., in 30 to 40 

 fathoms, October 11, 1920, 20 miles N. by W. % W. in 30 to 40 fathoms, November 

 8, 1920, 18 miles NNW. in 30 to 38 fathoms, November 19, 1920, 17 miles NNW. 

 and 173^ miles NW. by N. % N. in 28 to 32 fathoms, and on March 4, 1921, 15 miles 

 NW. by N. Yi N. in 28 fathoms (records 17, 18, 19, 20, 21, and 24); on October 4, 

 1920, 9 miles north of Point Betsie in 60 to 70 fathoms (record 30); August 10, 1923, 

 8 miles off Big Rock Point; June 29, 1920, 5 miles N. by E. of Charlevoix, Mich., in 

 40 to 55 fathoms; from an unknown locality on August 21, 1923 (records 37, 39, 41); 

 on June 22, 1920, 5 miles northwest of Cathead Light, Mich., in 40 to 60 fathoms 

 (record 32); and on August 12, 1920, 15 miles SE. by S. Yl S. of Manistique, Mich., 

 in 60 to 70 fathoms (record 43). In one lift examined at Michigan City on March 



2 1921, made 21 miles NNW. in 30 fathoms; in a lift made July 31, 1923, 5 miles 

 northwest of Cathead Light in 40 to 60 fathoms; and in a lift made August 11, 1923, 



3 miles NW. Yl W. of Charlevoix in 35 to 60 fathoms (records 22, 34, and 40), from 

 16 to 41 per cent of the catch was made up of reighardi. In a letter of April 25, 1921, 

 referring to 47 specimens of reighardi sent me for examination, taken on April 1, 1921, 

 off Michigan City in 30 fathoms (record 25), Robert Ludwig writes that about 30 

 per cent of the entire lift on that date were fish belonging to the species sent. A 

 sample of chubs caught on May 26, 1921, 8 miles northeast of Port Washington, Wis.,
