Notropis boops Gilbert. PI. XVI, fig. 13. 



Head 3| to 4; depth 4 to 4§; D. iii, 7, i; A. iii, 7, i; scales usually 

 32, sometimes .34, rarely 33, 35 or 36 + 2, rarely 3; usually 5 scales 

 above 1. 1., rarely 6; usually 3 scales below 1. 1., occasionally 4; 13 

 to 15 predorsal scales, rarely 12; snout 3£ to 4 in head; eye 2f to 3^; 

 maxillary 2f to 3£; interorbital 2\ to 3£; teeth usually 0, 4-4, 0, 

 occasionally 1, 4-4, 1, rarely 0, 4-4,1 ; length If to 2| inches. Twenty- 

 eight examples from Blue River, Ind., and Limestone Gap, Indian 

 Ter. The former in some cases show inner edges of grooves on pharyn- 

 geal teeth crenate, but differ from Gilbert's account in that 23 show 

 uniserial teeth and all have 8 (iii, 7, i) branched anal rays. There 

 are mostly 3 scales below 1. 1. Limestone Gap examples show smooth 

 pharyngeal teeth, dorsal origin distinctly behind ventral origin or 

 midway between snout tip and caudal base, 1. 1. very slightly decurved, 

 and 14 or 15 predorsal scales. I do not now think these examples 

 can be identical with Alburnnops shwnardi Girard, 5 though pre- 

 viously listed them so, as it was virtually supposed to have teeth 

 2,4-4,2 or 1,4-4,2, besides minor characters. The figure 6 is faulty, 

 showing maxillary to eye center, mandible included, breast naked, 

 7 scales above 1. 1. (his description says 5), 5 scales below 1. 1. (his 

 description says 3). 

 Notropis hudsonius (Clinton).

 rarely iii, 6, i or iii, 8, i; scales usually 37, often 36, sometimes 35, 

 seldom 34 or 38, rarely 39 or 40 + usually 2, seldom 3; usually 6 

 scales above 1. 1., seldom 5; usually 4 scales below 1. 1., frequently 

 5; usually 16 predorsal scales, frequently 14 or 15, seldom 17, rarely 

 13 or 18; snout 3£ to 3| in head; eye 2^ to 3f ; maxillary 2f to 4; 

 interorbital 2f to 3^; teeth usually 2, 4-4, 1, sometimes 0. 4-4, 1, 

 occasionally 1, 4-4, 2, seldom 1,4-4, 1, rarely 2, 4-4, or 1, 4-4, or 

 2, 5-4, 1; length H to 3h inches. Seventy examples, from Berkshire 

 Hills, Mass.; Holston River, Va.; Port Clinton, O.; Lake Michigan,
