Oiiriilii Lake I'islus 345 



Notropis dcliciosus ((iirardi. Stkaw-hii.okki) Minnow. This species 

 Appeared to he very scarce in ( >nei(la Lake at the time our cnlleclions were made. 

 It is very similar to the Hlack-iiosed. the Hlack-chiiined, and the Uridled Min- 

 nows, hut the dark lateral stripe, is more prominent in these three fonns. It is the 

 sjiecies that has heen treated under the name of .\'olrof<is blcniiius (Huhl)S, '26, 

 ]). 42), and has JK-en confused in the literature with the very similar Xolropis 

 vol melius (Coi>c). 



UrtCiliiKj Habits ami Life History. There is little information on reconl 

 that a])plies with certainty to this species. Hubbs ("J3, p. 213) has made a careful 

 study of the species in Douglas Lake. Michigan. He found these fishes coming to 

 the shoals July 7; and that they spawned there was evident from the fact that 

 newly-hatched young began to api>ear there later, continuing on into August. 

 While the species a])i)arentiy l)ree<ls late in the season in Douglas I^ke, in more 

 southern waters like Oneida Lake, spawning probably occurs earlier. 



Distribution Records. Only three sjiecimens ( Xo. 416) were secured and 

 these were taken at Lakeport Ray, June 22, 1916.

Notropis dorsalis (.\gassiz). Gilbert's Minnow. The Gilbert's Minnow 

 is abundant, at least locally in Oneida Lake. We took a few in U>!6, but in 1927 

 we found large numbers at .Sylvan Meach. It is ])ossible that the species has 

 increased its numl>ers in recent years. 



Preediiu) Habits and Life History. <iravid females were ft>und by Forltes 

 and Richardson ('ex;, p. 140) in the latter i)art of June. 



Habitat. The sandy shallcjws of Sylvan Heach near the Imse of the pier, at 

 the mouth of F'ish Greek, seemed to Ik- a favorable habitat for the young of this 

 sjK'cies. Here large numbers of them were associated with adult Solropis atlteri- 

 uoides and .V. rubrifrons. Many were also found landliKked in wave fomud. 

 isolated pools (Coll. No. 4270 ) on the sandy ln-ach at the east end of the lake 

 (Figs. 217, 218). Greeley {'2J, p. 59) reports that this fish inhabits the larger, 

 warm tributaries of the Gene.sec River. Forljcs and Richardson ("09. pp. >4o and 

 • X) ciinsiiler the sinries as one inhaliiting small rivers and creeks. Jordan and 

 Fvermann ('•/>, p. 2'><>) say it is fmrnd in muddy streams from the DosMoines 

 River to the Platte. Meek ( ■<;2. |i. 2331 re])orts these nnnnows as living in clear, 

 rumiing water, in Iowa, and Fverniann and Cox ('«/>. p. 40.} », that they apjK'ar to 

 ]>refer small streams or rivulets with s;mi|y Inittom and with some current. 



I-ood. Greeley ( '2'. p. 5«>) examined the f<NM| of one s|H\imen 2 1 16 inches 

 long and found it to consist of chironomid larvae, fragments of three other insevts. 

 and some diatoms.
