 ably included in the composite Micropter- 

 us salmoides of Forbes (Sc Richardson, 

 Thompson O^c Hunt, and other early au- 

 thors. Their specimens are no longer ex- 

 tant. FR ?, TH ?. LS 14 (Salt Fork, 

 Middle Fork, Sangamon).

 crappie. — FR 4 (Embarrass, Salt Fork, 

 Sangamon), TH 2 (Sangamon), LS 16

 ern sand darter. — TH 2 (Middle Fork), 

 LS 3 (Middle Fork). 



Etheostomo asprigene (Forbes). Mud 

 darter. — Reported as Etlieostoma jessiae 

 by Forbes ^ Richardson. FR 2 (not 1 

 as stated by 'Fhompson & Hunt: Salt 

 Fork and Sangamon), LS 1 (Sangamon). 



Etlieostoma hlennioides Rafinesque. 

 Greenside darter. — Reported as Diplesion 

 hlennioides by Forbes 6c Richardson, 

 Thompson iSc Hunt, and other earlv au- 

 thors. FR 7 (Salt Fork), TH 10 "(Em- 

 barrass, Salt Fork, Middle Fork), LS 13 

 (Embarrass, Little Vermilion, Salt Fork, 

 Middle Fork). 



Etlieostoma caeruleum Storer. Rainbow 

 darter. — Probably included in the compos- 

 ite Etlieostoma coeruleum of Forbes & 

 Richardson; seven localities represented 

 among the 11 Thompson (Sc Hunt collec- 



tions still extant. FR ?, TH 7 (Embar- 

 rass, Salt Fork, Middle Fork), LS 7 

 (Kaskaskia, Embarrass, Salt Fork, Mid- 

 dle Fork). 



Etlieostoma clilorosomum (Hay). 

 Hluntnose darter. — Reported as Boleoso- 

 ma camurum b\ Forbes & Richardson, 

 Thompson (S: Hunt, and other early au- 

 thors. FR 1 (Sangamon), TH 1 (Kas- 

 kaskia). 



Etlieostoma flabellare flabellare ( Rafi- 

 nesque) X lineolatum (Agassiz). Fantail 

 darter. — Champaign County specimens 

 representing an intergrade population. 

 Material from the Sangamon is rather dis- 

 tinctly striped and approaches typical line- 

 olatum, whereas flabellare influence pre- 

 dominates in our series from the Salt Fork 

 drainage. Specimens from the other drain- 

 age svstems are intermediate in pattern. 

 FR 2 (Salt Fork), TH 16 (not 14 as 

 stated : Embarrass, Salt Fork, Middle 

 Fork, Sangamon), LS 18 (Salt Fork, 

 Middle Fork, Sangamon). 



Etlieostoma yracile (Girard). Slough 

 darter. — Reported as Boleiclitliys fusifor- 

 mis by Thompson & Hunt and known in 

 the county from only one specimen, still 

 extant, taken on lower Wildcat Slough. 

 TH 1 (Sangamon). 



Etlieostoma nigrum nigrum (Rafi- 

 nesque). Eastern Johnny darter. — Re- 

 ported as Boleosoma nigrum by Forbes & 

 Richardson, Thompson & Hunt, and other 

 early authors. We assign the Champaign 

 County material to the nominate subspe- 

 cies on geographical grounds. Material 

 from the Embarrass, Little Vermilion, 

 and perhaps the Kaskaskia is clearly refer- 

 able to EAlieostoma nigrum nigrum, but 

 large series from the Sangamon, Salt Fork, 

 and Middle Fork exhibit characters of 

 both E.. n. nigrum and E. n. eulepis Hubbs 

 (Sc Greene, and specimens from the Salt 

 Fork and Middle Fork of the Vermilion 

 display predominantly eulepis characters. 

 FR 1^ (Embarrass, Salt Fork, Sanga- 

 mon), TH 82 (all drainages), LS 80 (all 

 drainages). 



Etlieostoma spectabile spectabile (Agas- 

 siz). Northern orangethroat darter. — 

 Probably included in the composite Etlieo- 

 stoma coeruleum of Forbes & Richardson 

 and found in 4 of the 1 1 Thompson & 

 Hunt collections still extant. FR ?, TH 4 

 (Sangamon), LS 60 (all drainages).
