ritus, Eupomotis gibhosus and Boleosoma 

 nigrum olmstedi were also common. 



I have received a collection of the f ollovcing 

 from a stream draining Lakemont Park Lake 

 at Altoona, in Blair Co., on August 5, 1910, 

 V sent by Mr. H. L. Mather, Jr. Pimephales 

 notatus, Semotilus atromaculatus, Notropis 

 whipplii analostanus, N. cornutus, Rhinich- 

 thys cataract(B, B. atronasus, Exoglossum 

 maxilUngua, Catostomus nigricans, Erimyzon 

 sucetta oblongus, Schilbeodes insignis, Eupo- 

 motis gihhosus and Boleosoma nigrum olm- 

 stedi. The occurrence of R. cataractce is of 

 interest, and although locally abundant, I 

 have met with it in but few and widely sepa- 

 rated localities. Another instance was on 

 August 27, 1910, in the Bushkill Creek at 

 Easton, where I also found Anguilla chrisypa, 

 Semotilus atromaculatus, Ahramis cryso- 

 leucas, Notropis hifrenatus, N. cornutus, 

 Rhinichthys atronasus, Catostomus com- 

 mersonnii, Erimyzon sucetta oblongus, Boleo- 

 soma nigrum olmstedi and Coitus gracilis.
