morning, or when the air is cool, they lie sluggishly 

 on the bottom of the cage, or under a rock, and at 

 such times they are of this dark color and show 

 no desire to feed. When the sun strikes their cage, 

 however, they scramble around in a lively manner, 

 their lighter colors begin to show, and they snap up 

 meal worms eagerly. 



They are good feeders, quite, hardy, and are 

 very gentle, never offering to bite.

FISHES IN THE WATER-SUPPLY OF 

 WILMINGTON, DELAWARE. 



On April 15, 1910, we visited Mr. Alfred P. 

 Poole at Wilmington, who offered us every oppor- 

 tunity to examine the fishes in the filter-beds. 

 These are fed from the reservoir, which is supplied 

 from the Brandywine Creek, at a considerable dis- 

 tance. After the water was drawn off, we found 

 the following: Abr amis cry soleucas, JVotropis hud- 

 sonius amai'us, N. analostanus, JV. cornutus, Cypri- 

 nus carpio, Catostomus commersonii, Ameiurus neb- 

 ulosus, Lepomis auritus, Eupomotis gibbosus and 

 Boleosoma nigrum olmstedi. On September 24, 

 1910, we again inspected other of the filter-beds, 

 finding all of the above except Ameiurus nebulosus, 

 besides the following additional species : Anguilla 

 chrisypa, Semotilus bullaris, Ameiurus catus and 

 Micropterus dolomieu. On November 20 and 21, 

 1913, we again visited Wilmington, and examined 

 the reservoir after the water w f as drawn off. We 

 found it contained the following : Notrojiis analos- 

 tanus, Cyprinus carpio, Anguilla chrisypa, Lepomis 

 auritus, Eupomotis gibbosus and Micropterus salm- 

 oides. These lists are quite interesting as showing 

 the variety of species which gradually stock artifi-
