SHIRAS EXPEDITIONS TO WHITEFISH POINT. 147 



lakes. All of the specimens in the east lakes were small, however. 

 Many occurred in the beach ponds of the Mason's Creek region, and 

 some were found in a small shallow bay at the north end of Little Lake. 

 A hundred or more specimens were taken, which were 1 to 3.4 inches 

 long. In color a typical large one was light yellowish-olive above and 

 yellowish-white below, with a whitish streak along each side of the body, 

 and below this a grayish line, and then a jet black stripe. The sides 

 in a few specimens were tinged with pink, which brightened anteriorly. 

 This species resembles the red-bellied dace but differs from it in having 

 a more robust form, a larger and more oblique mouth, and a single, 

 not double, black lateral stripe. 



14. Ahramis chrysoleucas (Mitchill). Golden Shiner. — Small golden 

 shiners (1 to 1.3 inches long) were found in Mitten and in Wetherhog 

 Lake, but none were taken elsewhere. 



15. Notropis cayuga Meek. Cajmga Minnow. — Cayuga mimiows 

 were common and verj- generally distributed in the Whitefish Point 

 region. They were common in the upper beach ponds west of Ver- 

 milion, in the west group of marsh lakes, and in Shelldrake Lake. A 

 few were caught in Shelldrake River, and many were taken in the east 

 marsh lakes, but these were small in size, not over 1.5 inches long, 

 while most of the individuals caught in the west group (Beaver Lake 

 and others) were about 2.5 inches long. The largest numbers were 

 found at Station 55, where they belonged to the red-bellied dace asso- 

 ciation. There is a tendency in most regions, however, for Cayuga 

 minnows to school by themselves. 



Two large examples caught at Station 55 had been eating entomos- 

 tracans, insects, and diatoms. 



16. Notropis hudsonius (DeWitt Clinton). Spot-tailed Minnow. — 

 The minnow appears uncommon in the region, except possibly in Shell- 

 drake Lake. Six were obtained from Lake Superior close to shore in 

 two feet or less of water; ih&y were small, an inch or less in length, ex- 

 cept one, which was a fine large specimen 3.5 inches long. This large 

 specimen answers more closely to the description of tyjiical A"", hud- 

 sonius than it does to A^. hudsonius selenc, which is considered to be the 

 typical Lake Superior form. The other fish were too small for sub- 

 species determination. The only other place where spot-tailed minnows 

 were found in the region was Shelldrake Lake, where many little ones, 

 less than an inch long were found in the collections made along its 

 northwest shore (Station 142. Plate XXVB). 



17. Rhinichthys cataradae (Cuvier and Valenciennes). T^ong-nosed 

 Dace. — This fish was found in one xevy restricted region, — a deep area 

 under the pier in Vermilion Creek, and close to Lake Superior. Twelve 

 large ones (3 inches long on the average) were caught here (Plate
