inhabit Alpine waters in remote parts of the globe the environment 

 which has caused this convergence is limited to the conditions obtaining 

 in Alpine waters. A closer definition of the acting cause in the reduction 

 of the ventrals I am unable to give. 



In the last two instances I have but given facts which have forced them- 

 selves on my notice. The conditions obtaining on the Pacific slope were 

 determined after a careful comparison of all Pacific and Atlantic slope 

 species and the details of this comparison will appear in the publications 

 of the U. S. Fish Commission. 



On the fishes of "Wabash county. By A B. Ulrey. 



The present paper is presented as a contribution to the biological survey 

 of Indiana. It is apparent that before any complete survey of the fauna 

 and flora of the state can be made there must be a large number of local 

 lists of animals and plants representing the different regions of the state. 

 While the county forms in no sense a faunal area, there are numerous ob- 

 vious reasons for making county lists. It is perhaps not essential that 

 these local lists should cover faunal areas. When sufficient data are at 

 hand the matter can then be placed in sytematic order. 



Wabash county is situated in the northern third of the state a little east 

 of a line passing through the centre north and south. The Wabash river, 

 flowing a little south of west, passes through the county near its centre. 

 Eel river flows across the northwestern part and the Mississinewa crosses 

 the southwest corner, both of which finally reach the Wabash. 



The list here presented contains most of the fishes that occur in consid- 

 erable abundance in the county and some that are found only occasionally. 

 It is desired that it may be completed by some one in this region and 

 notes made on the spawning, life-habits and environment, presenting a 

 complete record of the ichthyology of the county. 



The collections here represented are a part of more extended collections 

 in other groups of animals and several groups of plants made by different 

 members of the AV abash County Science Club.* A series of the fishes of 

 the following list has been placed in the museum of Indiana University, 

 one in the museum of North Manchester College and another in the pri- 



This material is in preparation for the biological survey of the state.
