The greater number of resemblances are with Leuciscus lineatus. 



It is quite probable that the very fine rays of the pectorals have 

 failed to make an impression, which would account for the lesser 

 number of rays in turneri as compared with others. 



Epineurals, epiha^mals, and epicentrals are present, but there are 

 no apparent traced of epipleurals, nor should there be if the affinities 

 of this fish are as they have been assumed. 



The extreme length of the type specimen, which is of the average 

 size, from tip of nose to center of caudal, is 5^ inches; from tip of 

 nose to process of last vertebra, 4i inches. 



With the exception of a few small fragments it is the impressions 

 of bones that are preserved and not the bones themselves, and this fish 

 is placed with the CyjyrinidcB on account of its strong general resem- 

 blance to that group of fishes, since the pharyngeal teeth have not in 

 any case been found. For the same reason it is kept in the genus 

 Leuciseiis, as no sufficiently good characters can be assigned to these 

 specimens to warrant the establishment of a new genus.
