mens show the lateral line incomplete, even skipping one or two 

 scales, or the break may be simply due to the irregularity of the 

 scalo rows, we have not seen the descent exactly as Bleeker shows. 

 We find, however, that sometimes an irregular lateral line may occur 

 on one side of the body and on the other form an even continuous 

 curve. Most all preserved specimens show a dark median area on 

 each caudal lobe, possibly a good character of distinction. The rows 

 of scales on the cheek are certainly variable. They are usually in 

 two rows, though may even vary to the condition found in Jordan 

 and Seale's figure of Priopis lungi, while more or less evenly biserial 

 on the other cheek. Now the figure by Day of Ambassis urotaenia 

 shows the scales on the cheek very large and in a single row. Many 

 examples we find have the front half of the cheek with a single row 

 of large deep scales and the posterior half biserial, or made up of 

 narrower scales. We also unite Ambassis miops Gunther and Ambas- 

 sis lafa Jordan and Seale as synonyms.
