 7 in head in middle of its length; caudal subtrnncate with salient angles; 

 snout rather pointed ; nostrils close together ; no posterior cnnines; cheek 

 with 4 rows of scales. Teeth whitish ; general color violaceous ; sides with 

 a broad whitish band ; fins plain reddish, the upj)er violaceous ; upper lip

 seems to differ only in the presence of posterior canines; their absence in 

 the types of acutiis may be due to individual variations, (acutits, sharp- 

 pointed.)
