CLUPEIDE. 



The lower jaw the longest and smooth ; the upper jaw 

 with a central notch ; the lateral edges crenated : the breadth 

 of the eye rather less than one-fifth of the length of the 

 head, and placed one diameter and a half from the end of 

 the nose : mucous vessels of the gill-covers beautifully dis- 

 tributed ; the nape and shoulders rise suddenly ; the greatest 

 depth of the body just before the ventral fin ; scales of the 

 body rather large, nearly circular, and thin ; no distinct 

 lateral line ; abdominal edge strongly serrated, particularly 

 behind the ventral fins. The colours very similar to those 

 of the Twaite Shad, with a single dusky patch behind the 

 operculum, sometimes scarcely visible. 



Figure 1 of plate III. in Dr. Fleming's Philosophy of 

 Zoology is a representation of the Allice Shad.
