CLUPEINiE. THEIR ANALOGIES. 279 



fish brings us at once to Clupea, by that singular species, 

 the Clupea Sinensis of Bloch, which is a true herring, 

 having, however, the same broad form as P. Africana : 

 the ventral, although placed beneath the dorsal, is yet 

 very small, being only half the size of the pectoral ; 

 while the anal, although not so long as in that fish, is 

 yet longer than in any other example of the typical 

 Clupece. Here, then, all further distinction ceases, for 

 we actually return to the first type we began with : 

 the circle of the series is closed ; and we find Clupea, 

 Chatoessus, Th?*yssus, Pristogaster, and Platygaster so 

 closely and intimately blending into each other, that we 

 scarcely can say where one begins, or where the other 

 ends. 



(241.) Affinity, more especially when so strongly 

 manifested as in these instances, must always take place 

 of analogy. We have, therefore, laid before the naturalist 

 these details, before we premised any thing of the results 

 or inferences that may be drawn from them ; let him go 

 through the series himself, and then, if we are not greatly 

 deceived, he will be fully sensible of its representative 

 nature, and will hardly need the following confirmation 

 of it, drawn from the analogies which this group presents 

 to all the others we have given of this family : those, how- 

 ever, of the principal divisions of the Clupeincs are so con- 

 clusive, that we cannot refrain from drawing them up.
