Hybrids. 



There is a very singular example in the British Museum, which, 

 as regards the development of the gill-rakers, is perfectly inter- 

 mediate between Chtpea alosa and G.finta; they are forty in num- 

 ber, not very closely set, and longer than those of C. finta, but 

 shorter than tbose of C. alosa. They arc longer than the eye. 

 There is no other character wbich would indicate that this is a dis- 

 tinct species: D. 21. A. 25. L. lat. 68. L. trans v. 22. I believe 

 tbat this is a hybrid between the two species mentioned. 

 a. Nineteen inches long. Old Collectio]i. 



By the kindness of Mr. Couch I have been enabled to examine 

 the typical example (or rather the remains) of his Alosa sqiiamo- 

 pinnata (Fish. Brit. Isl. iv. p. 123, pi. 206). This is evidently a 

 hybrid between CI. pilcliavdm and Gl. finta or alosa. It has the 

 large scales of the former, and the ventral fins placed as in the 

 latter ; unfortunately the giU-rakers are not preserved, so tliat I 

 cannot decide whether the other parent was 0. finta or alosa.

 present.
