Hybrids. 



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

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

 mediate between Clupea alosa and C. Jinta ; they are forty in num- 

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

 shorter than those of C. alosa. They are longer than the eye. 

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

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

 that this is a hybrid between the two species mentioned. 



a. Nineteen inches long. Old Collection. 



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

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

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

 hybrid between CI. pilchardus and CI. Jinta or alosa. It has the 

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

 latter ; unfortunately the gill-rakers arc not preserved, so that I 

 cannot decide whether the other parent was C. Jinta or alosa.

 sadina (Trans. Lit. & Phil. Soc. New York, i. p. 457) was evi- 

 dently a diflerent fish, which, however, cannot be determined at 

 present.
