THE GILT-HEAD. 497 



62'' lat. It is said to inliahit the more southern portion of 

 the Baltic. Its usual length is from eight to nine inches, 

 but it has been known to attain as much as ten. Kroyer 

 mentions having found females with mature roe at the 

 beginning of July, and on the 5th of that month he 

 examined a male witli JJijdende (all but fluid) luilt ; 

 consequently, he looks upon it as certain that this fish 

 spawns in July. 



Speaking of the bi*eeding habits of this fish, the 

 ProTessor says : — " It has been related to me by an 

 altogether trustworthy person, a distinguished savant, 

 and one who, though not a professed zoologist, is greatly 

 interested in the Northern fauna, that on a summer's 

 day about noon, and whilst standing on a low bridge, 

 looking down into the clear water beneath, his attention 

 was attracted bv two of these small Wrasses, which

 weeds. This, however, was for but a little time, when 

 they again appeared, and the like ceremony was once more 

 gone through, From what my informant relates — and 

 he and others watched their proceedings for upwards of 

 an hour — it appears to me that when these fishes were 

 close together, they wei*e in the act of pairing, and that 

 the fructification of the ova of the female then took place, 

 which is the more likely from what we know of the organs 

 of generation of both sexes. It also strikes me as more
