PISCES. 147 



dinav. Fislcar, PL 11, 23 ; in the North Sea : this fish seldom is more than 10" 

 long; there are four rays in the first dorsal fin, which in the male are very 

 long; in the second dorsal fin, which in the female (Call. Dracunculus) is 

 higher than the first, nine or ten are counted ; there are neither pyloric 

 appendages nor a swimming-bladder. In other species also of this genus 

 the sexual difference is great ; in Callionymus ocellafus PALL. Spicil. Zool. 

 vm. Tab. iv. figs, r 3, the female, unless PALLAS be mistaken, would 

 seem to have a higher first dorsal fin, with four ocelliform spots, which are 

 absent in the male.
