THE SPOTTED GUNNEL- 235 



captured off the pier-head at Leith. Their principal food 

 is small shells and young crabs; and I have also found their 

 stomachs distended with sea^weed. They spawn in the month 

 of June, and possess no swimming-bladder. They are never 

 brouffht to market or used as food. 



All the British species of Blennius, excepting the pre- 

 sent one, are furnished with one or more appendages placed 

 on the head in the region of the orbits. 



Genus MUB^NOIDES— Body elongated, sword- 

 shaped, with a single dorsal fin composed of short stout rays ; 

 ventral fins placed before the pectorals, reduced nearly to 

 a single ray ; teeth on the vomer, and in two rows in each 

 jaw; dorsal and caudal fins continuous.
