26 THE FISHERIES OF THE ADRIATIC, 



(b) The Squatters? which are bound to given localities, and have their 



fixed abodes. 

 2. The Migratory or Pelagic class {voyageurs), which frequents the 

 deep, without reference to the coast or formation of the bed. 



Class I. — Sedentary Forms. 



i. Littoral forms in depths of 0-6 fathoms, or within the third and 

 fourth zones. . 



{a) Littoral Rovers. — On the open coast-lands most species of Blcnnies 

 and Gobies abound, such as the ocellated Blenny, or Butterfly-fish, a 

 British species here common ; Bl palmicomis, BL tentacularis, and Bl. pavo, 

 rarer ; the black Goby, a British species, common, and G. capito rarer. 

 These genera are numerously represented in these waters, the Gobies by no 

 less than twenty-two species, of which only seven are known in British 

 waters ; and the Blennies by fourteen species, of which four belong to the 

 British fauna. Some of them are brilliantly coloured. 



Calm and sheltered rocky shores are frequented by Lepadogasteres, or 

 Suck-fishes, amongst which are three British species : the Cornish Sucker 

 and the Connemara Sucker are the most prevalent of this genus. 



The Wrasses hover about the littoral tangles and grass-wrack ; they are 

 very numerous, and are represented by twenty distinct species, only four of 

 which are known in British waters. This is the characteristic genus of the 

 Mediterranean region. 



Amongst the most prevalent species are Labrus turdtis, L. mei'ula, 



Crenilahrus pavo, Cr. melops (the Cork wing), Cr. quinquemaculatus, Cr. 



griseus, Cr. rostratus, Con's Geoffrcdi, and Coris julis (the Rainbow Wrasse). 



They are very brilliant, and the last-named is the brightest of the painted 



beauties, exceeding all Adriatic fishes in splendour of colour. 



Shallow zostera fields, on clay or muddy beds, are the favourite resort of 

 the Atherines {Atherina kepsetus). 



1 I consider these divisions the most appropriate rendering of what Dr. Lorenz terms (a), 

 Grundschwartner ; (b), Grtmdstete.
