GALATHEA. 87 



Galathea squamifera, Mont. sp. Montagus Plated 

 Lobster. — Beak short, wide, armed with nine spine-like teeth. 

 Front legs wide, flattened, spiny on the sides, and furnished 

 above with scale-like tubercles. Outer jaw-feet with the 

 third joint much longer than the second. Greenish-brown, 

 occasionally tinged with red. 



Under stones at low-water mark, south and west coast of 

 England, Irish coast, Firth of Forth. The Rev. Alfred 

 Norman found it at Cumbrae, in the Firth of Clyde. 



Galathea strigosa, Linn. sp. Common Plated Lobster. 

 (Plate VI. fig. 1.) — Beak triangular, aud armed with seven 

 strong, spine-like teeth. Front legs broad, very spiny, spined 

 on both edges. Outer jaw-feet with the third joint shorter 

 than the second. Red, with blue lines and spots. 



Found in deeper water than the last. Mr. Harris has 

 found it as far north as the Moray Firth, and Dr. Howden 

 takes it in deep water near the Bass, at the mouth of the 

 Firth of Forth. 



Mr. Couch remarks of this species, in his ' Cornish Fauna' 

 (p. 76), that it is "incapable of any motion but backward, 

 and rarely rises above the bottom, where, by a laborious 

 motion of its tail, it contrives to retreat from its enemies ; 

 but its usual progress is creeping, and by the legs only."
