Fig. 1, Nephrops Norvegicus. 2, Palpus pediformis. 
The colour of the N. Norvegicus is a pale flesh-red, occasionally varied with darker colour 
or with whitish. The grooves of the fore claws, and back of the abdomen are pale fulvous or 
cinereous. Eyes blackish. 
Sometimes the left anterior leg, and at other times the right is largest ; the internal edge 
of the fingers of the larger leg’ being knotted ; of the smaller one denticulated. 
In the summer months this species is very abundant, in the Frith of Forth, and is taken ad- 
hering to the bait of the fishermen who are employed in taking fish with lines. 
Fabricius, and all succeeding authors, describe this species as having but four didactyle 
legs, which renders their synonyms extremely doubtful : I have, therefore, refrained from 
quoting them.
