02 Mr, Montagu's Description of several Marine Animals 



as in the preceding species : eyes pedunculated : arms and legs 

 scarcely definable, the anterior pair is terminated by a quadrifid 

 joint, expressed at fig. 4. a ; the second pair is cheleform, as at b ; 

 the other three pair appear, when magnified, to have a toothed 

 claw, represented at c: besides these there are two very long and 

 slender appendages, that do not strictly appear to be legs, but 

 seem to be auxiliary to the palpi, though they originate so far 

 from the mouth, for they are always placed forward towards the 

 mouth ; these are slightly chelate : the caudal fins are similar to 

 those of the prawn, with a small spine near the end of the ex- 

 terior pair, as at d. 



What at once distinguishes this from the young prawn, or from 

 any other, is the protuberant and curved formation of the third 

 joint of the body, at which part the posterior end, or what is 

 usually termed the tail, makes a short turn when doubled under 

 the body. 



The colour when alive is red. 



Length rarely above an inch. 



Not unfrequently taken by dredging at Torcross..
