Inner antennae ending in three many-jointed filaments. 
Second pair of legs stronger than the fore pair, and having

The species of this genus are much sought after and 
esteemed for their delicate flavour. When cooked they

Pal/emqn serratus, Pabr. Common Prawn . (Plate IX. 
fig. 2.) — Beak extending considerably beyond the lamellar 
appendage of the outer antennae ; much bent back near the 
end, and bifid at the tip ; the upper margin smooth on the 
front half, and armed on the posterior part with seven or 
eight teeth. 
A common species on most parts of our coast ; it is much 
sought after as a dainty. Mr. Couch remarks that the 
largest specimens are found on the rockiest coasts, where it 
seeks the shelter of large stones and places overhung with 
weeds. He adds that this species prefers the stillest waters, 
advancing and retiring with the tide; in summer it prefers 
water that has a distinct feeling of warmth, and in winter 
it seeks what is at that season less cold than at the margin,
