A variety of species are sold in England under the 

 name of Prawns. The largest of the native species, 

 to which the name of Common Prawn is perhaps 

 most properly restricted, is Leander serratus. It 

 grows to a length of over 4 inches, and has a long 

 serrated rostrum extending beyond the antennal 

 scales and curving upwards at the point. The first 

 and second pairs of legs end in small pincer-claws. 

 When alive the animal is very transparent, and 

 beautifully marked with bands of brown and red on 

 the body and limbs. A smaller species of the same 

 genus (L. squilla), distinguished by the much shorter 

 and straighter rostrum, and another very similar 

 species of which the proper name appears to be 

 L. adspersus (often known as L. fabricii), are said to 

 be sold on some parts of the English coast as " Cup 

 Shrimps." 



Much commoner, at least in the London market, 

 than the species of Leander is Pandalus montagui, 

 often sold under the general name of Prawn, but 

 sometimes called the " Pink Shrimp." This re- 

 sembles Leander serratus in having a long, serrated, 

 up-curved rostrum, but differs from it strikingly in 

 the form of the anterior pairs of feet. The first pair 

 appear to the naked eye to have no pincer-claws, but 

 to end in a sharp point, resembling the third maxilli- 

 peds, which are just in front of them. As a matter of
