those who recognise it as a toothsome morsel rather than an 
object of Natural History. 
It is quite common to hear of the distinction ‘‘ Brown 
Shrimp ’”’ and “‘ Red Shrimp,” the preference being generally in 
favour of the former. Now the ‘‘Brown Shrimp” is our 
Crangon vulgaris, which in boiling never turns to the bright 
coral-red assumed by the Prawns when similarly treated. The 
‘*Red Shrimp,” on the other hand, includes several species, and 
even a few genera. For example, on the Thames steamboats 
the “Red Shrimp” is Pandalus annulicornis ; in Jersey I have 
seen Nika edulis sold under the same name. In Southampton 
I saw Palemon squilla (the small Prawn) similarly hawked about; 
and P. varians has occupied a similar position in places where it 
occurs in sufficient abundance to be of any marketable value. 
In his work on the Stalk-eyed Crustacea, I notice that Bell 
refers to this general term “‘Shrimp”’: he states that the 
smaller Palemonide are called “‘ Rock Shrimps,” to distinguish 
them from Crangon, or the ‘‘Sand Shrimp.” He also records 
that at Youghal the ‘‘ Gray Shrimp,” as Crangon is there called, 
is not much esteemed, but that the true Prawn, Palemon 
serratus, is thought a great deal of, and is called the “‘ Shrimp.” 
I will now give a short description of the species under 
observation. The carapace is full for so small an animal, 
flattened at the cephalo-thorax, or head portion, and narrowing 
off rapidly at the last two segments of the abdomen. The 
antenne are long, and protected by a fringed scale at their base. 
The first pair of legs are the largest, and possess each a movable 
finger or terminal joint, capable of closing on to the upper edge 
of the main joint, affording a firm hold for the animal; the 
remaining legs are simple. The abdominal legs or swimmerets 
are rather long and slightly plumose; the ova are attached to 
the base of these, as in the case of other crustaceans. The ova 
themselves are slightly oval in form, and are exuded about the 
early part of the year. The tail consists of a central plate 
shaped like a spine, with two fringed rounded edge-plates on 
either side. 
The colour of this species is grey or brownish grey, speckled 
with darker cells of pigment, but of course, like many crustaceans, 
this colour varies according to the habitat of the specimens ; for 
those from a light sandy bottom are paler and slightly yellow,
