BRITISH STALK-EYED CRUSTACEA. 149 



whence probably the name of the animal. The first pair of 

 legs are short, with small rounded claws. The length is about 

 an inch to an inch and a half, and the colour, I believe, similar 

 to a shrimp, but variable ; those I have seen being only dead 

 specimens. 



It is stated by Bell to be exclusively a northern species, but I 

 obtained all my specimens from off Harwich, where they were 

 taken in shrimp-nets. Milne-Edwards says it is found in the 

 seas of Iceland and Greenland. It has also been recorded from 

 the Isle of Man (deep water), St. Andrews (deep water), and 

 the Firth of Forth.

This species has, I believe, been removed to the genus 

 Caradina. It differs from the preceding by the absence of the 

 spine on the third segment, by a smooth carapace and slender 

 rostrum, and also in being smaller and much less robust in form. 

 It is undoubtedly one of the most beautiful of the smaller 

 crustaceans, and is often of a lovely transparent green tint, 

 which enables it to pass almost unnoticed in the AlgaB-lined 

 rock-pools, where it lives ; it is quite common in our southern 

 and warmer localities, Jersey, of course, being a specially good 

 locality. It is also recorded from Devon and Cornwall, eastward 

 as far as Poole Harbour, Dorsetshire, as well as from the coasts 

 of Connemara and Dublin. 



According to Bell, it loses its lovely green colour soon after 

 death, but with careful preparation I find that it can be almost 

 entirely retained,

In this species the carapace is short and rounded, the rostrum 

 has three serrations, and the whole animal is shorter and 

 slightly more robust than the last mentioned. The central or 

 spine-plate of the tail is sharply spinous on either side. The 

 length of the animal is from half an inch to three-quarters of 

 an inch. 



It has been recorded by Bell from Torbay, Salcombe Bay, 

 Poole, and Loch Fyne; and has since been recorded from Ardbea 

 Bay, West Coast of Ireland, in four fathoms ; Dublin, not 

 uncommon ; Galway, common ; Belfast ; South Devon and 

 Harwich (in shrimp-nets).
