SHRIMPS AND PRAWNS. 171 



a street-door ; the latter to keep enemies and prying intruders 

 out of her burrow. Her majesty measures about two inches 

 in length, and her crust is very thin and parchmenty. 



That was a day to be remembered by Colonel Montagu, for 

 on the same occasion he unearthed another burrower 

 Upogebia stellata new to science. This is more lobster-like 

 than Callianassa in form, though less so in size, for it is only 

 about an inch and a half in length. It is content with having 

 pincers to the first pair of legs, and these are nearly equal in 

 size. All the limbs are liberally fringed with long hairs. The 

 carapace begins with a small and sharp rostrum. Dr. Leach 

 records it from mud in Plymouth Sound. Its colour is 

 yellowish-white, sprinkled with minute orange spots. 



And now, though we have by no means exhausted the list of 

 British species, we must close this chapter. It should be 

 stated that all thsse creatures go through a series of transfor- 

 mations similar to, but not identical with, those marking the 

 early life of the crab and lobster.
