In the Tribe Galatheidea the body is symmetrical, and more Table-case 
or less lobster-like, but the abdomen is bent upon itself, and No - 12 - 
sometimes folded under the body. The last pair of legs are 
slender and are carried folded up within the branchial chambers. 
The last pair of abdominal appendages (uropods) are large, 
forming a well-developed tail-fan.

Several species of Galathea occur on the British coasts, G. 
strigoscc being the largest. Municla rugosa (Fig. 42) is found in 
rather deep water in British seas. The family Uroptycliidae 
includes only deep-sea species and is represented by the brilliantly 
coloured Eumunida pictct. The family Aegleidae comprises only a 
single species, Acglea laevis, which is interesting as being the only 
Anomuran inhabiting fresh water. It is found in South America,
