 as long as the body of the animal. A great develop- 

 ment of spines also 

 characterizes the larva 

 of Munida (Fig. 27). 



The larval form of 

 the Common Lobster 

 has already been, de- 

 scribed, and it will be 

 noticed that the dif- 

 ferences from the 

 adult are much less 

 than in the case of 

 the Crab. From the 

 fact that this larva 

 has swimming exopo-

 and Euphausiacea

be in the " schizopod stage." The larva of the 

 Norway Lobster (Nephrops norvegicus) is essentially 

 of the same type, but the great development of the 

 spines on the abdomen and of the forked telson 

 gives it a -striking appearance. 



A very remarkable type of larva is found among 

 the Spiny Lobsters and their allies (Scyllaridea).
