(1924). They are directed forward, are setose, and are used in feeding. The larva first begins eating 

 in this stage. The thoracic segments without limbs are distinct as narrow encircling wrinkles in the 

 integument. 



The abdomen is smooth and unsegmented. The telson has six, serrate, terminal spines decreasing 

 in size from the outer to the inner, three pairs of serrate, postero-lateral spines increasing in size from 

 the outer to the inner, and one pair of small ventro-lateral spines.
