THIS species differs from D. spinosissima, on which 

 Kroyer founded the genus, in the following particulars : 

 The head is not produced forwards into a sharp 

 rostrum ; the body and tail are smooth, being free from 

 teeth or spines. The eyes are round, but not raised upon 

 a stout tubercle. The superior antennae are about half 

 the length of the extended animal. The first joint of 

 the peduncle is short and robust, but the two succeeding 

 are long and slender. The flagellum (probably) is about 

 half the length of the last joint of the peduncle.
