Tuis 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 antenne 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.
