Ammothea meridionalis. 
Body short with lateral processes close together and lightly tuber-

Body discoid, smooth. Abdomen very long and cephalon broad. 
Ocular tubercle stout erect with well developed eyes. 
Winter Quarters. 
Austrothea. 
A new genus designed for those Ammotheid species whose body is 
not discoid in any sense of the term and is without the transverse ridges 
so characteristic of Ammothea in its new signification, also the com- 
paratively long legs is a further character of importance. 
Austrothea spicata. 
Body stout, divergent lateral processes, the proboscis ovate, slender, 
and the abdomen nearly as long. Ocular tubercle tall, terminating in 
a long spike. 
8. IL. 1903. 350m. A single specimen only. 
Austrothea germanica. 
Insignificant spurs on the lateral processes and more conspicuous 
ones on the first coxae. Ocular tubercle elongate, pointed and directed 
forwards.
