MacrocypHs metadata, G. S. Brady- — 



This species has a wide distribution, occurring in Bass Strait, 

 round the Southern Ocean at Kerguelen Island, off South 

 Africa, and in the West Indies. It is typical of moderately 

 shallow water. M. maculata is distinguished from the common 

 Australian form of the genus, M. decora, by its less arcuate 

 carapace as seen from the side, and less pointed extremities. 



Ostracoda from Shore-Sand, Williamstown.

Bairdia amygdaloides, G. S. Brady. — 



This specimen is a young form, and is less regularly ovate 

 than in the adult. The Challenger examples came from Bass 

 Strait (East Moncceur Island) and Port Jackson, amongst 

 other localities. This species seems confined to the South 

 Pacific and the Southern Ocean. It is a remarkable fact that 

 B. amygdaloides was well established in the Southern Hemi- 

 sphere in Miocene times, being Found in the Janjukian of the 

 Malice, and there ranging into beds of later age.
