coast. All the specimens obtained were attributable to TJ. porosus, 

 although the very nearly allied U. signatus, Giinth., is usually 

 accounted the commoner species. This may be in part explained 

 by observing that whereas the former has a wide distribution, U. 

 signatus has not been recorded on the coast, other than from Port 

 Jackson and Botany Bay.

The only example obtained was a partially digested individual 

 ejected by a Dory as it iscy on deck. On the Mackerel being- 

 recognised a sharp look-out was kept for Mackerel shoals, but not 

 a living example was seen.

Stations 17, 27. 



Originally described from the coast of Chili, and known also 

 from Japanese, Indian and Australian Seas, yet the only recorded 

 Australian habitats are Port Phillip in Victoria, whence a single 

 example has so far been made known, and the Port Jackson dis- 

 trict in New South Wales, where it is quite common. Its known 

 range on our coast is now extended considerably northward. 



Station 17 is off Broughton Island, north of Port Stephens, 

 while Station 27 is much further north, off the Manning River, 

 and was the most northern point at which the ti-awl was lowered 

 Some of the specimens obtained were in spawn.
