DISCOVERY REPORTS 



Hab. Graham Land; Queen Mary Land; Adelie Land; South Victoria Land. 



This species was originally described from 3 specimens: i (132 mm. in total length) 

 from south-west of the Balleny Islands, 476 metres ; i (65 mm.) from Tent Island, 

 near Ross Island ; and i (about 65 mm.) from Seymour Island, collected in tide-pools. 

 It is closely related to T. hansoni, but may be distinguished from that species by the 

 smaller number of dorsal and anal rays, and by the presence (usually) of tubular scales 

 in the lower lateral line. Further, Waite has pointed out that in life this species is 

 reddish in colour, whereas T. hansoni is greenish or greyish. As a general rule, T. 

 loennbergii appears to live in deeper water than T. hansoni.

Hab. Queen Mary Land ; South Victoria Land. 



The types of the species, 5 specimens 100 to 140 mm. in total length, are from off 

 Cape Adare, 82 to 94 metres. Waite has recorded 10 specimens, up to 180 mm. in 

 length, from off Drygalski Island, 112 metres.
