11, Barracouta {Thyrsites atun). 



Number of Fish recorded. — 39. 



Localities. — Mokohinou, Portland Island, French Pass, 

 Moeraki, Cape Saunders, Dog Island, Bligh Sound, Milford 

 Sound. 



Dates. — January to October. 



Weight. — Average, 51b. ; largest recorded, 81b. 



Food. — In every case but one the stomachs contained small 

 fish (herrings, sprats, mullet, trevally, &c.). One opened at 

 Dog Island contained shellfish and crabs. 



Reproduction. — The record is unsatisfactory. One fish 

 taken at Mokohinou in September was said to contain 

 "ripe" ova, and others taken in January in Milford Sound 

 were also ripe. The late Captain Hayward, of Catlin's 

 Eiver, was of opinion that this species spawned twice a 

 year, but I do not know on what data his conclusions 

 were based. 



12. Horse-mackerel {Trachurus trachurus). 



Number of Fish recorded. — 49 (examined), but immense 

 numbers stranded on the beaches. 



Locality .—Miliovdi Sound. 



Date. — November to January, but seen in the sound for 

 the greater part of the year. 



Weight. — Average, 21b. ; largest, 41b. 



Food. — In nearly every instance the stomachs contained 

 pilchards, and it was in pursuit of these fish that the horse- 

 mackerel got ashore in such numbers. Some caught in No- 

 vember contained shellfish. 



Beproduction. — Some of the large fish taken in January 

 contained " ripe " ova. 



13. Trevally {Caranx georgianus). 



Number of Fish recorded. — 60. 



Localities. — Cape Maria van Diemen, Mokohinou, Port- 

 land Island, Puysegur Point. 



Dates. — All the months except March, May, June, and 

 July. 



Weight. — Average, 31b. ; largest recorded, 61b., at Cape 

 Maria. 



Food. — Crustacea (crayfish, crabs, whale -feed, and 

 shrimps), small fish, shellfish (chiefly mussels), and in one 

 instance squids. 



■ Beproduction. — One entry under this head gives "Full of 

 roe " in November. Two others give " No ova " and " Un- 

 ripe " in October and December respectively.
