a current off Cape Saunders setting in a northerly direction at 

 a rate of from one to one and a half knots an hour. The cap- 

 tains of the trawlers and the line-fishermen affirm the accuracy 

 of this statement, the latter stating that at times it is so strong 

 as to prevent them from fishing, as they are unable to get their 

 lines to the bottom. These currents must have considerable 

 influence on the migration and food-supply of our sea-fishes, and 

 in order to acquire a fuller knowledge of their spawning habits 

 and grounds it is necessary to take this into consideration. For 

 instance, identified pelagic fish-eggs of a known age — say, fifth 

 day — taken in the tow-net off Otago Heads, with a current of 

 two knots an hour setting to the northward, would have been 

 shed about two hundred and forty miles south of the place at 

 which they were taken. 



List of Fishes ivhieh have been taken in Otago Harbour or in 

 the Immediate Proximity. 



1. Polyprion prognathus, Forster. The groper occurs outside 



the Heads all the year round, and occasionally comes 

 into the harbour, keeping to the deeper parts. 



2. Arripis trutta, Cuvier. The kahawai is an occasional sum- 



mer visitor. 



3. Pagrosomus auratus, Forster. The snapper is another 



occasional visitor, and also appears to come only in 

 the summer months. 



4. Haplodactylus meandratus, Solander. The granite trout 



is not infrequently met with in the harbour. 



5. Chilodactylus macropterus, Forster. Recorded in Trans. 



N.Z. Inst., vol. xi, p. 381. 



6. Latris ciliaris, Forster. The moki occurs all the year round, 



and is a common fish near the rocks, and especially among 

 . kelp. 



7. Latris lineata, Forster. The trumpeter is not so common 



as it used to be. It is still met with at intervals, but 

 used to occur in all the deeper channels, near rocks. 



8. Latris cerosa, Hutton. The type of the species was taken 



at Otago Heads, and is in the Otago Museum. r 



9. Congiopodus leucopcecilus, Richardson.) One' of the com-
