194 Transactions.— Zoology. 
enough, a gentleman happened to be in Christchurch who had been engaged 
for years on “Canneries” on the west coast of America. He was shown 
the fish in Dr. Campbell’s surgery, and identified them as Californian 
salmon. This, however, is scarcely proof of identity of species or genus. 
But from a description and drawing (fig. 1, one-fourth nat. size) of part of the 
8lb. fish sent me through Dr. Campbell, I have bad no difficulty in recog- 
nizing it as of the genus Oncorhynchus, the distinguishing feature in which 
is the possession of more than 14 rays in the anal fin (Giinther); but 
there are not enough data in my possession to determine the species. The 
Salmo quinnat is the species said to have come here, and it is of the genus 
Oncorhynchus, quite a distinct fish from the Salmo salar. The fin rays in 
this specimen (which has been preserved) are these :— 
D.13—P.16—V.9—A.15—C.19.

Coregonus albus (American whitefish).—In February, 1878, 20,000 ove 
of this fish were received from San Francisco through the New Zealand 
Government, whereof 12 hatched out, and 8 survived, which were placed in 
a tributary of Lake Coleridge by Sir J. Cracroft Wilson. Very much 
better results attended the next experiment in January, 1880, when 
500,000 ova, less bad ones, were placed in ‘the hatching boxes at Christ- 
church, immediately on their being landed from San Francisco, January 
17th. Hatching began on the 20th, and ended on the 29th, the temperature, 
by means of ice in the water, being kept at 54°. The number hatched out 
was estimated at 50,000, but great numbers died from fungoid disease. 
These were removed daily until February 24th, when about 25,000 re- 
mained. The race water used averaged 56° Fahr. On February 24th, these 
fish, by the society’s admirable arrangements, and under the care of the 
Messrs. Farr and Sir Cracroft Wilson, were successfully conveyed from 
Christchurch by rail and buggy to Lake Coleridge in twelve hours, and
