A large trout, caught by Major Eccles in the Silverstream, was exhibited, and Dr. Hector, after examination, considered it was not a Californian salmon, but the same form of trout which is common in Otago, Canterbury, and Nelson, and that it is probably the progeny of the variety known as “Thames brown trout,” which were first introduced into Tasmania, and thence distributed to New Zealand. The fish caught in the Silverstream was a female, with the roe just commencing to develope, and its stomach contained food of fresh-water origin. At first sight it appeared to be very similar to the Californian salmon.
