"I advise you to take excellent care of that specimen; for when it is gone, you never will get another. The species soon will be extinct." This opinion has been supported, quite independently, by a lady who is the highest authority on the present status of that species, Mrs. Mary G. Roberts, of Hobart, Tasmania. For nearly ten years Mrs. Roberts has been procuring all the living specimens of the thylacine that money could buy, and attempting to breed them at her private zoo. She states that the mountain home of this animal is now occupied by flocks of sheep, and because of the fact that the "Tasmanian wolves" raid the flocks and kill lambs, the sheep-owners and herders are systematically poisoning the thylacines as fast as possible. Inasmuch as the species is limited to Tasmania, Mrs. Roberts and others fear that the sheepmen will totally exterminate the remnant at an early date. This animal is the largest and also the most interesting carnivorous marsupial of Australia, and its untimely end will be a cause for sincere regret.

In 1885, when the National Museum came into possession of one poorly-mounted skin, from Professor Poey, of Havana, it was regarded as a great _prize_. Most unexpectedly, in 1886 American zoologists were startled by the discovery of a small herd on the Triangle Islands, in the Caribbean Sea, near Yucatan, by Mr. Henry L. Ward, now director of the Milwaukee Public Museum, and Professor Ferrari, of the National Museum of Mexico. They found about twenty specimens, and collected only a sufficient number to establish the true character of the species. Since that time, four living specimens have been captured, and sent to the New York Aquarium, where they lived for satisfactory periods. The indoor life and atmosphere did not seem to injure the natural vitality of the animals. In fact, I think they were far more lively in the Aquarium than were the sluggish creatures that Mr. Ward saw on the Triangle reefs, and described in his report of the expedition. It is quite possible that there are yet alive a few specimens of this odd species; but the Damocletian sword of destruction hangs over them suspended by a fine hair, and it is to be expected that in the future some roving sea adventurer will pounce upon the Remnant, and wipe it out of existence for whatever reason may to him seem good.
