THE QUEENSLAND CATTLE TICK — KAINBOW. 133 



wild duck, and even on the little shepherd's companion (wagtail)." 

 In addition to these hosts, Mr. Pound points out that "In studying 

 the habits of various species of ticks living apart from their host 

 under natural conditions on some of the northern rivers of this 

 Colony [Queensland], I have noticed that in the larval stage there 

 was a natural inclination or instinct to attach themselves to any 

 moving object, no matter whether animate or inanimate." 



The Governments of New South Wales and Queensland have, in 

 their wisdom, deliminated a boundary beyond which cattle from 

 affected areas must not pass without inspection and treatment, and 

 this, so far as it goes, is very right and proper. It has been urged 

 that the cattle tick cannot thrive on hosts other than bovines; but 

 even supposing so, the fact that living examples have, in different 

 parts of the world, been found upon deer, sheep, dogs, and even under 

 bark, is in itself sufficiently conclusive evidence as to a means by 

 which "Texas Fever" may be conveyed, and that, in order to be logical 

 and thorough, the quarantine regulations should be extended to 

 all animals travelling from the affected districts. It is a recognised 

 fact that the disease is slowly but surely spreading south — hence 

 the necessity of extending the proscribed area ; and it is only a 

 question of time, therefore, when it will have invaded New South 

 Wales, and who can tell where or when its devastating march 

 will stop 1 Stock owners of New South Wales and Victoria would 

 do well, therefore, to note the facts recorded by Professor 

 Neumann. 



OCCASIONAL NOTES. 



l.—STEGOSTOMA TIGRINUM, GMEL. 

 An addition to the FAUNA op NEW SOUTH WALES. 



On March 14th of the current year, we received from Mr. W. 

 Hibbs an example of the shark Stegostoma tigrinum, Gmel.,* 

 caught in the River Ilawkesbury, New South Wales. It is a 

 female, measures four feet in length, and in colour nearly agrees 

 with var. 3 of Miiller and Henle.f The observations were made 

 while the shark was still alive, it having been received by us in 

 that condition. The ground is creamy, with a greenish hue about 

 the head and dorsal region ; the markings are black spots, smaller 

 and regularly arranged on the head, much larger and more widely 

 spaced on the body and fins.
