appends a foot-note,* of which the following is a free translation : 

 Say's description is too incomplete to enable one to affirm, with 

 absolute certainty, that the following forms are synonymous ; 

 nevertheless it is highly probable that they are. This is invariably 

 the case with all the old descriptions of Ixodides. Say concluded 

 his description with the following remark : — " Found in consider- 

 able numbers on a Cerviis virginianus, in East Florida." 



It is interesting to note that Rhipicephalus annulatus, which 

 is responsible for the transmission of what is known in the United 

 States as " Texas Fever," is found in Texas, Maryland, Washing- 

 ton, Chicago, Baltimore, Kentucky, Kansas, Arkansas, New 

 Mexico, and Honduras, on cattle ; Cuba, cattle and dogs ; Jamaica, 

 cattle ; Florida, on deer (Cariacus virginiamis, Bodd.) ; Guada- 

 loupe, on cattle (where it is known as the " Creole Tick," in 

 opposition to the Hyalomma cegyptium, or " Senegalese Tick ") ; 

 it is also found in Guatemala, Mexico, and Monte Video ; it 

 occurs in Paraguay, where it has been found ensconced under 

 bark of trees, and it has been taken in Timor on the " Sambar " 

 deer ( Rusa equinus, Cuvier) ; the cattle of the Caucasus and 

 Traiiscaucasus, of Asia, and of Singapore, are also affected by it; 

 the pest is also known in North and South Africa ; in Algiers 

 and at Morocco, on African cattle, Barbary and Touarick sheep ; 

 again, it occurs in Egypt, Madagascar, at Cape Lopez, Gaboon, and 

 Port Elizabeth (South Africa). It may, therefore be considered, 

 as Neumann observes, cosmopolitan. 



The reviser also described a variety from the typical form, 

 under the name oi RhijAcejiJialus annulatus caudatus; but I would 

 advise those interested in the study of these creatures, to peruse 

 Professor Neumann's work, from which the notes necessary for 

 this brief contribution were made.f 



It is evident, from the foregoing, that the danger of the 

 pest spreading is even greater than some of our Australian 

 authorities and experts may have imagined. It is only fair, 

 however, to state that Mr. C. J. Pound, Bacterioligist to 

 the Queensland Government, has, in a recent paper, drawn 

 attention to the means by which Cattle Ticks may be spread. 

 He says| : — " (Jareful and close observations have shown that 

 although the bovine is the only perfect natural host of the 

 Cattle Tick, it is only one of the many agencies for its dis- 

 tribution. It has been proved that the tick will mature, under 

 favourable conditions, upon the horse and the sheep, and that the 

 eggs from such ticks are fertile. I have also found them in 

 various stages of development attached to goats, kangaroos, 

 wallabies, and various kinds of birds, as the ibis, crane, peewit.
