228 R. T. LEWIS ON SOME AUSTRALIAN TICKS. 



Mr. Pound ; but inasmuch as Mr. FuUagar's drawing does not 

 very accurately represent this tick it has been thought desirable to 

 illustrate the present paper by figures enlarged from Mr. Pound's 

 specimens. Those who have the article in "Science Gossip" to 

 refer to will notice that the fig. 26 on p. 122 of vol. x. shows the 

 palpi as having three joints instead of four, and gives six joints 

 to each leg, whereas the first pair of legs have seven joints, and 

 the other three pairs have eight joints each, exclusive of the claws. 

 The claws are also erroneously drawn as being in one solid piece 

 with the terminal joint of the tarsus.
