by A. Marche. (Lucas states that this species attaches itself especially 

 to the sides of the belly near the anal and genital regions, and also on 

 the back); (b) 30 os, collected by Jules Verreaux in Tasmania in 1843 

 (Paris Museum). (Pagenstecher records several from Ornithorhynchus ; 

 he took them for females); (c) three %s, from the Ornithorhynchus 

 (Me'gnin coll.). Neumann (1901, p. 285) states that this tick has also 

 been found on the legs of Ornithorhynchus (coll. Bureau of Agriculture, 

 N. S. Wales). Our figures are drawn from Lucas' types and specimens 

 in the M^gnin collection (now in the Lab. de Parasitol., Paris).
