During the Percy Sladen Expedition to Brazil in 1913 

 Professor J. P. Hill collected six specimens of land leeches, 

 and while I was on leave from the Australian Imperial Force 

 in France, and acting as Demonstrator in his department, he 

 requested me to describe them. I was glad of this opportunity, 

 for these leeches, themselves earthworm-like in appearance, 

 were easy to determine as close relatives of Lumbrico-

 copied the form and habit of an earthworm. 



I have determined these specimens as 



Centropygus joseensis (Grube et Oerstedt, 1859). 

 Pyn. C entropy go s joseensis (Grube et Oerstedt, 1859). 

 Centropygos jocensis (Grube et Oerstedt, 1859). 

 Cylicobdella lumbricoides (Grube, 1871). 

 Nephelis tergestina (E. Blanchard, 1892). 

 Liostomum joseense (Grube et Oerstedt, 1859; E. 

 Blanchard, 1896). 



In view of the want of any note (save Weber, 1914) on this 

 leech, made in its natural state, the following extract from 

 Professor Hill's diary is of value :
