PLANARIAN. 



Land Planarian ; " Flatworm." Bipalhim kewense. 



BiPALiDM KEWENSE. — 1, extended ; 2, contracted ; 3, 4, aud5, ditt'ereut forms taken 

 by the head, all life size ; G, bifid form of head, rather larger than life.* 



The worm-like creature, with its various forms of head, figured 

 above, scientifically known as a "Ground Planarian," is not noticed 

 on account of any injury which it causes, of which I have no notes, 

 nor do I find mention of it causing, in such publications as I am 

 acquainted with as to its history. But, as among the rare notices of 

 observation of this " exotic worm " in this country, it is mentioned as 

 found in a greenhouse, in hothouses, also amongst broken tiles at the 

 bottom of a pot of Calceolaria which had been in a cold frame all 

 winter, and also amongst broken flower-pots, it seemed to me that a 

 few notes on the subject might be acceptable to some who may be as 

 unacquainted with this repulsive almost poisonous-looking "Flatworm " 

 as I was myself, on as pecimen being sent me for examination in May 

 of the past season. 



* The above figures 1-5 are from the plate accompanying the "Note of Bipa- 

 Hum ketvense, and the generic characters of Land Planarians," by Prof. F. Jeffrey 

 Bell, M.A., Sec. R. M.S., in 'Proceedings' of the Zoological Society of London 

 1886, pt. ii. pp. 166-1G8. Figures 1-5 are copied, excepting in respect of the 

 position of figure 1 being altered to adapt it to space. Figure 6 is from my own 

 specimen, somewhat enlarged.
