Besides the Amoeba already noticed in Asdepiadaceae under glass 

 in Paris {R.A.E., B, x, 145] Amoeba chlorocodonis, sp. n., has been 

 discovered in the latex of Chlorocodon whitei. No experiments regarding 

 its pathogenicity to animals have yet been made, but it does not 

 phagocytise the red blood corpuscles.

Hitherto there has been no mention of true flagellates in the latex 

 of Urticaceae. A flagellate closely allied to Herpetomonas, which is- 

 here described, was found in the fruit of an exotic species, Ficus. 

 parietalis, in the hot-houses of the Paris Museum. The same plant 

 harbours Herpetomonas, Crithidia and trypanosomes, and it should 

 be remembered that some insects can harbour all three of these parasites, 

 in their digestive tubes. In the fruit-tissues the parasite increases 

 rapidly, having the appearance of leishmaniform parasites and minute 

 trypanosomes.

This note describes experiments in which mice were naturally infected 

 by a flagellate, Herpetomonas {Leptomonas) ctenopsyllae, occurring in 

 fleas, Ctenopsylla musculi, Dug., living on the mice. Although the fatal 

 pathogenic character of the infection is probable, the parasite being 

 found in the internal organs, the rapid death of the mice must have been 

 caused by exhaustion due to the fleas, because infected mice sheltered 

 from fleas lived for several months. The question is justified, whether 

 in nature there exists a normal cycle of H. ctenopsyllae from mouse 

 to flea.

The bodies of the dead mice from the breeding cages of Ctenopsylla 

 musculi. Dug., infected with Herpetomonas {Leptomonas) ctenopsyllae 

 [see preceding paper] were covered with the dried excreta of the fleas. 

 A solution of the excreta was inoculated into a mouse ; and leish- 

 maniform parasites were afterwards found in its blood and internal 

 organs.

In reference to Franchini's note [R.A.E., B, x, 145] the author 

 reviews the facts as at present established. 



Latex plants can harbour in the latex flagellate protozoa of different 

 species, which have Rhynchota as primary hosts. For example,.
