Trypanoplasma is especially abundant in association with a parasitic 

 Trematode, Lecithochiriian ruforiride, Rudolphi. 



No trace of the j)arasite has up to the present been found in any 

 other part of the intestine or rectum, or in the blood •^. The reaction of 

 the stomach wall in the fasting conger was found to be slightly alkaline, 

 though whether in the case of the conger there are periodical short 

 secretions of stomach juice, corresponding to those found in fasting 

 dogs, is a question that cannot well be answered. In a stomach film 

 mounted in the stomach juice and kept at room temperature after a 

 period of 20 hours some of the Trijpaìioplasìna became motionless, 

 assuming the head to tail position, and after rounding off became 

 disintegrated. During this period (some slightly active Trypanoplasmas

can be found on the slide after 88 hours] an increasing number of highly 

 aberrant forms make their appearance. These forms which never be- 

 come very numerous are roughly half the size of the smallest normal 

 Trìjpanoplasììia^ but they are provided with an enormously long anterior 

 llagellum. 



If the film from the stomach is mounted in a drop of the intestinal 

 fuice the Tnjpauoplasiuas immediately become united at first in pairs 

 and then in groups and disappear entirely at the end of about two hours. 



We propose , during the ensuing summer to try and work out the 

 life cycle of this form, and, if possible, arrive at some idea as to the 

 peculiar physiological condition of the stomach of the host which seems 

 to be associated with the presence of this parasite.
