MASTIGOPHORA AND PROTOMONADINA 



Keysselitz is of the opinion that all so far described species should be con- 

 sidered to belong to one species — Trypanoplasma borreli L. and M. 

 Type Species. — Trypanoplasma borreli Laveran and Mesnil, 190 1 . 



Trypanoplasma borreli Laveran and Mesnil, 1901 . 

 In the blood of Leuciscus erythrophthalmus (the rudd) and Phoxinus Icsvis 

 (the minnow), and in the alimentary canal of the leech Pisciola geometra, and 

 perhaps in Hirudo medicinalis. 



Trypanoplasma cyprini Plehn, 1903. 

 In Cyprinus carpis. 



Trypanoplasma (Cryptobia) dendroe(Bii Fantham and Porter, 19 10. 

 This parasite measured 20 to 40 n in length, with a large and often curved 

 kineto nucleus. It lives in the alimentary canal of Dendroccelum lacteum, and 

 was the first trypanoplasma to be found in the Platyhelminthes. 



Trypanoplasma intestinalis Leger, 1905. 



This trypanoplasma is very important, because it was found in the oesophagus 

 and anterior part of the stomach oiBox hoops, a salt-water fish. 



It is the first trypanoplasma described as existing outside the blood. In 

 addition to t5^ical forms, Leger describes globular parasites with three anterior 

 flagella and a rudimentary undulating membrane, which reminds one of 

 Trichomonas. 



These he considers to be female forms, and says that he has seen conjugation 

 with male forms. 



Trypanoplasma ventriculi KeysseHtz, 1906. 

 Synonyms. — Heteromita dahlii apstena = Diplomastix dahlii. 

 This is found in the intestine of Cyclopterus lumpus, and is apparently a 

 typical tr3rpanoplasma. Discovered by Dahl in 1887. 



Trypanoplasma varium Leger, 1904. 

 In Cobitis barbatula (loach), and in Hemiclepsis marginata. 



Trypanoplasma guernei Brumpt, 1905. 

 In Coitus globio, and develops in Pisciola. 



Trypanoplasma barbi Brumpt, 1905. 

 In Barbus fluviatilis, and in the leech (Pisciola). 



Trypanoplasma abramldis Brumpt, 1905. 

 In the bream (A bramis brama) and the leech (Hemiclepsis) . 



Trypanoplasma truttse Brumpt, 1905. 

 In Salmo fario, and perhaps in Pisciola. 



Other Species. 



T. keysselitzi Minchin, 1909, in the tench; T. gurneyorum Minchin, 1909, in 

 the pike; T. claries Mathis and Leger, 191 1, in Clarias macrocephalus , T. congri. 



Trypanophis Keysselitz, 1904. 



Bodonidae in Ccelentcvata, with two flagella, an anterior and a posterior. 



The kinetonucleus is situated anteriorly, and is much smaller than the 

 tropho nucleus. According to Floyd, a blepharoplastic granule gives rise 

 to the free flagellum. The attached fiagellum arises near the basal granule 

 of the free flagellum, and gives rise to a narrow undulating membrane, 



Trypanophis grobbeni Poche, 1903. 

 In the gastro- vascular system of different Siphonophora — e.g., Halistemma 

 ergestinum. The parasite is curved somewhat, like a trypanosome.
