host, Bo thus rhombus (Rhombus Isevis), brill. Associated with a 

 new Hsemogregarina, H. bothi. 



Brumpt and Lebailly (11) have briefly described a number of new Piscine 

 Trypanosomes, and also, at the same time, several new Hajmogregarines, 

 many from the same hosts as the Trypanosomes. 



T. limandte, Brumpt and Lebailly, 1904. — An extremely thin, mam- 

 malian like form, differing from T. platessse in having a much longer 

 flagellum. Length 45 /t, of flagellum alone 20^. Breadth only 2 — 2h n. 

 Anterior extreuiity very pointed. (V.) host, Limanda platessoides. 



T. delagei, Brumpt and Lebailly, 1904. — A shorter form than the fore- 

 going, but also thin and fusiform. Length 33;it, flagellum alone 12^. 

 Breadth 2|jit. Anterior part pointed and rectilinear (?). Host, Blennius 

 pholis.

The remaining forms are larger, and relatively much broader, and agree 

 with the majority of parasites from flat-fish above described in possessing a 

 very short flagellum. 



T. gobii, Brumpt and Lebailly, 1904. — Length 66/1, of flagellum alone 

 10/i. Width 5 — 5^11. Anterior extremity generally somewhat blunt or 

 rounded. (V. ) host, G o b i u s n i g e r. 



T. cotti, Brumpt and Lebailly, 1904. — Length 53 /i, of flagellum 8/x. 

 Width about 5/^. Anterior end fairly short and rounded. This parasite, 

 especially in the case of the largest individuals, resembles T. gobii. 

 ("V.) host, Cottus bubalis. 



T. callionymi, Brumpt and Lebailly, 1904. Length 70 /x, of flagellum 

 alone about 5 /x (in some cases up to 8 fi). Breadth 5/x. Anterior extremity 

 Ion" and tapering. Correspondingly, the Icinetonucleus is situated some 

 distance from the end. (V.) host, Callionymus dracunculus. 



Lastly, both divisions of the Elasmobranchs furnish hosts for these 

 ubiquitous parasites. 



T. scyllii, Laveran and Mesnil, 1902. This is a very large parasite, 

 bein"- from 70 — 75 n long, by 5 — (5 A* broad ; free flagellum about 14^ long. 

 The body is generally rolled up on itself (fig, 62 a), often forming a com-
