In 1908 1 the description by Dr. Marianne Plehn of Sanguini- 

 cola as the only known example of a Cestode (Cestodarian) 

 mfestmg the blood aroused considerable interest, and though 

 the subsequent conclusion by Odhner in 1911 ^ that Sanguinicola 

 was rather to be regarded as an extreme form of suckerless 

 haematobic Trematode somewhat detracted from the signifi-" 

 cance of the discovery, yet on account of its plesio-Turbellarian 

 structure and possible Turbellarian affinities, Sanguinicola still 

 remams a zoological type of importance. 



So far as I am aware, Sanguinicola has, up to the present 

 solely been found in Germany in the blood of Cyprinidae ^ 

 and it was therefore a source of gratification to me to discover 

 m the large collection of slides of Helminth material made by 

 the late Dr. A. J. Chalmers when Director of the Wellcome 

 Tropical Eesearch Laboratories at Khartum and kindly 

 presented to the Wellcome Bureau by his successor. Major 

 R. G. Archibald, some thirty specimens of Sanguinicola 

 obtamed from the blood in the heart of the Nile Siluroids,
