This species has been investigated by a number of naturalists, whose names are 

 given in the above synonymy. I include in one species not only the three species 

 described by PERRIER, but also the two species described by myself and the supposed 

 new forms described by HORST and MICHAELSEN. The accounts given by these various 

 writers do not appear to me to give any characters which serve to distinguish species. 

 PERRIER'S account was defective owing to the poor condition of the material which 

 he had to work with. The characteristic feature of this species as compared with 

 the other is the presence of peculiar appendices to the bursa copulatrix which are 

 shown in the woodcut on page 112 ; the two appendices are sometimes independent 

 and sometimes fused together at the end to form a single horseshoe-shaped appendix. 

 The glandular appendix of the spermathecal sac in this species is subdivided by 

 trabeculae into a number of compartments ; it opens into the duct of the sac at 

 a point exactly opposite to the entrance of the oviduct. The spermiducal gland is 

 divided by a median septum into two chambers, into one of which only open the 

 sperm-ducts. I found in one specimen (examined for this purpose) that the last 

 heart was in xii and the first pair of nephridia in iv. 



Through the kindness of Prof. LOVEN I have been able to examine for myself 

 KINBERG'S 'Lumbricus eugeniae,' which I cannot distinguish from the other 'species' 

 enumerated in the above list of synonyms. The name Eugeniae must therefore, 

 I think, stand for the species. The only discoverable ground for regarding my 

 E. sylvicola as distinct, is its smaller size.

 sac has two diverticiila at base as well as the appendix found in E. decipiens. Hah. 

 Accra, W. Africa.
