ON NEAV WORMS OF THE FAMILY EUDRILID.E. [Apr. 23, 



of Eminoscolex, the region of the sperm-ducts in question is not 

 only widened but is of some length and coiled, forming a body of 

 oval contour constituted by the closely approximated Avindings of 

 the tube. It is conspicuous through its white colour as in other 

 Eudrilidfe. The sperm-duct opens into the tip of the spermiducal 

 gland (text-fig. 127), which is in this species directed forwards ; the 

 entire gland is sausage-shaped and bent once upon itself. It ends 

 in a nari-ow muscular duct which opens into the rather large 

 Bursa propulsoria ; the latter is of circular contour. There are 

 no penial setfe.

The femcde organs of generation were so much softeiied that 

 some details have probably escaped me. It is, however, plain 

 that there are a pair of nearly spherical spermathecal sacs which 

 are perfectly free from each other and do not communicate, as in 

 some species of the genus, at the distal extremity with each other. 

 The oviduct is very long and straight in its course ; anterioi-ly it 

 is seen to communicate with a rather small receptaculum ovorum, 

 which lies close to the septum dividing the xiiith from the xivth 

 segment to the outside of the oviduct. In the other side is a slight 

 swelling Avhich appears to be fixed against the septum dividing 

 the same segments, which doubtless represents the " Eitrichter- 

 blase " and the " Ovarialblase." I am doubtful whether this 

 chamber is also in communication with the spermathecal sac 

 or surrounds it. It is not, however, necessary to settle this 

 point for purposes of the identification of the species, which I 

 believe is sufliciently distinguished from other species of the genus 

 hithei"to described. Of these there are ten species known. 



A peculiarity of Eminoscolex ruweiizorii is the thickened fold
