How far this character is constant remains yet to be demon- 
strated, though Ude has made elaborate investigations which seem 
to indicate that its value is not to be despised in diagnosis. It will 
be seen, if the foregoing chart is reliable, that there is at present no 
_ apparent relationship between the position of the first dorsal pore 
and the first clitellar papilla. 
The sete are in four couples on each segment, and are slightly 
wider apart than in the other species. On account of the presence 
clitellar papilla in this species and no other, I have named it 
L. papillosus, a designation which I think well calculated to express 
the principal feature. Rosa has recently pointed out the fact that 
_ Miller has already adopted the term fafil/osus for another species 
_ Of annelid. 
Following the diagnosis of the Ruddy Worm (Z. rudescens Fr.), 
and that of the other species found in Eisen’s memoir, I now give 
__ a brief description of the new species.
