begin in segment ii. Their average length is about ‘087 mm. ; the 
longest measured was ‘094 mm. The prongs of the fork are at a 
wide angle to each other, the distal being usually, not always, the 
longer, about 14 times as long as the proximal; the proximal 
however is the thicker, 14 times as thick as the distal prong at its 
base. There is a nodulus, which is situated distal to the middle 
of the shaft ; its exact position varies only slightly, the proportions 
between the length of the shaft proximal and distal to the nodulus 
being about as 5:3. The number of sete per bundle varies 
from three to six in the anterior part of the body, and in the 
posterior is regularly two per bundle. There are no ventral sete 
on the segment which bears the male aperture (xi or xii), An 
examination in balsam of the specimen with five spermatophores, 
referred to below, seems to show that the dorsal sete of segment 
xi (that of the maleaperture) are small and singly pointed. 
Fic. 1—Two spermatophores from the same individual, showing their 
deformations when empty. 
The sensory depression on the prostomium has the characters 
described by Beddard; it is variable in position, and may be 
nearly terminal. 
The cltellum varies in position. It may be on segments xi 
and xii, or on xii and xiii. 
The male aperture, single, median and ventral, varies in posi- 
tion with the clitellum ; it is on xi or xii, accordingly as one or 
other of these is the first segment of the clitellum. In one case the 
clitellum extended over 4 xi, xii, and xiii; ventral sete were 
present on xi, and therefore the male pore was probably on xii, 
though owing to distortion at this place it could not be actually 
seen. 
The setal distribution on these segments varies, as already 
said, according to the position of the male aperture, ventral sete 
being always absent from the segment in which this occurs. They
