Male pore, oviduct pores (in front and just ventrad of the inner- 

 most setaB), spermathecal pores, dorsal pores, and nephridiopores as 

 in C. unicus. 



Alimentary canal : the cesophagus longer, and the gizzard farther 

 back, than usual, the former extending through v, vi and into vii, 

 the latter at first sight appearing to be contained in segments vii 

 and VIII, the mesentery between these two surrounding it at about 

 its middle, but investing it posteriorly ; from x or xi to at least 

 XIV (behind which in the specimen dissected the canal was 

 damaged) the interseptal portions are dilated possibly functioning 

 as calciferous glands, and in xiii and xiv there are incompletely 

 pinched-off pouches. 



Genitalia : two pairs of testes and ciliated rosettes in x and xi ; 

 vesiculse seminales five pairs in ix-xiii, the first two pairs small, 

 the last pair still smaller and rudimentary, the third and fourth 

 pairs very large ; a single vas deferens on each side joining the 

 pi'ostatic ducts a little way from the prostates. Spermathecee a 

 median series of five single stalked, rather long pouches, sacculated 

 in appearance, in segments v-ix, each of them with two linear, 

 long (but shorter than the pouches) almost cylindrical caeca, one 

 on each side. 



Last pair of hearts in xii. 



Nephridia : a pair of tubules to a segment after the first, con- 

 sisting as well as I can make out of at least three portions, viz., a 

 distal convoluted portion whose free extremity lies in the segment 

 in front of that to which the nephridium belongs, a shorter 

 narrower middle portion, and a proximal still shorter vesicular or 

 dilated portion with a lateral diverticulum.

This distinct species difi*ers from both C. unicuSyS^ndi C. fur^ureus 

 in having the body more robust and transversely striped, and from 

 the latter in addition in the rows of setae being straight. These 

 three species form a group of closely allied forms whose claims to
