A row of small darkish spots may be present, in a transverse 

 line, over the middle part of the pad in 1; similar minute spots 

 were seen, also in a transverse line, on the anterior of the four 

 pads in the male genital field. 



Septum i; is the first; this, and all the following septa as far 

 as H are moderately to considerably thickened. 



The first gizzard is in front of the first septum, i.e. in 

 segment v, of considerable size, subglobular and not very hard ; 

 a second gizzard resembling the first occupies segment vi. Cal- 

 careous glands are two pairs, in segments xi and xii ; they are 

 more or less globular, yellowish in colour, and set off from the 

 oesophagus. The intestine begins in xv. 



The dorsal vessel gives off a regular series of commissural 

 vessels (' hearts') from xiii to v and can be traced forwards on to 

 the pharynx. 



Regular lines of micronephridia are found in all the post- 

 clitellar segments. In front of the clitellum they are less regular 

 in disposition ; in segments ii and iii they are numerous and 

 close-set on each side of the pharynx. 



Considering in more detail the post-clitellar nephridia: — 

 in the anterior portion of this region, which is exposed during 

 the ordinary dissection, there are eight, or about eight, microne- 

 phridia on each side, arranged in a row of which the ventral- 

 most member lies by the side of the ventral nerve cord ; the 

 most dorsally situated nephridium in each segment is at some 

 distance from the mid-dorsal line, so that there is a dorsal tract of 

 the body- wall which is free from nephridia. Of the eight (or so) 

 nephridia on each side, the three most dorsally situated are larger 

 than the rest, and consist each of a transversely directetl loop, 

 lying in the middle ©f the length of the segment and without 

 connection with the septa. The inner five or thereabouts of the 

 row of nephridia are considerablj^ smaller; there is no very con- 

 stant diminution in size on passing ventralwards along the row ; 

 still it may perhaps be said that the nephridium which is placed 

 most ventrally, b}- the side of the nerve cord, is on the whole the 

 smallest of the serits. 



If now the posterior end of the animal be opened, a difference 

 is found. For the most part the nephridia have the same relations 

 and sizes ; but the most ventral nephridium on each side is here 

 much larger than further forward. While anteriorly the ventral- 

 most nephridium was the smallest, here it is, I will not say the 

 largest, but as large as any of the series. It is not, in fact, larger 

 than the dorsalmost of the series ; though its tube is thicker and 

 more opaque, and it is coiled more compactly than the trans- 

 versely elongated loop of the dorsally situated organs. J could 

 not make out that these ventral nephridia are attached to the 

 septa, or pass through to end in a funnel on the other side. 



Testes and seminal funnels are present, free, in segments x 

 and xi. Large lobed seminal vesicles are situated in ix and xii, 

 with the usual relations to the septa In one of the three speci-
