now further peculiarities presented themselves. The girdle was 

 advanced two or three segments, though the spermathecae remained 

 in the normal position. No salivary glands could be discovered 

 either in adult or immature s]3ecimens, but a pair of glands of a 

 peculiar type could be traced in young specimens in the segment 

 which the sali varies usually occupy. Further, between the third 

 and fourth pair of septals a new pair of glands, or, in one case at 

 least, an unpaired gland, looking like the diverticulum found in 

 the genus BuchJiohia, or the oesophageal glands of the Henleas, 

 had come into existence. The spermathecse were fully developed, 

 and were of very characteristic form (fig. 22), as were also the

funnels of the sperm-ducts. The setse were /-shaped or sigmoid, 

 and almost invariably three per set. The nephridia (fig. 23) were 

 striking alike in size, shape, and position ; but one of the most 

 remarkable features was the apparently entire absence of a vascular 

 system. In one instance it seemed just possible to detect the 

 presence of some kind of dorsal vessel near the girdle, but the 

 characteristic Enchytraeid system was in these specimens, to all 

 appearance, absolutely wanting. This is due to the delicate 

 character of the walls of the blood-vessels.
