only moderately long, not so long as in the examples of P. 

 henguetensis. The spermathecje differ from those of the large 

 worms with which the present worm is compared mainly by 

 the fact that the diverticulum is not so long as is the sper- 

 matheca itself. There are, also, some differences among in- 

 dividuals. In 1 specimen there was, as already mentioned, a 

 small accessory diverticulum; in 2 other individuals the Vllth 

 segment contained 2 spermathecse at any rate on one side of 

 the body; of these, one opened on the intersegmental furrow 

 VI/VII, the other on VII/VIII, so that externally there was no 

 variation from the normal. In one there were only 3 pairs. 

 The ovaries lie in segment XIII and are particularly large and 

 of a bushy appearance. The same segment, also, contains a 

 considerable number of large monocysts. Both ovaries were 

 removed and placed upon a slide and away with them came 

 a number of these monocysts which were clearly attached to 

 the ovaries. This is a very remarkable point of likeness between 

 this species and the next that the Xlllth segment of Pheretima 

 henguetensis also contains a group of large gregarines appar- 

 ently quite similar to those of P. decipiens. But in P. hen- 

 guetensis the ovaries were small, although easily recognizable, 

 and a pair of sacs was found close to them which may be 

 sperm sacs or ovisacs, whereas in P. decipiens those sacs if 

 present must have been very small. The sperm sacs lie in 

 segments XI and XII and are about equisized. Each has a free 

 projecting lobe as in P. henguetensis and various other species. 

 In the present species these free projecting lobes are asym- 

 metrical. Of the posterior pair of sperm sacs, that on the 

 right is the longer; the converse is the case with the anterior 

 pair. These appendices do not cap the sperm sacs as in the 

 species with which I am particularly comparing Pheretima deci- 

 piens, for the sperm sacs grow up on either side beyond the 

 origin of the appendices. It is probable, however, that mor- 

 phologically their position is the same. The sperm reservoirs 

 appear to be much the same as in P. henguetensis. There is, 

 however, a difference as regards the sperm-duct funnels. These 

 latter are obviously dependent into the sacs from the septa, a 

 difference which may be due to smallness of size of the present 

 species. 



The spermiducal glands and the terminal bursa copulatrix 

 are very like those of P. henguetensis. They vary somewhat 

 in different individuals of the present species. The gland has 

 the same compact form and semicircular, or horeshoe-like, out-
