glands occupy segments xv and xvi, but in two specimens dis- 

 sected the arrangement was as3'mmetrical, as follows : — The greater 

 part of the gland of the right side was contained in xv, a small 

 part only being in xvi ; while the reverse was the case on the left 

 side. The glands are white in colour, antero-posteriorly com 

 pressed, attached round the side of the oesophagus, and meeting 

 each other in the mid-dorsal line above the oesophagus ; they are 

 lobed, the lobes being arranged as a single row around the 

 oesophagus ; the lamellae in the interior have an antero-posterior 

 direction. The intestine begins in xvii. 



The last heart is in xiii. 



The excretor\' system is micronephric, the nephridia being 

 numerous and small ; they are especially abundant on the inner 

 surface of the body-wall in the clitellar segments, on the posterior 

 part of the pharynx and on the first part of the oesophagus. 



The male organs show the peculiarity described by Michaelsen. 

 In segment x were found a pair of funnels, comparatively small, 

 and not iridescent, but not testes ; in segment xi testes were 

 present, of moderate size, and also relatively large iridescent 

 funnels ; these organs in segment xi were enclosed with the testes 

 in testicular sacs, in segment x they were free. 



The seminal vesicles and prostates agree with Michaelsen 's 

 description. 



A pair of ovaries, branched, with a number of finger-like 

 processes, occur in segment xiii, with a pair of funnels. A second 

 pair of ovaries occurs in segment xiv ; they are of at least equal 

 size with those in xiii, but are more compact, resembling a bunch 

 of grapes ; and (at least in one of the two specimens dissected) are 

 more doisally situated in the segment, being attached to the septum 

 at its junction with the alimentary canal so that they lie dorso- 

 laterally to the latter. In both specimens microscopic examination 

 confirmed the ovarian nature of the structures. Funnels were 

 absent in segment xiv. 



The spermathecae are two pairs, remarkable for their small 

 size ; they are situated by the side of the ventral nerve cord. The 

 ampulla is ovoid, and is continued by the duct, which is short and 

 relatively broad. The diverticulum is small, half the length of 

 the ampulla, and dilated at its end ; it was overlooked at first, 

 since it arises from the very base of the duct where it pierces the 

 body-wall, and itself lies close on the body-wall. 



The penial setae difier in some degree from the previous 

 description of this species (Michaelsen, 4), and are therefore 

 illustrated in fig 6. In length they are 550M, in breadth 15/u ; 

 the shaft is almost straight, except for a simple curve at the 

 distal and a slight bending at the proximal end. The tip is 

 simple, tapering, and pointed. A few teeth lie flat against the 

 shaft in the region of the distal curvature. 



There can hardly be any doubt as to the specific identifica- 

 tion of these specimens. I have, however, given a prett}' full 

 description, because, as Michaelsen says, the species is an interest-
