boundary segments x./xi., is a siugle median papilla, upon the 

 middle of each of which is a row, concave forwards, of large pores, 

 which appear to correspond to glands like the capsulogenoag glands 

 of Perwhcetm. Such glands have , already been met with in 

 Acauthodrilids (in Acanthodrilus rosm), another fact among many 

 which show the intimate relationship between the two families. 



The ditellum occupies segments xiii.-xvi. 



The nephridia are of the diffuse type. 



The first septum separates segments iv./v. The next three are 

 moderatly thickened, and after the last of these come four, which, 

 though not quite so thick, are to some extent strengthened. All 

 these septa, beginning with the first mentioned, are attached to 

 each other and to the parietes by numerous tendon-like muscular 

 fasciculi. These latter extend for a segment or two farther back 

 than that which is bounded by the last thickened septum. The 

 last heart lies in the xiith segment. The dorsal blood-vessel is 

 single. Two stout gizzards immediately following each other lie 

 in segments v. and vi. In segments xi. and xii. are a pair of 

 calciferous glands. The intestine seems to begin in segment xvi. 

 and has a well-developed iyphlosole, which, however, is not 

 apparent for the fiist ten segments or so, though it may be possibly 

 present earlier as a rudiment. 



The sperm-sacs are a single pair in xii. This, however, may be 

 a question of immaturity. On the other hand, although I detected 

 two pairs of funnels belonging to the sperm-ducts, I could only see 

 the testes of segment xi., and the funnels of segment x. were 

 distinctly smaller than the posterior pair. 



The spermiducal glands are very long and coiled. There appear 

 to be no penial setae associated with them. 



The spermathecce are as usual in viii. and ix. The diverticula 

 near to the external aperture are inconspicuous, but apparently 

 tri- or quadrifid.

" Bemarks. — Though I do not propose, for the present at least, to 

 create a new genus for this species, it differs in several points 

 from any known member of the genus Benhamia. It comes nearest 

 perhaps to Benhamia inermis, with which it agrees in absence of 

 penial setse and in the position of calciferous glands
