typicall}' a pair of circular or roundly oval papillae, meeting or 

 almost meeting in the middle line and extending outwards to be- 

 yond the line of seta &, — that is, to the outer border of the ventral 

 surface ; they are quite flat, and take up the whole length of the 

 segment, encroaching also on to segment xv ; they may be scarcely 

 raised above the general surface ; and, in one instance at least, 

 could be distinguished into a central whitish portion surrounded by 

 a darker groove, with a whitish lip outside all. On segment xviii 

 there may be a pair of similar, even larger papillae extending for- 

 wards onto xvii, and meeting in the middle line with only a narrow 

 groove between them ; these obvioufely correspond to the approxi- 

 mately rectangular cushions on this segment, which also are sepa- 

 rated from each other in the middle line by a narrow groove, des- 

 cribed in the original account. In one specimen there was present 

 on segment xxii midventrally a large transversely oval papilla, 

 taking up the whole length of the segment and extending to 

 between setae a and h on each side 



The female apertures are small, and placed near each other in 

 a darker patch rather in front of the middle of the length of segment 

 xiv. The spermathecal apertures seem not to be visible externally. 



Internal anatomy. — The first septum may be 4/5, as stated in 

 the previous account; but here its attachment seemed, in two 

 specimens dissected, to be either at 5/6 or between 4/5 and 5/6. 



The calcareous glands are large, but asymmetrical ; on the 

 left side the gland is mostly in segment xv, on the right in xvi, — 

 the disposition being such that the anterior part of the left gland 

 gets in front of the posterior part of the right, the dorsal vessel 

 passing obliquely between them ; the opening of the glands seems 

 to be in xv on both sides ; the glands are lobed, and septum 14/15 

 is markedly bulged forwards on the left side. 



In the former account I stated that the testes and funnels 

 were free ; the statement has now to be modified, at any rate for 

 the present specimens. Testis-sacs are present ; that in segment 

 xi is large, single, and extending dorsally covers over the hearts 

 and alimentary tube ; in one of the dissected specimens it was 

 constituted by a fine membrane stretching between septa lo/ii 

 and I1/12, while in the other it was free from both septa, with a 

 slightly lobed border. The anterior sac in one case resembled the 

 posterior in being constituted by a membrane stretching between 

 the septa ; in the other it was, like the posterior in that specimen, 

 free from the septa, and indeed narrow from front to back. 



The prostates are of moderate size, and are composed of a 

 number of closely apposed coils ; the duct is thin and twisted, of 

 considerable length when extended, and without any thickening in 

 its course. 



The shape of the spermathecal ampulla varies very consider- 

 ably. The diverticula may be absent, or there may be one, or 

 two ; again they may be sessile, or narrowed at the base, or even 

 definitely stalked ; three or four chambers may be indicated in the 

 diverticulum, or the surface may be smooth without any lobula-
