They are in front of and a little to the outside of seta 2. The ovlducal pores are exactly in front of seta 1. The orifices of the spermiducal glands correspond to the ventral couples of setae ; the two of each side are connected by a straightish groove which passes to the outside of the ventral couples of seta?, both of wdiich are present upon segment xviii. The worm has an unusual number of genital papillce. In the sexually mature individual which I make the type, and from which the present description is taken, there are a pair of papillae on each of segments x., xi., xii., xvi., xxi., xxii., xxiii., xxiv. These papillae lie between and in front of the ventral couples of setae; they are flattish circular in outline, and appear as if perforated by a pore in the middle. In a smallish specimen without the clitellum all the papillae enumerated above were present with the addition of a pair upon the xiiith segment. In a larger worm, also without a clitellum, the same number were p*resent with the exception of that upon segment xxiv. It is not usual for the papillae to be so plain in immature examples of earthworms. There is a large gizzard which I ascertained, by making a longitudinal section of the anterior end of another specimen of the species, to lie in segment vi. On dissection it appears to lie much further back owing to the backward slope of the intersegmental septa in this region of the body. The large intestine begins in segment xvi. The sperm-sacs are racemose and lie in segments ix.-xi. The sperm-duct funnels are in segment x. The two pairs of spermathecce are not large, and lie as usual in viii. and ix.; the single diverticulum of each is in the segment in front of that which contains the pouch. The spermiducal glands are short and stout. Fig. 1. Penial seta? of Acanthodrilus purcelli. Penial setce are present. I found in the individual selected for examination five of these setae in a bundle. They are short and excessively spiny at the free extremity, as is shown in the accompanying drawing (fig. 1). W h e n examined under a low power the end of the seta has the appearance of the " saw " of a Sawfish, |
