The nepliridiopores are obvious and lie in front of seta 3. 



The spennathecal pores are between segments vii./viii., viiL/ix. 

 They are in front of and a little to the outside of seta 2. 



The oviducal 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 setae, 

 both of which are present upon segment xviii. 



The worm has an unusual number of genikd 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 setse ; 

 they are flattish circular in outline, and appear as if perforated by 

 a pore in the tuiddle. In a smallish specimen without the clitellum 

 all the papillae enumei'ated 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 present with the exception of that 

 upon segment xxiv. It is not usual for the papillae to be so plaia 

 in immature examples of earthworms. 



There is a large gizzard which I ascertained, by making a longi- 

 tudinal 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- d^Mt 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.

Penial setae oi 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 accom- 

 panying drawing (fig. 1). When examined under a low power 

 the end of the seta has the appearance of the " saw " of a Sawfish,
