lias the same bowed sliape as in other OdochHi. I think 

 that all the setje arc present at least on segments xvii and 

 xix. In any case, I distinctly identified the ventralinost 

 seta of segment xix, and detached also a pair of setiu u-jtli the 

 spenniducal gland of the same seL;:nient. I do nut tliink that 

 there are anv penial s< tfe. Indeed, the existence of such 

 would be hardly expected from the j)Osition of the various 

 pores of the male system. 



(Jf the internal anatomy I am not able to give a comj)lcte 

 account; but I can call attention to a few facts which aj)pear 

 to aid in establishing the speciHc distinctness of this form. 

 The gizzard is single and large and lies in the segment near 

 to the spermatheca?, but lam unable to fix the exact segment 

 which it occupies. 1 consider this segment to be vii or viii. 

 There is a single pair of unusually large calciferous glands in, 

 1 think, segment xv — the same segment in which tlu^y occur 

 in (Kiocliatus Aitkeai. They arc, however, rather different 

 in sh;ij)e in tlie two species. In the ])resent species they arc 

 long and curved round the intestine, embracing it closely ; 

 they suggest a ram's horn in shape, and are divided by 

 constrictions into a series of lobes, which heightens the 

 resemblance. 



The intestine is provided with a strong typhlosolc, which 

 ceases some little way before the end of the body. The 

 tvphlosole consists of a double fold projecting into the inferior 

 of the intestine. The dorsal blood-vessLd is single and the 

 last pair of hearts are in segment xiii. 



'Jdie nephridia are, as 1 have already mentioned, diffuse. 

 The most striking feature about the organs of reproduction 

 is the small size of the various parts of this system. The 

 conditions which characterize the present species are also 

 found, though not to so marked a degree, in the closely allied 

 Benhamia Aitkeni, 1 do not think that this is due to imma- 

 turity, since the clitellum is so fully developed. I should 

 rather compare Ocioch(vtus Beatrix in this particular with the 

 two species of Pheretima, P. tapruhinue and P. virgo. Of the 

 former of these two species a very large number of examples 

 have been examined both b}- myself* and by Dr. Michael- 

 sen f, and the reproductive organs seem to be always small. 

 In P. virgoX the same condition is met with, though the 

 number of specimens dissected was much less, and tiiere is 

 therefore room for doubt as to the mature or immature con- 

 dition of the few specimens examined.
