xxth, which marks the limit of divergence, have got to he wider 

 apart than they are on the anterior segments of the body. They 

 continue to the end of the body without any further change. 



I could see no dorsal pores. 



The clitellum, as has been already mentioned, was not developed 

 in the type. In an example from Putabla it occupies segments 

 xiv.-xvii. 



The gizzard lies in segment vii. 



The specially thickened septa are few in number. As a general 

 rule in this and, indeed, in other genera, the thick septa begin with 

 the second septum ; in the present species this is not the case ; 

 the thickened septa are only two, those separating segments x./xii. 

 The capacity of the xth segment is very limited. The septum 

 which divides it from the segment lying in front is closely applied 

 to septa x./xi. In the narrow room thus formed lie the testes 

 and the funnels of the sperm-ducts. 



The I'acemose sperm-sacs lie in segment xi. 



The single pair of spermathecse are small, perhaps on account of 

 the immaturity of the worm. The form is not particularly 

 remarkable ; the sac has a diverticulum not quite so long as itself 

 but narrower. 



The spermiducal glands are not particularly large. They are 

 confined to their segment. In the single bundle of penial setae 

 which I examined, I found three penial setae of about the same 

 length and general appearance except as regards colour ; one of 

 the three setae was a very pale colour, while the other two were 

 bright yellow. I presume that the first-mentioned seta was 

 immature. All of them end in a bluntiah point and are quite 

 unornamented.

From EstanciUa (St. 41) was collected a larger individual, which 

 seems to be, though it is difficult to be quite certain, a sexually 

 mature specimen of the same species. This worm is 72 mm. 

 long by 7 mm. in diameter, and consists of 82 segments. The 

 clitellum occupies segments xiv.-xvii. There are a number of 

 genital papillae ; a pair on each of segments ix., xv., xvi., and an 

 asymmetrical one on xiv. ; on each of segments xvii. and xviii. 

 there are three papillas. The spermiducal glands of the mature 

 worm have a warty appearance ; the penial setae are very faintly 

 ornamented with transverse ridges. 



(8) Microscolex diversicolor, n. sp. 



A good many examples of this species were collected in Valdivia, 

 in Chile. It is a worm which has an exceedingly marked colora- 

 tion, and is therefore always conspicuous in any collection. The 

 colour of the dorsal surface is a bright purplish red, extending on 

 to the sides of the body beyond setae. The dorsal setae are im- 

 planted in areas which are equally conspicuous on account 

 of the fact that they have no pigment and appear white. In some
