A considerable number of specimens were collected in a garden 

 in Valparaiso. They vary greatly in size, some being mature and 

 others not so. 



The biggest specimen is 84 mm. in length by 5 mm. in diameter. 

 The number of segments of this individual was 117. 



The colour of the Uving worm is described by Michaelsen in the 

 following terms : " schmutzig grau ; vorne schmutzig fleischfarbe ; 

 Giirtel weiss bis braunlich." The preserved worms are of much 

 the same colour. 



During life the worm was remarkable as " lebhaft schlangelnd 

 bei Beriihrung." 



The setae are strictly paired. Dorsal pores are present. 



The clitellum occupies segments xiii.-xvii. There is a median 

 genital papilla upon segment xvi. ; the male pores are on xvii. 



The prostomium, as in so many species of the genus, is completely 

 carried over the buccal segment by grooves. The first setigerous 

 segment has in most specimens a furrow on the dorsal surface 

 which extends right across that surface, but is not visible ventrally. 

 This gives a little the impression that the prostomium is an 

 incomplete one. 



The gizzard is large ; it lies in segment vi. It is immediately 

 followed by a thin and delicate septum, behind which are five septa, 

 moderately thick. The last heart is in the twelfth segment. 



The sperm-sacs are in the ixth and xith segments ; those of 

 the latter segment are so coarsely racemose that they appear to be 

 formed of a number of small separate sperm-sacs ; this does not 

 apply to the anterior pair. 



The spermiducal glands are different from those of any other 

 Microscolex which I examined in their regular tubular form and in 

 the complex coiling ; they look much more like the corresponding 

 glands of certain Acanthodrilidse. Moreover, the duct of the gland 

 is unusually conspicuous ; it is also long and is not more than one- 

 third of the diameter of the gland. It has a distinctly nacreous 

 glitter. In common with the spermiducal glands opens on each 

 side of the body a sac of penial setse ; there are two of these on 

 each side. They are very yellow in colour and have a bent bow- 

 like form. The extrea)ity is only moderately pointed and a little 

 flattened and expanded. Fine spinelets ornament the extremity. 



The spermathecse in segment ix. are particularly large. The 

 racemose diverticulum is borne at the end of a long muscular 

 stalk.

(2) Microscolex longiseta, n. sp. 



This is a small, rather transparent species, with little or no trace 

 of integumental pigment. 



* From each of the last two stations a single indiyidual frohably of this 

 species.
