of 19 specimens sent to Beddard. None of these 12 intact speci- 

 mens can be regarded as the type of A. sclateri (spermathecae with 

 two long tubular diverticula). These 12 specimens mostly belong to 

 the species Chilota excavatus (Bedd.), whilst one proved to repre- 

 sent the new species Chilota knysnanus (see above) ; another 

 specimen belongs to Chilota lucifnya (Bedd.), and the last one 

 either to the same species, or to Ch. photodilus (Bedd.). The 3 

 fragments probably are Ch. excavatus. The real type of Acantho- 

 drilus sclateri, if there existed a single type, perhaps has been 

 totally dissected by Beddard, unless it forms a part of those 

 specimens retained by him. I cannot help suspecting that A. 

 sclateri is no real species at all, but that the diagnosis of it is 

 composed out of the characters of different species, probably among 

 them a Microscolex or an Eodrilus species ; for in these genera 

 the occurrence of "two long tubular diverticula" at the sperma- 

 thecae is less rare than in the genus Chilota. Acanthodrilus 

 sclateri, therefore, must be regarded as a " species inquirenda," if 

 not as a " species spuria." 



FAMILY GLOSSOSCOLECIDAE. 



MlCROCHAETUS PERINGUEYI, n. Sp. 



Loc. Nieuwoudtville in the Bokkeveld Mountains, Calvinia 

 Division. 



External Characters. Length 330 mm., thickness 6-10 mm., 

 number of segments ca. 445. 



Head prolobous. 4-9 segments divided each into two segment- 

 like ringlets. 



Setae very tender, laterally beginning behind the clitellum, ven- 

 trally beginning apparently at the 9 segment. Setae very strictly 

 paired. Behind the clitellum aa : be : dd -- -- 4 : 6 : 8 ; at the hinder 

 end of the body aa : be : del - - 4 : 5 : 6. Ventral setae of the clifcellar 

 region transformed to sexual setae, about O'9-l'O mm. long, and in 

 the width 50-55 yu thick, bent like an " S," without nodule, roundly 

 tri-carinated and simply pointed at the distal end, without orna- 

 mentation. 



Nephridial pores considerably beneath the lines of the setae c, but 

 much nearer to these than to the lines of the setae b. 



Clitellum at the (12) 13-25 segments ( = 13, if not = 14), apparently 

 saddle-shaped. At each side a broad copulatory cushion extending
