b. The portion in front of the former supports a num- 

 ber of female bundles with large brick-coloured eggs. 



c. The anterior portion carries a number of somewhat 

 smaller male bundles. 



d. Foremost we find the common dusters and club- 

 shaped bodies. 



Specimen 7. Caught July 13, 1900. Length about 175 mm. 



a. The posterior portion of the genital basis is of the 

 ordinary shape, and is provided with macultE and pro- 

 cesses, one of which bears four, 4 mm. long branches, 

 filled with eggs. 



b. In front of the former there are to be seen 12 large 

 female bundles, containing large, nearly ripe, brick- 

 coloured ova. 



c. In front of these are situated 15 immature male bun- 

 dles, the posterior ones being, as a rule, the largest, 

 and having a length of 16 mm. 



d. Anteriorly to these we have 8 — 10 small bundles of 

 female tubes, about 7 mm. long, with unripe ova. 



e. Foremost may be observed the common minute buds 

 or dusters.^ 



Specimen 8. Caught November 1900. Length about 250 mm. 



a. The total length of the whole genital basis from the 

 minute, anterior bud-like follicles to the poste- 

 rior curved end, measures about 6 mm. Its naked 

 portion possesses three sets of marks: posteriorly about 

 18 rounded, light brown maculse; an intermediate set 

 of 12 to 14 small knobs of a brownish colour, separa- 

 ted from the former by a narrow naked band, and in- 

 creasing in size forwards; finally an anterior set of 

 small, 4 to 5 mm. long, bundles of processes. 



b. In front of the former are situated about 18 bundles 

 af male tubes, the largest measuring only 14 mm. in 

 length. 



c. Anteriorly to these, 15 to 20 small bundles of female 

 tubes have their place, the largest being only 5 mm. 



^ Aniong eight more specimens oLtained by dredgings on the same day 

 and from the same locality three had the posterior genital bundles filled with 

 nearly ripe ova, while the remaining five had them filled with ripe sperma- 

 tozoa. In one instanee I counted more than 100 maculee and prominences on 

 the large posterior spiral portion of the genital basis.
