laat wedervaren, maar ook een negental nieuwe soorten 
beschrijft. 
Onder deze laatsten nu komt ook de Sondarie-worm voor, 
die door hem Megascolex musicus wordt genoemd. 
Zijne beschrijving is de volgende: 
„Cephalic lobe extending nearly over the whole length of 
»the buccal segment. 
„Each segment, except those of the cingulum, with a 
„circular ridge, which carries the bristles to the number of 
»100. Orifices of the copulatory pouches between the 7" and 
8^. 8" and 9% segment. Two large slit-shaped genital 
"pores оп the 18' segment; the opening of the ovidact is a 
"small pore in the 14% segment. Between the 12% and 159 
^(or 15^ and 14%) ring we find the first dorsal pore. The 
»two pairs of copulatory pouches are situated in the 7% and 8" 
"segment: each pouch consists of two parts, a large, pear- 
"shaped vesicle with short duct, and a long tube, rolled up in 
» numerous windings. Male genital organs in the 11^ and 12% ring: 
»their vasa deferentia beginning each with two funnelshaped 
"mouths. There are two large prostatic glands, divided in 
^numerous lobes. Bunch-like ovaries in the 14! segment, 
"hanging on the posterior side of the 15% septum. The 8" 
"and 9% septum are wanting, the second copulatory pouch 
"therefore situated in the 8% as well in the 9 ring. The 
^l^, 12^ and 15% septum are extraordinarily thick and 
"muscular. Like in Megascolex Siebo/di the intestine is provided 
^on each side of the 26% segment with six caeca, of which 
»the superior is the longest; however this seems to be not a 
"Constant characteristic, in one ot the specimens only the 
"Superior caecum being present. 
"Colour: above greyish-blue , lead-coloured, underside paler : 
»ralous; girdle brownish: genital pores, mouth and vent yellowish. 
^Length 570 m. m.: eircumference of the body directly 
^behind the girdle 48 m. m.: number of segments 166. 
^Hab. Java (Конь & van HassELT, VoRDERMAN)."
