MEGASCOLEX SUMATRANUS 189 



connected with the other by a long, narrow tube. It must 

 be mentioned that in several specimens (from Soepajang) I 

 found another tube joined with the efferent duct of the small 

 vesicle, nearly in the middle of its length, the copulatory 

 pouch being thus here composed of three parts. However 

 this difference seems not to be of great value, because this 

 second tube shows different degrees of development, and 

 has often only the shape of a small caecum. 



The testicular sacs, consisting of four lobes, are placed 

 in the 11th and 12th segment; from each lobe a tube 

 issues beginning with a funnel-form mouth. On a small 

 distance from their origin the two tubes on each side of 

 the body are uniting in a single vas deferens. This vas 

 deferens joins the muscular duct of a prostatic gland , 

 which opens in the male genital orifice. 



Length of the largest specimen 120 m.m. ; number of 

 segments 100.

Probably some of the specimens of P. cingulata , examined 

 by Vaillant , are identical with M. indicus ; however Vaillant, 

 as stated by Perrier, having confounded different species 

 under this name , and moreover Schmarda's description of 

 P. cingulata being too incomplete to make recognition of 

 this species possible, I think it more desirable to cancell 

 that name.

The copulatory pouches opening by two pair ofslitsha- 

 ped pores at the ventral side between the 7th and 8th, 

 and the 8th and 9th segment. The male genital orifices 

 situated on the 18th segment are surrounded by a plicated 

 wall. The opening of the oviduct is very indistinct. The 

 number of setae on each segment amounts to 38 ; only 

 on the cincture they are wanting. Like in the preceding 

 species there are to be found tubular spirally wound glands on 

 the anterior side of the 6th and 7th septum. The mus- 

 cular stomach is situated in the 9th and 10th segment;
