Anterior male organs: Two pairs of tuft-shaped testes and two pairs 

 of much folded sperm-duct-funnels in segments lo and ii, apparently embedded in 

 free sperm masses. The testes and sperm-duct-funnels of the anterior pair in the loth 

 segment are very much smaller than those of the posterior pair in the nth segment, 

 but are by no means rudimentary. The sperm-ducts are relatively very thick; those of 

 one side seem to unite not before having reached the 17th segment. Two pairs of sperm- 

 sacs depend from septum 9-10 forwards, from septum 11-12 backwards. They are 

 broad and much incised, those of the anterior pair short, confined to the 9th segment, 

 those of the posterior pair longer, extending through several segments as far as into 

 the 30th segment. 



Prostates tubular; glandular part long, coiled, and pressed together to form 

 a rather compact mass, occupying about three segments ; muscular duct thin, very 

 much shorter, somewhat bent. 



Penial setae missing, but some stout transverse muscles present. 



The distal end of the sperm-ducts, whichare relatively very thick throughout 

 their length, is provided with a pear-shaped muscular coat, which is about twice as 

 thick in the thickest portion as the other parts of the sperm-ducts. The two sperm- 

 ducts of one side unite just before going over into this muscular coat; then they pass 

 the distal end of the prostates laterally and, turning round it, open from behind into 

 the same pore with them. The lumina of the sperm-ducts and of the prostates unite 

 in the thickness of the body- wall just before reaching its outer surface. 



Spermathecse: Main pouch consisting of a nearly circular, sometimes some- 

 what depressed and shortened ampulla, which opens through a short, conical duct ; 

 into this duct open a great number (about 10) of stump-like diverticula of different 

 sizes, generally somewhat longer than thick and distally hardly, if at all, narrowed. 

 Sometimes two of these diverticula are united at the base. They contain a single 

 sperm chamber, v\^hich, however, is not quite simple, the walls of the diverticula being 

 partly thickened to form transverse ridges depending into the lumen and narrowing it. 

 The diverticula surround the duct of the main pouch in a rosette-like manner, forming 

 sometimes a nearly complete circle round it. In other specimens the circle of diverti- 

 cula is more or less shortly interrupted at two points, these interruptions dividing the 

 whole number of diverticula into two groups. The diverticula are in situ nearly 

 hidden beneath the ampulla, only the proximal ends of some larger ones projecting 

 over the edge of the ampulla.

I examined one mature specimen somewhat larger than the largest specimen ex- 

 mined by BEDDARD. My specimen showed the following features : —
