Fig. 27. 



Eutyphoeus nainia- 

 nus. 



Copulatory organs: One transversely oval area, ventral median in the 

 intersegmental furrow 16-17, laterally hardly surpassing the lines of 

 setae a ; the area is surrounded by a whitish wall and is divided into 

 two symmetrical parts by a siniilar longitudinal wall in the ventral 

 median line. 



Internal Anatomy, — Septa 4-5, 5-6, and 8-9 — lo-ii very 

 thick, 6-7 and 7-8 missing. 



Alimentary tract: A big gizzard between septa 5-6 and 8-9. 

 CEsophagus in the 12th segment swollen, containing a pair of thick 

 lateral calcif erous glands depending from the wall into the interior of 

 the oesophagus. Intestine beginning in the 14th (15th ?) segment, 

 laterally sacculated in the anterior part, with a small and simple 

 typhlosole beginning rather far behind (not before the 30th segment). 



Nephridial system micronephric. 



Anterior male organs: A pair of very large sperm-duct- 

 funnels ventrally in the nth segment, enclosed in a common seminal 

 vesicle. The lateral parts of the seminal vesicle, quite filled with the sperm-duct- 

 funnels, stretch far upwards at the side of the œsophagus. A pair of large sperm-sacs 

 depend from the hinder surface of septum 11-12 ; they are flattened and broad in 

 the anterior part, tapering backwards and, restricted by the septa, extend through a 

 great number of segments, in the examined specimen as far as the 20th segment. The 

 broader anterior part of the sperm-sacs communicates with the lower part of the 

 seminal vesicle (on one side of the specimen) or with the whole length of the lateral 

 appendix of the seminal vesicle (on the other side). A part of the large sperm-duct- 

 funnel enters the proximal part of the sperm-sacs. 



Prostates tubular. Glandular part large, coiled, occupying about four segments. 

 Muscular duct narrower, relatively long, describing a large loop extending laterally. 



There are neither penial setae nor strongly developed transverse muscles in 

 the vicinity of the prostates. 



Spermathecse (fig. 64) : Main pouch with a nearly globrdar ampulla with a very 

 short duct about half as broad as the ampulla. Into this duct open two groups of short 

 simple and nearly globular or compound diverticula, the compound ones consisting of 

 two or more united simple ones. The diverticula of the two groups form an incomplete 

 rosette interrupted at two points by interspaces of different width. In situ the 

 diverticula are nearly hidden beneath the broad ampulla.
