COLLECTED IN DUTCH NEW GUINEA. 495 



Setae in continuous rings : 45 setae on segment iv., 50-60 on segments x. to xxvi. 



First dorsal pore in inter-segmental furrow xiii./xiv. 



Clitellura embracing entirely segments xiv. to xvi. ; it has no setse. 



Male pores near the middle ventral line ; the interval between these pores corresponds 

 to y of the segmental circumference, and bears no setae. The bursfe. copulatrices are 

 partially extruded as a wrinkled swollen margin around each male pore. 



Female pore is a short transverse fissure on segment xiv. 



Two pairs of spermathecal pores in the inter-segmental farrows vi./vii. and Vll./viii., 

 in line with the male pores. Between these lines are present seven setae on seg- 

 ment viii. The lips of the spermathecal pores are slightly swollen. 



Internal Anatomy. — Dissepiments iv./v. to vii./viii. and x./xi. to xii./xni. moderately 

 thickened; the septa Vdi./ix. and ix./x. are absent. 



A strong gizzard is present in segments viii. and ix. The sacculated intestine 

 begins in segment xvi. ; its lateral caeca are simple, and extend from segment xxvL to 

 xxiir. 



Hearts paired in segments x.— xiii. 



The seminal capsules are paired in segments x. and xi. ; the two capsules of the 

 same side communicate with each other through septum x./xi. The two capsules ot 

 the same pair do not seem to be in communication ; if a communication is present, it 

 may be limited to a narrow intraseptal lacuna. 



The seminal sacs are paired in segments xt. and xii., the two pairs being of equal 

 size. Each sac is provided with an apical finger-shaped appendix. A pair of 

 rudimentary sacs is present in segment xiii. 



The ovaries lie in segment xui. and a pair of egg-sacs in segment xiv. 



The spermiducal glands are very like those of Pheretima, {Parapheretima) hellwigiana 

 Cogn.*. The glandular portion is slightly lobulated and occupies the two segments 

 XVII. and XVIU. The muscular duct is moderately thin and strongly bent; it opens 

 in a little bursa copulatrix, which is partially extruded. In the bursa there also opens 

 a tubular and strong-walled gland, which extends backwards from segment xviri. to 

 about segment xxiii. The surface of this gland is provided with lobules, which very 

 probably are due to the cysts of Gregarines. 



There are two pairs of spermathecae in segments vii. and viii. The muscular duct 

 and the pear-shaped main pouch are of equal thickness, but the pouch is shorter 

 than the duct. The duct is covered with villous glandular appendages, and is 

 provided with a short stalked diverticulum in the middle line ; the length of 

 the diverticulum is less than that of the duct (text-fig. 41, B).
