428 OLIGOCHAETA 



of sperm-ducts (and testes /) tingle. Spermiducal glands UK in XVII-XIX, with small 

 terminal sac. Hob. Viti. 



This species appears to be quite distinct on account of the possession of only one 

 pair of funnels ; but as I had only a single specimen at my disposal, which forms part 

 of the collection in the Vienna Museum, I was naturally obliged to dissect it with 

 great care. It is therefore possible that an error has been made in this particular, 

 as the possession of two pairs of funnels and testes appears to be one of the marked 

 characters of the Perichaetidae. I suggested that this species may, perhaps, be the 

 same as GRUBE'S P. subquadrangula, which comes from the same locality. But 

 GRUBE'S description is not sufficient to enable me to decide the point. 



(61) Perichaeta everetti (NEW SPECIES). 



Definition. Length, about 300 mm. ; diameter, \zmrn.; number of segments, 190. Clitel/iin/, 

 XIV-XVI, without setae. Male pores separated by sixteen setae. On each of segments 

 XIX-XXI a pair of long narrow papillae just in front of line of setae. Their length 

 is equivalent to about eight setae, and they are separated (the pair of each segment) by 

 about an equal number. Dorsal pores commence XII/XIII. Gizzard in VIII. Septa 

 II '/ 1 VIII, XI/XIV thickened. No caeca. Last hearts in XIII. Spermathecae in VI / 

 VII; twelve and seventeen respectively; the number of the diverticula appears to 

 correspond. Hob. Mount Kina Balu. 



This species is very near to P. stelleri. They may prove to be identical. In 

 the meantime the number of spermathecae is different, and the genital papillae seem 

 to be rather different. The present species has a reddish purple colour dorsally; the 

 egg-sacs (in segment xiv) are very large ; a pair of sacs in xiii close to ovaries may 

 be a second pair. 



(62) Perichaeta papillata (NEW SPECIES). 



Definition. Length, 500 mm. ; diameter, 7 mm. Clitellum, XIV XVI, without setae. Male 



pores separated by ten setae ; on each of ten following segments a pair of papillae in 



front of line of :-etae ; closer to middle line than male pores. Dorsal pores commence 



XII/XIII. Septa iV/VIH, IX/XIII thickened. Caeca absent. Last hearts in XII. 



Spermathecae in VI, VII ; seven in each segment; each lias a small coiled diverticulum 



ending in an oval sac. Sperm-sacs in XI, XII ; egg-sacs in XIII. Spermiducal glands 



extend through three segments, without terminal muscular sac. Hab. Mtrabah, N. 



Borneo. 



The length of this species is probably not natural ; it was much softened. 1
