DESCRIPTIONS OF GENERA AND SPECIES 429 



observed two distinct oviducal pores opening upon the common area. On the 

 clitellum there are three lines marking the place where the setae should be. It is 

 probably not a matter of much importance, but the spermatheca were arranged thus, 

 VI, 3-4; VI, 4-3- 



(63) Perichaeta sarawacensis (new species). 



Definition. Length about 300 mm. ; diameter, 7 mm. ; number of segments, 260. Clitellum, 

 XIV-XVI, without setae. Male pores followed by four pairs of papillae on following 

 segments. Dorsal pores commence XII/XIII. Caeca absent. Septa V/VIII, J/XIV, 

 thickened. Last pair of hearts in XIII. Spermathecae in VI, VII, about fourteen in 

 each with diverticula as in P. everetti. Sperm-sacs in X, XI, XII; egg-sacs in XIII. 

 Spermiducal glands rather diffuse extending through three segments. Hab. — Sarawak. 

 This species does not show the purple colouration of its allies. It is apparently 



intermediate between P. everetti and P. papiUata. The papillae are like those of 



the latter though not so numerous ; the internal structure is more like that of 



P. everetti. 



(64) Perichaeta kinabaluensis (new species). 



Definition. Length, 150 mm. ; diameter, 9 mm. ; number of segments, 300. Clitellum, 

 XIV— XVI, without setae. Male pores separated by sixteen setae; on XIX and XX 

 a single median papillae, like those of P. everetti fused ; on XXI the left half only 

 developed. Dorsal pores commence XI/XII. Gizzard in VIII ; no caeca. Septa 

 V/VIII, X/XIV thickened. No septum missing. Last hearts in XII. Spermathecae 

 in VI, VII ; eleven and seventeen in each ; the diverticula as in P. everetti. Sperm-sacs 

 in X, XI, XII. Egg-sacs in XIII. Spermiducal glands large and compact though 

 limited to one segment, the septa of which are bulged out to make room for it ; without 

 terminal muscular sac. Hab. — Tamburungare, Kina Balu, Borneo, at an altitude of 

 7,700 /if. 

 This species comes nearest to P. everetti. It has (in spirit) the same purple red 



colour above with white lines where the setae are unplanted. A few slight 



differences will be recognizable from the above description. 



{65) Perichaeta upoluensis, Beddaed. 

 p. upoluensis, Beddaed, P. R. Soc. Edin., vol. xiv, 1886, p. 174. 



Definition. Length, about five inches. Clitellum XIV, XV. Genital papillae one on each 

 of segments IX, XVI-XX; on XVIII in addition a pair of papillae to inside of male
