(11) Amyntas pulauensis, n. sp. (Fig. 5, p. 905.) 



The present species is represented by a number of specimens, all 

 of which do not show the principal diagnostic character of the 

 species, and led me to confuse it with Dr. Horst's Amyntas bosscJw-, 

 from which it appears to be perfectly distinct, provided that there 

 are no lacuna 1 in the descriptions given by Horst l and Michaelsen 2 . 



The length of the largest individual is 165 mm. ; the number of 

 segments I am unable to state with accuracy. 



The cUtellum occupies the whole of segments xiv.-xvi. and 

 appears to have no seta? upon it. 



The genital papilla are the distinguishing feature of the species 

 so far as concerns external characters. On segments xvii. and 

 xviii. in front of the line of setae is an area which presents the 

 appearance of a sieve owing to the preseuce of 40-50 pore-like 

 depressions, which are the external expression of numerous white 

 glands which are visible on dissection. These groups of papilla? 

 are median and unpaired. There appears to be a similar area 

 upon the viith, viiith, and ixth segments, which is very like that of 

 A. liilgcndorffi as figured by myself 3 . 



The male pores are very conspicuous and widely separated; 13 

 seta? lie between them. 



The gizzard-septa are absent. The intestine begins in the xvith 

 segment, and is furnished with a pair of caeca, which are rather 

 short, barely reaching to the level of the xxvth segment. 



The last pair of hearts are in segment xiii. 



The sperrn-sacs are large, solid, and compact. They lie in 

 segments xi. and xii. 



The spermiducal glands are not of a compact structure ; they 

 are much lobulated and occupy segments xvii.-xix. Their duct is 

 short and thick and opens into a rounded, rather flattened 

 terminal sac. 



The spcrmatheco' are four pairs and lie in segments vi.-ix. Each 

 sac is oval or more or less pear-shaped in outline ; its duct is 

 -harply marked off and about ^ the length of the sac. The diver- 

 ticulum is not large and not a great deal longer than the duct of the 

 spennatheca. It is divisible into an oval sperm-holding receptacle 

 and a narrower folded duct. 



Hah. Pulau, Bidang, Kelab, and Ariug. 



The following is a brief definition of 



Amyntas pulauensis, n. sp. 



Length 165 mm. Clitellum xiv.-xvi., without setae. Genital 

 papilla? mediau unpaired group of pores upon viii., ix., xvii., xviii., 

 in front of seta?. Male pores large and far apart. Septum viii./ix. 

 absent. Last heart in xiii. Ca?ca present. Sperm-sacs xi., xii.
