896 MR. F. E. BEDDARD ON THE [Dec. 4, 



From the foregoing account of its structure may be abstracted 

 the following brief definition of 



Amyntas virgo, n. sp. 



Length 152 mm. Setae of anterior segments rather larger. 

 Clitel 1 um xiv.-xvi., without seta?. Male pores far apart. No 

 genital papilla?. Gizzard-septa wanting. Caeca present. Last 

 hearts in xiii. Sperm-sacs small, in xi., xii. Spermiducal glands 

 confined to xviiith segment, with circular terminal sac. Sperma- 

 thecse Aery minute in vii., viii., ix., with equal-sized diverticulum. 



I/ah. Malay Peninsula. 



(7) Amyntas perichaeta, n. sp. 



Although I have had for examination only a single example of 

 this species, there is no possible doubt, in my opinion, of its 

 distinctness as a species. It furnishes, moreover, an excellent 

 example of how necessary it is to dissect an earthworm merely for 

 the purpose of discovering whether it is known or not described. 

 Externally, the present species might readily be confounded with 

 many others. But its somewhat negative external characters 

 combined with several internal features of very positive value 

 enable it to be placed with accuracy. 



It is a stoutish worm of 170 mm. in length. 



The number of segments is 116. 



The setce are more or less equal in size ; those of the anterior 

 segments show no special differentiation. 



I could find no genital papilla of any kind. 



The elitellum occupies the usual segments and is quite free 

 from seta?. 



The male pores are conspicuous orifices separated from each 

 other by a fairly wide interval. 



The gizzard-septa appear to be wauting. The intestine com- 

 mences in the xvith segment. The usual cceea of moderate length 

 are present. 



The last hearts are in segment xiii. 



The sperm-sacs lie in segments xi. and xii. ; they are fairly large 

 and solid bodies. The two sperm-ducts of each side unite very 

 shortly after they have emerged from the sperm-reservoirs. 



The spermiducal glands are on the whole very compact, although 

 they are much divided into small lobules. They occupy segments 

 xvii.-xix. and they have a kidney -like outline. Their duct is not 

 long ; it runs forward and then backward, after the very pre- 

 valent fashion, and then debouches into a fairly large terminal 

 bursa of approximately circular outline, which is confined to the 

 xviiith segment. 



A pair of small egg-sacs occur in the xivth segment, attached of 

 course to the anterior wall of that segment. 



There are three pairs of spermaihecce. These lie in segments vi., 

 vii., and viii., and are lateral in position, occupying the average 

 place that these organs occupy in the members of the genus
