640 ME. F. E. BEDDAED ON THE [May 22, 



heart is in segment xii. This assemblage of characters does not 

 correspond exactly with any of the forms described by myself ; 

 nor does it fit in with any of the varieties described by Micbaelsen. 



In two individuals examined by myself and belonging to another 

 series, I find the following characters : — The papilla? three pairs 

 on xix.-xxi.; the last heart is in xii.; the sperm-sacs in x.-xiii.; the 

 spermatheeae are more numerous, in one specimen 7 and 6 in vi., 

 8 and U in vii. ; in the other 11 and 12 in vi. and 14 in vii. A third 

 individual came nearer to the first described variety in that it had 

 not more than three spermatheeae on each side of each of the seg- 

 ments vi., vii. (the actual numbers were 1-2, 3-3). There are no 

 papillae ; the last heart is in xii., the sperm-sacs in xi.-xiii. 



This form seems to come nearest to Michaelsen's variety Tclaba- 

 tensis, in which the last heart is also in xii., the spermathecse 8-11 

 pairs, but which has no papilla?. 



Another individual agreeing with the last in having three papilko 

 (those of one side of body were missing) has also sperm-sacs in 

 x.-xiii., 5 to 10 spermatheca? on each side of the body in their 

 respective segment, but has the last heart in xiii. 



Three specimens had five pairs of papillae, sperm-sacs in x.-xii. 

 or xiii., last heart in xiii., spermatheeae varying from four to twelve 

 on each side of their respective segment. In one of these there 

 were setae on the last segment of the clitellum, a feature which is 

 not present in other specimens that have been examined. This 

 group seems to agree with the variety seriata of Alichaelsen, but 

 differs in some small points. I confess that there seems to me to 

 be no way out of merging all these specimens with those I have 

 described previously and with those of Alichaelsen and Horst into 

 one species, Arayntas stelleri. But the variation in such features 

 as the position of the last heart, which is usually so well marked a 

 character, is very curious. 



This species it is quite clear comes near to the next. It is, how- 

 ever, as far as our present information goes, to be distinguished by 

 the absence of specially enlarged ventral setae. In other respects, 

 however, it is very near, and it may be necessary ultimately to 

 merge to two.
