192 BEDDARD. 



The last hearts are in segment XII. 



The sperm reservoirs are in segments X and XI, and those of 

 each side of the body are perfectly distinct. 



The sperm sacs are in 3 pairs and are situated in segments 

 X, XI, and XII. The pair belonging to the Xlth segment is 

 the smallest. 



There seems to be a pair of minute ovisacs in segment XIII 

 lying above the very much larger ovaries. The spermathecse 

 are present to the number of 5 pairs and this is the most salient 

 internal difference of structure betvi^een the present species and 

 P. orientalis. They lie in segments V — IX, the last pair opening 

 between segments VIII/IX. The diverticulum is quite as long 

 as the spermatheca itself. It consists of a very slender duct 

 ending in a long and club-shaped sperm pouch, which has the 

 usual chalk-white appearance and doubtless, as in other Oligo- 

 chseta, is the sperm-holding apparatus. It will be noted that the 

 diverticulum is much longer than in P. orientalis and, also, rather 

 differently shaped. 



The spermiducal glands of this species are large, but not so 

 extensive as in P. orientalis. Instead of extending through fully 

 4 segments as in the last-named species, these glands extend 

 through only 3 segments in Pheretima albobrunnea. They are, 

 also, much broader in proportion to their length than are the 

 glands of P. orientalis. Each gland is divided into 3 principal 

 lobes which are again somewhat subdivided. The duct is rather 

 long and arranged in a different way from that of the last species. 

 The duct emerges from the middle of the gland and runs toward 

 the middle of the body, then bends backward, and runs parallel 

 with itself to the point of opening. The latter portion of the 

 duct is stouter than the anterior portion. There is no bursa 

 copulatrix. 



Pheretima sodalis sp. nov. 



The same bottle which contained the specimens of Pheretima 

 orientalis and P. albobrunnea contained, also, a number of 

 examples of a third species closely resembling those two in both 

 external and internal characters. Nevertheless, I believe it 

 belongs to a perfectly distinct species, differing from either P. 

 albobrunnea or P. orientalis quite as much as those differ from 

 each other. P. sodalis, indeed, is even difficult to distinguish by 

 external characters without a careful examination, for there is 

 the same lack of coloration as in its allies and the clitellum with
