Pheretima pauaiensis sp. nov. 



Closely alike in external appearance to Pheretima orientalis 

 is a worm which I am obliged to regard as being of a new 

 species. 



It measures 70 millimeters in length and 3 to 3.5 millimeters 

 in diameter and is, therefore, of about the same size as P. orien- 

 talis and others of its allies described in the present paper. It 

 has, also, the same color and is indeed of exactly the same 

 outward appearance. 



The clitellum is of the same nature and ceases before the row 

 of setse of segment XVI. The other segments, of which it is 

 composed, also have setse upon them. The male pores are very 

 conspicuous and much like those of Pheretima sodalis. They lie 

 naturally upon segment XVIII in the line of setse and are sepa- 

 rated by about 10 setse. The external feature which makes the 

 present species particularly recall P. orientalis is the form of the 

 genital papillse. 



The genital papillEe of Pheretima pauaiensis consist of a pair 

 of apparently perfectly circular, disc-like cushions suggestive in 

 color and size of the genital papillae of P. orientalis, although very 

 different in other details as will be seen presently. The 2 papil- 

 Ise are approximated in the mid-ventral line of the body, being 

 separated by an area which is about equal to the diameter of one 

 of them. The papillae lie upon 2 segments reaching from just 

 behind the circle of setse of segment XIX to just in front of the 

 circle of setse of segment XX. They are not interrupted (that 

 is, made hour-glass shape) at the intersegmental groove. 



The internal anatomy is not very different from that of P. 

 orientalis and of its immediate allies described in the present 

 paper. 



There are 3 stoutish septa in front of the gizzard and those 

 from IX — XIII enclosing the sperm sacs are also more strongly 

 developed than those which follow. Cseca are present but not 

 very long. The last pair of hearts is in segment XII. There 

 are 3 pairs of sperm sacs in X — XII. The spermiducal glands 

 are rather large and extend through segments XVI — XX. 

 They are broken into many lobes. The duct arises at about the 

 middle of the gland and at first runs in an anterior direction ; it 

 then bends upon itself and runs backward to its orifice upon the 

 XVIIIth segment. This section of the duct is much the wider. 



The form of the spermathecse is characteristic of Pheretima 

 pauaiensis as compared with its allies hitherto described. There 

 are 5 pairs of these organs arranged in line as in the case of
