nneimost of all; this increases in size, and forms a more compact 

 coil than the dorsally situated nephrrdia of the row, though it is 

 not so elongated in a transverse direction as these. 



The testes and male funnels are free in segments x and xi. 

 Seminal vesicles occupy segments ix and xii, those in the latter 

 segment being large, contiguous in the middle line dorsally, and 

 slight!}' bulging back septum 12/13 .' the pair in ix are slightly, 

 those in xii considerably lobed. 



The prostates are tubular, of moderate size, closely coiled, and 

 cause the septa bounding segment xviii to bulge apart somewhat. 

 The duct is much narrower than the glandular part, is bent on 

 itself, short, slightly shining, the ectal part wider than the rest. 



Ovaries and female funnels are present in segment xiii. 



The spermathecae (fig. 9) are one pair only, in segment viii. 

 The ampulla is moderatelj' large, of an inverted pear-shape, and 

 marked by a number of slight annulations. The duct is short, 

 one-thiid to a quarter of the length of the ampulla, bulged in its 

 upper portion, narrowed at its ectal end, with a row of four or 

 five small seminal chambers on its inner side which take up the 

 greater part of its length. 



The penial setae are apparently two in each bundle. In 

 length they are '66 mm. ; in form tapering, slightly bowed, the 

 curve more marked towards the distal end, the tip slightly hooked 

 and rounded ; there is no ornamentation except a few very fine 

 transverse markings or slight notches on the distal portion a 

 little distance from the tip, — so slight that they might be accidental. 



Remarks. — The nearest ally of the present form appears to 

 be M. duodecimalis , from Parambikulam ; but the presence of only 

 one pair of spermathecae distinguishes the present species. The 

 penial setae, and the curious row of seminal chambers sessile on 

 the spermathecal duct, are also characteristic.
