and extends inwards a little beyond b (internal to b) ; the centre 

 of the slit is thus between b and c, slightly nearer to b. 



The genital markings are characteristic (fig. 12). On the 

 ventral surface of segment xvi behind the setae, is an unpaired 

 shallow V shaped depression, the legs of the V being wide apart, 

 and rather broadened at their anterior, separated, ends. In these 

 swollen ends small rounded papillae are present, projecting suffi- 

 ciently to reach the level of the general surface : these anterior 

 broadened ends of the V are situated just behind the setae ab on 

 each side. 



There are also three pairs of rather indistinct eyelike markings 

 in furrows 51, U and It, transversely oval, with their centres in or 

 just internal to b, extending inwards to a and outwards to a 

 corresponding distance on the other side of b. 



Septa i and « are stout and muscular ; 7 and | are absent ; 

 I, To and i'f are all thick and placed close together ; ii is absent as 

 a septum, being represented by a mass of connective tissue 

 between the seminal vesicle and intestine, which binds down the 

 heart of segment xi ; the rest of the septa are thin. 



The oesophagus is moderately broad behind the pharynx and 

 in front of septum :', narrow between ^ and « : it is again wider in 

 the anterior part of the space between i; and 77, where it is situated 

 between the spermathecae ; this portion is followed by a compara- 

 tively small subglobular gizzard. The rest of the oesophagus is 

 narrow, except in segment xii where it is slightly dilated. This 

 dilatation corresponds to the calciferous glands of some of the 

 other species of the genus ; on opening the tube an elongated mass 

 is seen to project on each side into the lumen of the oesophagus 

 from its lateral and ventral wall ; a narrow vertical cleft is left 

 between them in the middle line, and a continuous pas age above 

 them, between the projecting masses and the dorsal oesophageal 

 wall, so that in transverse section the lumen of the tube here 

 appears T-shaped ; calcareous particles occur in the oesophagus in 

 this region, dorsal to the projecting masses i.e. in the cross limbs 

 of the T. 



The intestine begins in segment xv. 



The circulatory system resembles that of E. ualtoni. The 

 dorsal vessel ends anteriorly by dividing to form the lateral com- 

 missures of segment vii ; the last heait is in s gment xiii. 



The excretory system is micronephric ; tufts of micronephri- 

 dia are present one on each side anteriorly b}^ the sides of the 

 pharynx ; behind this they are irregularly scat^-ered as far as seg- 

 ment xii, but beyond this point they are arranged in transverse 

 lines in each segment. 



The testes were not identified. There is a single pair of large, 

 folded, iridescent funnels in segment xi, touching each other in the 

 middle line, and contained in a common sac continous from side to 

 side beneath the alimentary canal. The vesiculae seminales, a 

 single pair, are flattened against the sides of the alimentary canal, 

 and are deeply lobed ; they are doubtless to be considered as
