of accessory copulatory organs, and also appear to carry indistinct 

 pores. In the smallest specimen none (or perliaps the anterior one 

 only) are visible. Thus two of the specimens are intraclitellian, 

 but one of the others with a not fully developed girdle is not so. 



Oviducal pores two, 2 mm. apart, on either side the median 

 line on xiv, and close to the posterior edge of the anterior 

 annulus of this segment. Spermathecal pores two pairs, opening 

 into the grooves between vii and viii and viii and ix, but situated 

 on the anterior margins of viii and ix, in line with the first row 

 of setse, ventral in position. 



Dorsal pores none ; nephridiopores not discernible. 



Alimentary canal : the buccal mass and pharynx occupy the first 

 four segments, the pharynx anteriorly and superiorly coated with 

 a glandular mass possibly salivary glands, bounded posteriorly by 

 the first recognisable mesentery between iv and v, the pharyngeal 

 muscular bands very strong and numerous, those from the latero- 

 posterior region arranged in four more or less complete circular 

 rows, and passing through the first second or third or all three 

 mesenteries to their insertions on the body walls in segments v, vi 

 or VII ; in each of the segments just mentioned is a globular 

 gizzard, the three gizzards and the pharynx connected by short 

 pieces of oesophagus ; from viii or ix to xiv the piece of intestine 

 in each segment shews a very vascular globular dilatation, 

 probably calciferous glands, though lateral diverticula seem not to 

 be separated off ; the large intestine commences suddenly in xvi, 

 and though of larger calibre than the preceding portion, part 

 of it being coiled in cork-screw fashion, this appears at first sight 

 in a contracted worm to be much greater than it really is ; 

 unprovided with caeca. 



Genitalia : two pairsof racemose testes (in the specimen dissected 

 5 mm. long, by 1-5 wide) the anterior pair in ix attached to the 

 anterior surface of the mesentery between ix and x, the posterior 

 pair in xii attached to the posterior surface of the mesentery between 

 XI and xii, those of each pair quite independent of each other, one
