Chcetce : when viewed from above, both c and d are on the 

 dorsal surface, and c is well above the lateral margin.

The clitellum is fully developed, complete, and includes seg- 

 ments 14 to 17 ; but both the 13th and 18th segments are 

 glandular on the dorsal surface, the furrows 13/14 and 17/18 

 are, however, quite deep, whereas the intervening ones are 

 obliterated. 



Genital pores^ <L-c. (text-fig. 73). — In segment 18 is a slight 

 circular depression with raised margin, in line with the gap ab ; 

 the chfeta a appears to be absent. There is a single median, oval 

 titberculum jjubertatis on the hinder margin of the 18th segment, 

 extending from a-a. 



The three pairs of spermathecal pores are on the hinder 

 margins of segments 6, 7, 8, in the gap ab, though nearer to a 

 than to b. 



Internal Anatoiny. 



There are seven thickish septa beliind segments 7-13. 

 The last heart is in segment 12.

Text-fig. 74. ToTcea huttoni.—Y iew of the prostates, wliicli, though sj-m metrical, 

 have assumed a reversed position (? abnormal), with the anterior end directed 

 forwards. N.C., nerve-cord.

 specimen). 



The gizzard is long, narrow, and the w^all rather thin. 



The micronephridia form a pretty close felt over the body-wall, 

 and commence (as in other sjiecies) in segment 3. 



The prostates (text-fig. 74) are shorter than in either of the 

 preceding species, and both are directed forwards, but lie side by
