Description of Vic'orian Earthworms. 137 



Accessory copulatory structures. Two small glan<l\ilar 

 patches on segment 17, at the level of the intervals between 

 the inner rows of set?e, and a median ventral patch on the 

 anterior margin of segment 18. 



Dorsal pores present, the first between segments -5 and (5. 

 Nephridiopores conspicuous, commencing on the second 

 segment, and placed on each side anteriorly to, and at the 

 level of, sette 1 , 3 and 4. 



Alimentary canal. Gizzard in segment 5. Vascular 

 swellings on the oesophagus in segments 12, 13 and 14. 

 True calciferous glands well developed in segments 15 and 

 16. Large intestine commencing in segment 18. 



Excietory system. Meganephric (?) with three coiled 

 tubes on each side in each segment, corresponding to the 

 nephi-idiopores. (The nephridia of this form are very 

 interesting and probaljlj^ indicate an aggregation of plecto- 

 nephric tubules into three groups). 



Reproductive system. Testes doubtful. One pair present, 

 liut small, in segment 10, attached to the anterior wall ; 

 probably a pair in segment 11. Ciliated rosettes distinct 

 in segments 10 and 11. 



Prostates double. A smaller anterior coiled tubular mass 

 in segments 17 and 18 ; a posterior' larger mass in segments 

 18-21. Separate duct from each, the two uniting together 

 and having a single opening in segment 18. 



Sperm sacs in segments 11 and 12. Each has the form of 

 a saccular dilatation attached to the anterior wall of the 

 segment. The anterior one probably encloses a testis. 



Ovaries in segment 13. Oviducts opening into the same 

 segment. 



Spermathecse, two pairs. Each consists of a long sac, with 

 two short club-shaped diverticula arising from the duct. 



Habitat. Victoria. This j)robably comes from Croajingo- 

 long but the distinct locality other than Victoria is not noted. 

 It is evidently closely allied to C. fastigatus, Fl., but is 

 distinct from this (1) in the possession of well developed 

 calciferous glands in segments 15 and 16, and (2) in the 

 sperm sacs not being racemose. The curious double nature 

 of the prostates, and the identical arrangement of the neph- 

 ridia shows the two forms to be closely allied, but at present, 

 pending the publication of our full report, they are placed as 

 distinct species in the genus Cryptodrilus.
