NOTES ON AUSTRALIAN EARTHWORMS, 
I have no doubt this is also the case in C. mediterreus^ but in 
the specimens of that species dissected by me, I was unable to see 
the connection. 
Rah. — Forbes, X.S.W. ; from the banks of the Lachlan River 
(collected by Mr. H. J. Fletcher). 
This species is allied to C. mediterreus, but of the latter indi- 
viduals have the body less robust and with fewer segments, are 
without the dorsal grooving, while the characters of the vesiculse 
and spermathecse are noticeably different. 
Cryptodrilus Sloanei, n.sp. 
Four moderately contracted spirit specimens 52-71 mm. long, 
5mm. broad; number of segments 135-150; a fifth doubtful 
specimen (juv.) 35 x 3 mm., number of segments 180. 
Colour pallid (the specimens somewhat bleached perhaps). 
Prostomium divides the buccal ring almost completely. 
Clitellum not developed or indicated in any way in any of the 
specimens. 
Male pores on conspicuous papillte on xviii, the pores opposite 
the second setm, the papillm extending some little way on each 
side. Three pairs of spermathecal pores opposite the second setse. 
Alimentary canal : three pairs calciferous pouches in xi-xiii 
more or less underlying the canal. 
Genitalia ; vesiculse seminales in ix and xii. Spermathecse 
three pairs, each of them with two caeca. 
Last pair of hearts in xill. 
This species is allied to C. mediterreus and C. canaliculatus. 
From the former it differs (1) in the prostomium dividing 
the buccal ring more or less completely, (2) in having the 
vesiculae seminales in ix and xii, and not in consecutive 
segments, and (3) in the spermathecae having each two caeca. 
From the latter it differs in the body having fewer segments, and 
not being canaliculate, and — as far as I know at present — in the 
absence of anything like accessory genital papillae. In all three
