portion, a condition which possibly obtains also in the other species 

 of this group. 



In other respects so far as I know at present not differing from 

 C. mediterreus. 



Hah. — Milton, near Brisbane, Queensland (received from Mr. 

 Henry Tryon). 



This species is allied to C. mediterreus and C, canaliculatus : 

 with the former it agrees in having the body not canaliculate ; and 

 with the latter in having two caeca to each spermatheca ; while it 

 differs from both in having the body more robust (being the largest 

 specimen of a Gryptodrilus I have yet seen, with the exception of 

 C. saccariios, var., to be mentioned subsequently), the setae of the 

 outer couples further apart, and an additional pair of calciferous 

 pouches in ix. In the soft condition of the specimen examined 

 the sacs containing the penial setae are not visible, as was the case 

 with the specimens of C. canaliculatus previously examined, in 

 which species also, as I have since found, penial setae are present. 



Gryptodrilus semicinctus, n.sp. 



Four moderately contracted spirit specimens 40-54 mm. long, 

 2*5-3 mm. broad ; number of segments about 100. 



Prostomium partially divides the buccal ring (about half). Body 

 probably pallid or slightly tinged with brown or yellowish brown, 

 slender, segments mostly tri annulate. 



Setae of the outer couples a little further apart than those of the 

 inner couples which are not so close as usual, and nearly as far 

 apart as the two couples of each side ; the outermost row on each 

 side not so dorsally situated as usual. 



Clitellum of segments xiv-xvii together with half or two-thirds 

 of XIII, saddle-shaped, reaching only to about the third row of setae 

 or a little ventrad of it, not developed on the ventral surface. 



Male pores two, on papillae on the middle annulus of xviii, 

 about in line with the setae of the second row ; in front and also 

 behind but a little dorsad of each papilla is a much smaller one,
