378 NOTES ON AUSTRALIAN EARTHWORMS, 



Tlie remaining two species are postclitellian, with eight rows of 

 setae. One from the Hunter and Ilawkesbury districts is a 

 new type for which is established the new genus Ferissogaster, 

 characterised by the presence of three gizzards, but it differs 

 fundamentally from Benham's recently instituted genus Trigaster 

 in the characters of the generative organs. 



The other species is an interesting little worm I have recently 

 found at Mt. Wilson, in which I have as yet been unable to find 

 either gizzard or spermathecse. As I wish to avoid multiplying 

 genera 1 provisionally refer it to the genus Gryptodrilus, which 

 at present consists of a somewhat heterogeneous collection of 

 species whose common characters so far appear to be that they are 

 postclitellian ; have eight rows of setse, not in pairs, and frequently 

 at considerable intervals apart ; a single (or no) gizzard : and 

 that they have the male pores opening on the eighteenth 

 segment. 



I have to acknowledge the valuable assistance I have received in 

 various quarters. For entirely new material, or for the oppor- 

 tunity of obtaining it I have especially to thank Mrs. "Windeyer 

 of Raymond Terrace, the Hon. W. Macleay, Kev. K. A. Corner, 

 Mr, J. D. Cox, Mr. A. G. Hamilton, Professor Rennie, Dr. E. C. 

 Stirling, Dr. E. P. Ramsay, Mr. Masters, and Mr. T. G. Sloane. Not 

 less am I indebted to Mr. J, D. Ogilby, Mr. Whitelegge, and 

 several other gentlemen for specimens of worms which, though not 

 new, were from new localities. 



EUDRILUS (1) DUBIUS, n. Sp. 



The largest (moderately contracted spirit) specimens measure 

 60 to 65 mm. long, 4 mm. broad, and comprise about 110 segments ; 

 several smaller specimens comprising about 85 segments are about 

 45 mm. long. 



Colour pallid, except where as at the anterior extremity and in 

 the dorsal region the bloodvessels showing through the thin integu- 

 ment give a red tinge ; clitellum of a yellow hue.
