on each side of the nerve cord, and are very large in the first five 

 segments. Probably owing to excessive contraction in my 

 specimens their apertures are not visible on the exterior.

The worms of this species are chiefly characterised as follows :- — 

 Body of from 350 to 500 segments, about 2 feet long when 

 contracted and about 6 feet long when extended, setae difficult to 

 see, arranged in eight longitudinal rows of four pairs, clitellum 

 incomplete, consisting of three short ventral bands between the 

 32nd, 33rd, and 34th segments, position of male and female 

 genital pores undetermined. 



From these characters it would appear as if these worms might be 

 anteclitellian, but though this is a point which can only be settled 

 by dissection, I venture to express the opinion that on further 

 examination they will probably be found to be intraclitellian, and 

 that the clitellum may be better developed in the breeding season. 



Hab. — Gippsland, Victoria (McCoy). 



In conclusion I have to thank several gentlemen for their 

 kindness and help, or for specimens, among whom I am particularly 

 indebted to my late colleague, Mr. B. T. Baker, for the first 

 specimens of Notoscolex grandis I obtained, and for his kindness 

 in making a number of careful drawings of various worms ; to 

 Mr. J. D. Cox for the opportunity ot visiting Mt. Wilson ; to 

 Messrs. Garland, Hamilton, and Mitchell for specimens of Lum- 

 bricus NovcE-Hollandioz from their respective localities ; to Mr. 

 Masters for the best specimens of L. olidus that I have seen; 

 and to Mr. Haswell for the loan of several important papers, 

 which I should otherwise have been unable to see.
