Hob. — Miriam Vale, Queensland (two specimens presented by 

 Dr. J. C. Cox to the Macleay Museum) ; Percy Island off the 

 Queensland coast in lat. 21° S. (one specimen also in the Macleay 

 Museum, collected by Mr. G. Masters during the 'Chevert' expedi- 

 tion in 1875). 



The characters of the three specimens examined agree very well 

 with Dr. Michaelsen's description based on the examination of 

 specimens from Gayndah and Peak Downs. Queensland, but have 

 the setae slightly more irregular. Michaelsen says that the third 

 and fourth rows are displaced on the last ten segments of the body, 

 whereas in the specimens examined by me the irregularity affects 

 more segments, about the last forty; also the first three pairs of 

 nephridiopores are more dorsally situated than those which follow. 

 The specimen from Percy Island is referred to in my second paper 

 p. 971 under the head of " incertce sedis ;" owing to its immature 

 and contracted condition its examination was not attended with very 

 satisfactory results. 



CrYPTODRILUS (?) UNICUS. 



Cryptodrilus tmicios, FL, P.L.S. N.S.W., 1888, III., (2), p. 1540. 



Three additional specimens from a new locality ; 63 (juv.) to 

 100 mm. long, 3- 6 mm. broad; number of segments 126-144. 



Cliteilum in two of the specimens comprising segments xiv-xvii 

 together with at least half of xiii and of xviii. From the examina- 

 tion of these specimens, two of which are better developed than 

 any seen before, and from a re-examination of the original speci- 

 mens, my previous description may be amended as follows : — 



The rows of setae are straight and regular throughout. 



The oviduct pores are in front and just ventrad (not dorsad) of 

 the innermost setae on xiv. 



The gizzard is in segment vi. 



There is a fifth pair of vesiculae seminales on the posterior face 

 of the mesentery between xii and xiii ; the fifth pair, always the 

 smallest, are so small in non-breeding worms as to be easily over- 

 looked.
