504 STUDIES ON AUSTRALIAN MOLLUSCA, 



Mr. J. Brazier has handed to me examples of both C. angeli, 

 Ten. -Woods, and C. crebrisculptum, Tate, which he washed out 

 of sandy mud contained in an old bottle, obtained May 22nd, 

 1886, in 8 fathoms, off the Bottle and Glass Rocks, Sydney 

 Harbour. 



Elusa. subulata, A. Adams. 



Pyramidella subulata, A. Ad., Thes. Conch, ii. 1855, p. 815, 

 pi. clxxii. f. 13; P.Z.S. 1853, p. 177, pi. xx, f. 6. 



(Plate xxv., figs. 19, 20, 21.) 



Specimens of this shell dredged by Mr. J. Brazier off the 

 Queensland coast — viz., in 12 fathoms off Cape Grenville and in 

 20 fathoms off Darnley Island — add another species to the Aus- 

 tralian fauna. Beyond our limits it is reported by Tryon from 

 the Philippines, Red Sea and Japan. 



Whether it adds a genus also is a matter of opinion. Adams* 

 separated this and others from Pyramidella, as a new genus. 

 Subsequent authors have, however, held the group to be merely 

 of sectional value. Tenison- Woods reported f a Tasmanian species 

 of Elusa, but that is now unanimously considered to be a Tur- 

 bonilla. 



As the published drawings give scant details I now tender 

 others. 



Turbonilla fusca, A. Adams. 

 Tryon, Man. Conch, viii. 1886, p. 334, pi. 76, fig. 46. 



I am enabled to add this species to the fauna of New South 

 Wales on the strength of two specimens which I found at high 

 water mark in Middle Harbour. These have been compared 

 with and correspond exactly to examples from South Australia 

 whence the species was 6rst distinguished. 1
