608 STUDIES ON AUSTRALIAN MOLLUSCA, 



rected by those having access to the types, or to go by guess, is 

 the dilemma of the student of our Triphora. Electing the latter 

 course, I note that some of Adams' species were reported with 

 corroborative detail as from Sydne3^ Assuming that these 

 species are contained in the large collection before me, I have 

 applied his names to the species which best fit the descriptions. 



The material dealt with was gathered around Sydney by the 

 late Mrs. Starkey, Messrs. J. Brazier, H. L. Kesteven and mj^self. 



I have to gratefullj^ acknowledge kind assistance from Dr. J. 

 C. Yerco, Mr. A. Morton and the Rev. H. D. Atkinson. 



This opportunity is taken of adding that the shell I described 

 from Funafuti as Triforis torquatus, Hedley, is probably identical 

 with the prior T. ustidatus, Hervier, (Journ. de Conch, xlvi., 1898, 

 p. 298, pi. xvii., f. 4), whose memoir did not reach me till my 

 account had appeared. 



Triphora regina, n.sp. 

 (Plate xxxii., fig. 21.) 



Shell narrowly conical, solid. Colour white, a narrow orange 

 line along the lowest gemmule row of each whorl and an orange 

 tip to the canal. Whorls about twelve. Sculpture : on the base 

 are three simple keels, on the last whorl three equal sized 

 gemmule rows, of which the median diminishes on the penulti- 

 mate and gradually fades away as it ascends the spire. Length 

 5 mm., breadth 1*5 mm. 



Hah. — Balmoral Beach, Middle Harbour; one specimen (self). 



Type. — To be presented to the Australian Museum. 



I venture to describe this species from a single specimen, 

 mutilated at each extremity, because the orange thread on each 

 whorl will render possible the recognition of any fragment. The 

 contour and sculpture are also sufficiently distinct from any 

 species known from this coast. 



Triphora innotabilis, n.sp. 

 (Plate xxxii., figs. 23, 24, 25.) 

 Shell small, slender and very narrow. Colour brown, gem mules 

 dull white. Whorls ten, plus a five-whorled protoconch. Sculp-
