poor, broken; in 300 fathoms, 5 fragments; and in 300 fath- 

 oms off Beachport, 1 poor. Taken on the beach at St. Francis 

 Island, 5 moderate. 



Obs. — This species flourishes in the medium depths, be- 

 ing not littoral, un to 50 fathoms, and then gets rare and 

 poor. One taken in Gulf St. Vincent is quite white, as is 

 one from Cowes, Victoria. 



Triphora regina, Hedley. 



Triphora rcg'ina, Hedley, Proc. Linu. Sec, New South "Wales, 

 1903 (1902), part 4. p. 608. pi. xxxii., fig. 21. Type locality— 

 Balmoral Beach, Port Jackson. 



Hedley's unique tyi^e was "mutilated at each extremity," 

 so I complete the description from a jo^rfect specimen. It 

 has a brown, elongate five-whorled protoconch, whorls con- 

 vex, faintly unicarinate in their anterior third and axially 

 finely lirate. The aperture is circular, with a rather deep, 

 narrow posterior sinus. The inner lijD is erect and solid, meet- 

 ing the edge of the basal lip, which does not cross it. Canal 

 nearly closed, reflected, uotched. It appears to be a good 

 species. 



Dredged in Gulf St. Vincent, ( ?) depth, 1 poor : in 3-5 

 fathoms off St. Francis Island, 4 poor ; in 40 fathoms off 

 Beachport, 1 perfect, 3 good ; in 45 fathoms east of North 

 Neptunes, 1 poor: in 55 fathoms off Cape Borda, 2 moderate; 

 in 62 fathoms north-west of Cape Borda, 1 poor : in 90 

 fathoms off Cape Jaffa, 1 perfect; in 110 fathoms off Beach- 

 port, 1 good ; in 130 fathoms off Cape Jaffa, 4 moderate : in 

 150 fathoms off Beachport, 4 moderate. Taken on the beach 

 at St. Francis Island, 6 moderate. This seems to be a deep- 

 water form. 



Triphora albovittata, Hedley. 



Triphora alhoviUata, Hedlev, Proc. Liun. Soc, New South 

 AVales, 1902, part 4, p. 609, pi. xxxii., figs. 26, 27. Type locality 

 — Balmoral Beach, Port Jackson. 



Dredged Gulf St. Vincent, depth unrecorded, 1 perfect; 

 in 35 fathoms, St. Francis Island, 1 poor; in 40 fathoms off 

 Beachport, 1 good ; in 55 fathoms off Cape Borda, 1 very 

 good ; in 90 fathoms off Cape Jaffa, 2 good. Taken at St. 

 Francis Island on the beach, 3 perfect, 2 good. 



Var. mamillata, var. nov. 



Instead of having the elongate four-whorled protoconch 

 of the type, it has a mamillate two-whorled apex. The first 

 whorl is round and smooth, the second has a central carina
