Jaffa, 16 up to 15 mm. and over a hundred tips ; in 110 

 fathoms off Beachport, 1 adult and 191 up to 20 mm.; in 

 130 fathoms off Cape Jaffa, 42 up to 7 mm. ; in 150 fathoms 

 off Beachport, 17 up to 15 mm. ; in 200 fathoms off Beach- 

 port, 8 poor and small. The finest examples, as to size and 

 condition, are found in water from 15 to 25 fathoms; beyond 

 that depth, though much more abundant, they are immature 

 or smaller.

 locality — Tamar Heads, Tasmania, teste Tate and May, loc. cit. 



Dredged in 40 fathoms off Beachport, 211 of all sizes to 

 adult; in 55 fathoms off Cape Borda, 3 young fresh, 3 adult 

 perfect ; in 62 fathoms off Cape Borda, 69 quite fresh up to 

 full grown and 9 perfect adult ; in 90 fathoms off Cape 

 Jaffa, 24 good, well coloured, 32 immature; in 110 fathoms 

 off Beachport, 22 good adult, 28 immature; in 130 fathoms 

 off Cape Jaffa, 11 immature; in 150 fathoms off Beachport, 

 23 in moderate condition up to adult, 16 immature fresh; 

 in 200 fathoms off Beachport, 11 poor and immature. The 

 habitat of this species differs somewhat from that of T . runcin- 

 ata, Watson, which attains its maximum size and is abundant 

 in water from 15 to 25 fathoms. T. accisa has not been taken 

 by me at shallower depths than 40 fathoms ; it did not accom- 

 pany T. runcinata in 35 fathoms off St. Francis Island. 



Turritella circumlig-ata, n. sp. PI. xxx., figs. 3 and 4. 



Shell solid, of thirteen whorls, including a protoconch of 

 two smooth convex whorls with a prominent round apex. The 

 first three spire-whorls are smooth but for faint growth lines, 

 and are very slightly convex. The fourth has four spiral 

 cords very faintly marked, which become very stout in the 

 later whorls. The suprasutural cord, the strongest, is round 

 and projects beyond the suture, so as to imbricate the shell ; 

 the infrasutural is as wide, but not so high, and slopes from 

 the suture ; close to this cord is a much narrower and less 

 prominent one, and further removed from this and closer to 

 the suprasutural cord is another round spiral. In the last
