Proc. Linn. Soc. N.S.W. (i), i88o, vol. 5, p. 45 8. 



L(j<\ — Palm Is., Queensland. 



Described from a yount,^ specimen, adult specimens beinir thicker, and the 



peristome lighter in colour. 



This uniform yellowish variet)- with a narrow sutural dark-brown band, 

 occurs also with a narrow band, at the periphery of last whorl. 



Group of blunifieldi, Cox. 



14 —T. infopmis, Mouss. 



Journ. de Conchyl., 1869, p. 59, pi. 4, fig, 3. 



Lor. — Port Mackay, Queensland. 



The largest species of the group (see note under Jra::t'ri). A l)andless 



variety occurs of a uniform dark drown with a narrow yellowish subsutural 



border. 



15 — T. blomfleldi, Cox.

= V. iran'oensi><, Hed. <Sz Musson : Proc. Linn. Soc. N.S.W. 1891, 

 p. 556, Viag. Magenta, pi, 2, fig. 5. 



L<M-. — Port Curtis, Queensland. 

 A distinct species, readily distinguished by its light-coloured earlier whorls, 

 contrasting with the very dark-brown lower ones. Under a strong lens the 

 low'er whorls are seen to have more or less obsolete, numerous spiral 

 impressed lines. 



The variety irarvoemis is the lighter-brown variety, but specimens before 

 me show various degrees between that and the darker typical colour. 



16.— T. eoneors, n. sp. 



PI. I, fig. 3. 



= jHirsoni, Pils. (not Cox) : Tryon's Man. of Conch., vol. vi., p. 162, 

 pi. 35, figs. II, 12 (not 13). 

 Shell sub-globose, solid, narrowly but deeply umbilicated, light-coloured 

 above, with two narrow indistinct light-brown spiral bands on the middle 

 whorls, last whorl of a very dark-brown, with a narrow conspicuous yellowish 

 band at the suture ; whorls 4^, last descending in front. Aperture very 

 oblique, rather dark within. Peristome moderately expanded, dark brown, 

 triangularly dilated at point of insertion and partly covering the umbilicus. 



Maj. diam. 35 ; alt 28 millim. 



Lor. — Gayndah, Queensland. 

 This species is very like blomfleldi in coloration, but more compressed in 

 form, the umbilicus is more open, and the peristome not so broadly 

 expanded. 



It is quite distinct from rurti^iana, Pfr., although bearing a superficial 

 resemblance to that species.
