Section Hadra Albers, 1860. 



Hadra ALB., Die Hel. (edit. Martens), p. 165, type H. bipartita. 

 Cf. SEMPER, Reisen, etc., pi. 17, f. 16, dentition of H. bipartita. 



Shell depressed with conoidal spire, narrowly umbilicated, 

 obliquely striate or hirsute ; unicolored, or brown below, yellow 

 above, never having many bands ; peristome expanded. Type T. 

 bipartita Fer. 



Dentition (of T. bipartita, pi. 32, fig. 49) similar to that of Sphce- 

 rospira, etc. ; the central and lateral teeth unicuspid, marginals 

 with an ectocone. The figure shows a central with one adjacent 

 lateral tooth, and the 47th side tooth. 



Hadra, as restricted, consists of a few north Queensland species, 

 differing somewhat from Sphssrospira in shell characters.
