FLAMMULI^A. 13 



(ziczac). Apical whorls most minutely spirally striated or smooth. 

 Aperture rather large, lip thin, simple, subreflexed at columella. 

 Type F. zelandice, pi. 3, fig. 29. 



Animal with narrow foot bearing a caudal mucous gland with a 

 papilla above it ; mantle slightly reflected over the peristome. 



Jaw arcuate, with flat plaits. 



Dentition : central tooth with a short mesocone, the ectocones 

 obsolete ; laterals with a short ectocone, which disappears on the 

 marginals, leaving a long, oblique mesocone only (pi. 3, fig. 27, F. 

 zelandice.*) 



Distribution New Zealand and Tasmania. The shells included by 

 Messrs Hedley and Suter in this division are rather dissimilar in 

 form. The dentition resembles Phacussa in the prominence of the 

 mesocones and obsolescence of ectocones on the marginal teeth, and 

 this peculiarity also serves to distinguish Thalassolielix from Therasia, 

 the shell of which is of similar form. Certain Tasmanian forms have 

 recently been referred by Suter to this group, a relationship 

 previously suspected by the writer.
