OF NEW SOUTH WALES. 257 



The numerous stride, denticulate labrum, and scantiness of 

 callus about the siphonal notch mark the species. 



[We have two other species of the genus in N. S. Wales, both 

 distinct from this. J. E. T. W.] 



(Loc. cit. p. 238.) — Nassaria curta. 



T. parva, elongata, ovato rhomboidea, solidula, straminea, ante

It is smaller than any species in the Cuming collection and 

 has a short beak. It is like N. carduus, Reeve, but has serrate 

 delicate waves.

T. solida, ovato-conica, rudis, cinerea, plicis inconspicuis 12-14, 

 demum carentibus, et filis remotes (superne 4t) ornata ; anfr. 7,

[This appears to be only one of the many varieties to which 

 Nassa pauperata, Lamarck, is subject, to which also I am inclined 

 to refer N. Tasmanica, mihi. Angas appears to have named the 

 shell N. labecula, Zool. Proc, 1851. J. E. T. W.]
