a little narrower than tlie flat intervening sulci ; lir?e about ten 

 to twelve on the penultimate whorl. 



Last whorl sub-quad rately rounded, sliortly and Ijroadly attenu- 

 ated at the base ; equi-distantly Urate, with a thread and a few 

 strife in the interstitial sjiaces, obscurely marked with sigmoidal 

 transverse stritv. 



Aperture quadrately oval ; outer lip much thickened ; siphonal 

 notch very short and narrow, not interrupting the outer rim of 

 the lip. 



Dimensions. — Length, 15-5; breadth, 12; length of aperture, 9. 



Locality. — Jemmy's Point, Gippsland Lakes ( W. H. Greyson !) 



The well-rounded whorls, not sulcated at the suture, and the 

 simple lirate sculpture distinguish this sjDecies from all known 

 congeneric forms either recent or fossil ; this is the first record of 

 the genus as a constituent of the Cainozoic fauna of Australia. 



Genus Pelicaria. 



Of this genus, allied to StruthioJaria, having its head-quarters 

 in the seas of New Zealand, only two species are known, namely, 

 P. scutulata (Martyn), which inhabits the coast of IsTew South 

 Wales, and *S'. mirabilis (Smith), of the Kerguelen Islands. 

 Pelicaria differs from Struthiolaria, chiefly in the enamel-covered 

 spire of the adult shell, and the thin sinuous outer lip. The two 

 fossil species, now to be described, do not differ in any striking- 

 manner from P. scutulata, but both are less turreted. 



SYNOPSIS OF SPECIES.

Shell ovate, spire acuminated, whorls six convex, suture linear 

 or slightly impressed. Surface ornamented with numerous lamel- 

 liform rugfe, becoming confluent by twos and threes or more at 

 the anterior-third to form ridges, and by spiral threads abont ten 

 in number. Last whorl quadrate, depressed in the medial part, 

 with a row of small acute nodulations at the shoulder, and a 

 thickened ridge at the periphery ; ornamented with sigmoidal 

 lamelliform ruga? and lines of growth which are cancellated by 

 numerous longitudinal ridges. Callus-enamel spreading over 

 the columella and body-whorl for two-thirds of its length and 

 over-lapping on the penultimate whorl.
