 (1876), p. 28. 



Further study of tlie form I distinguished as Maryiuf^Ua kem- 

 bleusis^^ has convinced me that it is not separable from the Tas- 

 manian species, wliose name must therefore supei-sede it. 



Admete stricta, i^p. nuv. 



(Plate liv., fig. 10). 



Shell minute, thin, ovately fusiform, deeply constricted at the 

 sutures. Whorls five, ratlier tumid medially, flattened above 

 contracted at the base ; first whorl dome sliaped. Sculpture : 

 above radials predominate, below spirals prevail. The i-adials are 

 prominent undulating ribs, numbering nine on the antejxinulti- 

 mate whoi'l ; they gradually diminisli in size as growth proceeds, 

 and vanish on the base. The spirals amount to thirteen on the 

 last whorl, and seven on the penultimate, ; they consist of sharp 

 elevated cords, o\'er-riding the radial ribs and parted by flat inter- 

 stices of twice their width ; the interstices are finely, transversely 

 grooved. Aperture narrowly reniform, rounded above and below 

 outer lip sharp, colur»ella ending in a single broad fold, whence a 

 callus layer proceeds svhich overlies a narrow shallow, umbilical 

 groove. Length, 4'5 ; breadth, 1*76 mm. 



A single specimen (the type) from the present station, another 

 imperfect example from 100 fathoms, sixteen miles east of Wol- 

 longong. 



The genus Admete is now first announced from Australian 

 waters. The species is inilike any recent shell, but judging from 

 Prof. Tate's figures'^ it resembles the Tertiarj' CaiiceUaria micra 

 and C. tjirriciihda. 



Pleurotomella fastosa, sp. nov. 



(Plate Iv., fig. 21). 



Sliell small, rather solid, slender, fusiform. Whorls eight-and- 

 a-half, of which six form the protoconch. Colour •: adult whorls 

 straw yellow, protoconch cinnamon brown. Sculpture : running 

 below the suture the adult whorls have a spiral thread which 

 ascends into the protoconch for two whorls ; this is followed by a 

 broad concave fasciole, margined in turn by a sharp projecting
