90. ADDITIONS TO THE TAsMANUN MA KINK MOLLU8I \. 



EULIMA MAMILLA, Sp. Nov. 



Shell very minute, white, shining, pyramidal. Whorls 

 4Ad, rapidly increasing; apex inammillated ; mouth broadly 

 pyriform ; lip anteriorly expanded ; umbilical area mode- 

 rately excavated. 



Length 1.4. Breadth 0.5 mill. 



Type, 50-70 fathoms, off Port Arthur, with one other. 

 Another from 40 fathoms, off Schouten Island. An ex- 

 tremely minute Eulima, but easily recognisable, the 

 swollen apex being a good distinguishing feature. 



PI. III., fig. 17. 



EULIMA CUN^sEORMIS, Sp. Nov. 



Shell yellowish-white, highly polished, narrowly pyra- 

 midal, slightly curved, apex blunt. "Whorls 8, slightly 

 rounded, suture distinct, the base of the preceding whorl 

 showing clearly through the shell ; body whorl tumidly 

 developed. Mouth small, pyriform, umbilical area broadly 

 excavate. 



Length 4. Breadth 1.5 mill. 



Type, with one other, from 50 fathoms, off Maria Island. 

 Two, from 50-70 fathoms, off Port Arthur, and four, from 

 40 fathoms, off Schouten Island. A species without very 

 marked characters, but which I cannot unite with any 

 other known to me. Apex further enlarged. 



PI. III., fig. IS, shell, fig. 18a. 



ODOSTOMIA OCCULTIDENS, Sp. Nov. 



Shell minute, white, translucent, shining, smooth. 

 Whorls three, plus a prominent heterostrophe pullus. 

 Adult whorls rounded, regularly increasing. Aperture 

 ovately-pyriform. Columella arched, thin, with a minute 

 plication, rather above the centre, which is invisible from 

 a front view. 



Length 1.5. Breadth 1 mill. 



Tvpe, with several others, from 100 fathoms. 7 miles 

 east of Cape Pillar; also from other localities, from 10 to 

 50 fathoms. A very variable species in some particulars. 

 The shape is usually fairly constant, although it is some 

 times a little longer than the type, and it scarcely varies 

 in size. It may have no plait at all, or it may be fairly 

 well developed. The pullus may be prominent as figured 

 or quite immersed. I have tried to separate it into two 

 Bpeciee, but all the forms seern to intergrade.
