PHILINE ANTARCTICA. 



(PI. XXIV., fig. 1.) 



Testa magna, semiconvoluta, tenuis, alba, periostraco tenuissimo nitente induta, 

 lineis increnienti conspicuis sculpta; sjiira involuta, depressa, excavata ; 

 anfractus 2-3, iiltinius maximiis, antice latior qiiam su[)ra, callo lato tenui 

 parietal! amictus ; apertura svibpiriformis, longit. totam aequans ; coluniella 

 cariniformis, spiralis, usque ad apiceni intus jierspicua. 



Longit. 29 mm., diiim. maj. 21 mm. 



Habitat. — Cape Adare, 20 fathoms. 



A fine species, not unlike Scaphander lif/najnvs in form. More 

 convolute than usual and consequently with a more contracted 

 aperture. The periostracum is peculiarly shining, having a some- 

 what metallic look. The cephalic disc is oblong, rounded in front, 

 widening behind, where it is slightly notched in the middle. The 

 foot is about the same length as the head-disc, but broader. The 

 mantle investing the shell is thickened into a ridge around the spire 

 and forms a blunt end to the animal. Only a single specimen was 

 obtained, 



PHILINE APERTISSIMA. 



(I>1. XXIV., tigs. 2, 3.) 



Testa compressa, ovata, tenuis, alba, periostraco tenui pallido induta, lineis increment! 

 valde curvatis striata; s])ira nulla, involuta, excavata; apertura latissima, 

 longitudinem totam aequans ; columella cariniformis, spiralis, intus usque ad 

 apicem perspicua, callo lato parietali tenui superne labro juncta. 



Longit. 11^ mm., diam. maj. 9 mm. 



Habitat. — Cape Adare, 24 fathoms. 



Much smaller than P. antarctica, with a more patulate aperture 

 and less convoluted. Four specimens were collected.
