SOWEKBY : S. AUSTRALIAN TLEUROTOMID-E. 25 



labrum acutum, obsolete crenulatum, antico leviter sinuatum, sinu 

 postico lato et profuudo. Long. 10'50, diam. 4'50mm. 



Mah. — Backstairs Passage, 16-18 fathoms (Verco). 



I have only seen three specimens of this species, of vrhich only 

 one is adult. The shell is of simple character, with the spire about 

 as long as the body-whorl, which slopes gently to the base without 

 rostrum. The lower half of the whorl is pink, spotted at the margin 

 of the zone with somewhat deeper red.

Hah. — St. Vincent's Gulf (Verco). 



A very characteristic species, marked with brown transverse lines, 

 about six on the body- whorl. The specimens vary somewhat ; the 

 type being pretty distinctly longitudinally ribbed, and the ribs raised 

 to form a crown at the augle; in other individuals the ribs are obsolete, 

 only the nodules at the angle remaining ; and one large dead specimen 

 obtained by Dr. Verco at Backstairs Passage (20 fathoms), has but 

 the very faintest sign of nodules and no trace of ribs. This last 

 • specimen measures 20 mm., and although it does not exliibit the 

 characteristic brown lines, I have, after careful comparison, no doubt 

 as to its identity. Other specimens are pure white, without lines, 

 but being dead shells 1 take them to be simply bleached, and not, as 

 one might at first sight suppose, examples of a colourless variety. 



7. Dkillia gratiosa, n.sp. PI. Ill, Fig. 1. 



Testa elongata, glabra, rufo carnea, flammis rubris latiusculis ir- 

 regularibus longitudinaliter picta ; spira producta, acuta, ad apicem 

 obtusa ; anfractus 9, leviter convexi, laeves, sutura impressa sejuncti; 

 anfractus ultimus breviusculus, leviter inflatus, basim versus contractus, 

 vix rostratus ; apertura ovalis ; columella sinuata, labrum acutum, 

 postice late et profunde sinuatum. Long. 17'50, diam. 6 mm. 



Ilah. — St. Vincent's Gulf (Verco). 



A smooth shell, pink, with longitudinal red flames ; the spire is 

 acutely elongate, but the apex blunt and papillary. 



Of this species I have only seen one adult (dead), one young (fresh) 

 specimen, and a fragment. 



8. DuiLLiA SAXEA, n.sp. PI. Ill, Fig. 4. 



Testa turrita, solida, alba; spira acutiuscula, ad apicem obtusa; 

 anfractus 6A-, convexi, obscure angulati, longitudinaliter obscure 

 plicati, aliter loeves ; anfractus ultimus spiram brevior, ad basim
