272 RECOKDS OF THIi At'STKALIAN MDSEDM. 



A specimen from Toi'res Straits, thus doubtfully determiued from 

 literature and here figured, is immature and small, being 8'5 mm. long 

 and 4 mm. broad, biconical, densely encircled by spiral threads, of which 

 there are about forty on the last whorl. There ai'e about nineteen radials 

 projecting as tubercles along the angle of the shoulder, but faint above 

 and below. On the earlier whorls the shoulder nodules are proportionately 

 more prominent. The whole surface has. a secondary sculpture of close 

 microscopic I'adial threads. Whorls seven, including a small smooth 

 protoconch of two helicoid whorls. Apertui'e incomplete, but commencing 

 to form a varix and mounting on the preceding whorl. Cithara matakuana 

 Smiths* lias a general resemblance, but has fewer and coarser radials.
