 Description. — -This speciea was founded on young specimens, 

 and judtrint; from the localities orifrinally indicated by Pro- 

 fessor Tate, it seems that two species have on this account been 

 confused. For the usual specimens from Muddy Creek appear to 

 me to represent quite a distinct species from that obtainable at 

 Morningion and several other localities, though I possess onei im- 

 perfect example of this species from Muddy Creek, and I there- 

 fore judge it as comparatively rare. 



Professor Tate's description runs as follows : — " Shell long, 

 fusiform with a rapidly narrowing spire of subimbricating 

 whorls, terminating in a large ovoid summit. Whorls eight, the 

 first somewhat globose, the next very narrow, smooth and 

 bicarinated, the third nearly flat, shining and spirally scratched ; 

 the other whorls gradually becoming more and more obtusely 

 angled and swollen round the anterior part, being very con- 

 tracted at the anterior suture, and flatly sloping to the posterior 

 suture ; encircled with raised threads (about 15 on the penultim- 

 ate whorl) narrower than the interspaces, which are traversed 

 by close-set striae. Last whorl tumid and rounded at the 

 periphery, rapidly contracted at the base into a long, narrow, 

 straight canal ; the surface tessellated by transverse threads 

 and stouter sjiiral lirae." 



As these particulars and the figure given agree with the fairly 

 common Mornington or Schnapper Point specimens, I intend to 

 retain the name of Clavella bulbodos for this species, but as 

 the dimensions show only young specimens a .few further re- 

 marks on the adult specimens may not be out of place. 



Shell large and strong, composed of nine rapidly enlarging 

 spire-whorls without the remarkably large mammillate embryo, 

 the spiral sculpture is distinctly developed on the first five 

 whorls, but tends to become obsolete on the penultimate and 

 body whorls, the body whorl usually only showing the mere
