SMITH : NOTES ON AUSTRALIAN SPECIES OF SHELLS. 237 



The second Australian species of Segmentina, which I 

 described as S. vicforuE, is also characterised by the total 

 absence of these internal processes, but, as shewn in the figure, 

 it is somewhat different in having more tightly coiled whorls 

 (vide 1. c, fig. 12), but to determine whether this is an individual 

 rather than a specific character requires further material, for at 

 present the species is known only by the unique specimen in 

 the British Museum. 



Melania supralirata. 



Testa elongata, turrita, decollata, nigra, vel saturate olivacea ; 

 anfractus persistentes 5- — 6, superne constridi, inferne convexi, 

 pro/iiinentes, infra suticram sulcis duabus conspicuis spiralibus 

 sciilpti, undique niinutissime transversim striati, lineisque 

 increinenti tenuihiis decussati, ulti/nns parvus, ad basivi si/lcis 

 paucis scidptiis ; apertura rotunde ovata, superne acuminata, 

 antice acuniinate effusa, intus sordide ccerulea ; labruni tenue, 

 superne late sinuatum ; columella arcuata, ccRruleo-albida. 



Longit. afifract. sex 24 mill., diatn. 9 ; apertura 7 longa, 5 lata. 



Hab. : Prince of Wales Island, Torres Straits. 



This species is remarkable for the shortness and peculiar 



shape of the whorls. They are slopingly contracted above, 



and bulging below the middle, somewhat as represented by 



Reeve's figure of M. Wallacei (' Conch. Icon.' fig. 66). Besides 



the two grooves at the upper part of the whorls, others are 



sometimes more or less traceable over the rest of the surface. 



The ridge between the two sulci is in some specimens inclined 



to be nodulous. M. Sooloensis is another species which has 



some affinity with the present ; in that, however, which is a 



smoother shell, the bulge or convexity of the volutions is higher 



up. From evidence afforded by some young specimens, the 



number of whorls in an adult shell, if not decollated, would be 



eleven. 



Fusus Pricei.
