66 FAUNA OF BALUCHISTAN. 



Bemarks,— Casts of all sizes which answer to the above description are pretty 

 common at both localities, but all of them more or less damaged. For this 

 reason I have decided not to give them a specific name, particularly as the orna- 

 mentation of the surface is unknown. 



The general shape of the shell agrees very well with the species described by 

 Stoliczka as Melo piriformis, Forbes. It differs, however, by being less broad at 

 the posterior end of the last whorl, but broader at its anterior end. As the 

 substance of the shell is not preserved, it is impossible to say whether there existed 

 columellar folds or not in the Baluchistcin species. Whether Stoliczka's view of the 

 generic position of Melo pyriformis, Forbes, is correct or not, I am not prepared to 

 say ; all I wish to point out is, that some casts from the upper cretaceous system 

 of Baluchistan bear a strong resemblance to it.

The fusiform shell measures about 35 mm. in height, but the apex and part of 

 the spire being broken off, it was certainly much longer. The spire was pretty 

 high and consisted of low whorls, which are slightly concave at the upper part. 

 The last whorl is very high and anteriorly strongly aceuminate. Aperture very 

 narrow and high, outer lip sharp. So far as can be made out, the ornamentation 

 consisted, besides numerous fine striae of growth, of short, rounded nodules, slightly 

 elongated in a longitudinal direction, which were set on a keel which marked the 

 upper concave part of the whorls.

Memarks. — ^This species is easily distinguishable from the others by the 

 elongated, slender shape of the shell. 



Voluta gasparini, d'Orbigny, seems a related form, but it is easily distinguished 

 by the much longer ribs.

Two rather ill preserved specimens may be identified with the above species 

 of Stoliczka's originals. The general shape of the shell was apparently turreted, the 

 spire rather low, and the last whorl about half the height of the shell. The orna- 

 mentation consists of numerous long and rather thick, rounded, longitudinal 

 ribs, which are separated by slightly concave interstices.
