60 PAUNA OF BALUCHISTAN. 



Cerithitjm BUDDHA, spec nov. PI. XV. fig. 4, 5. 



The turreted shell attains a height of 70 mm. ; it consists of more than six 

 moderately high, strongly rounded whorls, which increase very slowly in height. 

 Just helow the suture the whorls are somewhat contracted, which makes them 

 appear still more rounded. The ornamentation consists of strong longitudinal ribs, 

 which rise into short compressed spines. There are about six to seven in each 

 volution ; ribs and interstices are crossed by numerous fine revolving lines. 



Locality and stratigraphical position. — Mazdr Drik, horizon 8. 



Hemarks. — All the specimens are very much damaged, but the abovementioned 

 characters are still recognized; this species is therefore characterized by the 

 latalU ij)m pressed longitudinal ribs, which rise in short blunt spines, being 

 arranged in continuous lines from the apex to the last whorl and separated by broad 

 interstices on which only fine revolving lines can be seen. 



This peculiar ornamentation distinguishes Cerithium buddha from all the other 

 species. I cannot find any other form closely related to it, although there is not 

 the slightest doubt that Cerithium vishnu, Cerithium buddha^ together with 

 C. mosperianum, d'Orb., or 0. matheronii, d'Orb. and many others, form a natural 

 group, which is chiefly characterized by strong knob-like longitudinal ribs, arranged 

 in continuous lines from the apex to the last whorl. 



Cerithitjm (?) sp. PI. XIV. fig. 14)-14a, 15-15a. 



Two moderately large casts of a turreted shell belong perhaps to this genus ; 

 the shell consisted of rounded whorls, which slowly increase in height, separated 

 by a deep suture. The last whorl, which is just a little higher than those following 

 the spire, bears a few strong spiral keels ; otherwise nothing is known about the 

 sculpture. 



Besides the two casts there is a fragment of a shell which, judging from its whole 

 appearance, belongs probably to the same species : to judge from its size it must have 

 formed part of the earlier whorls. The low rounded whorls are separated by a deep 

 suture ; the ornamentation consists of four to five rounded spiral keels, of which the 

 centre one is the strongest. In the interstices there are fine revolving lines, while 

 numerous moderately strong transverse and equidistant ribs cross them, producing 

 fine nodules at the point of crossing. 



Locality and stratigraphical position. — Maz^r Drik, horizon 8 ; Des valley. 



Remarks. — So far as can be judged from the ill preserved specimens, there is 

 no other species which it resembles ; and if better material were at hand, allow- 

 ing a more definite opinion, it is quite possible that this form might prove a new 

 species. 



Cerithium maximum, Binlc, bears a distant resemblance, but it certainly 

 dilTers from the Baluchistan form.
