 not at all nunicrou.s in any of the tertiary deposits, and very few oidy occurrwl 

 at Siirugadai.

Tiureted, with the projiortion of axis to diameter nearly as 3 to 1, with 

 many plain whorls covered by .some .spiral ribs and by curved longitudinal ribs 

 whitli make the former appear granulated, with a broad outer ii|) anil a deep 

 and brii.'.d notch in it, the sjxjcies is cxsily to be recognized. From Lampania 

 multiformis Lischke, the only other sixjcics which is important for this pa|)er, 

 L. zonalis ditfers first hy the djjpjr not^h of the lip, then by the straighter 

 and wider canal. The other differences — stronger sculpture and tendency to 

 graduated whorls in L. zonalis— are not constant. — I leave it undecided whetlier 

 tho.sc two charactci^s suffice to cluirat^terize L. multiformis as a K|x.'cies. From 

 Takigashim-mura (v. ne.\t cliapter), where the Lampani.'u are very frecpient, I 

 have among many specimens provided with a deep notch, some without it, and 

 yet a few of the latter have comi«ratively strong ribs and n gnvluatcd spire. 

 Lischke (v. 2, p. 09, jtl. 5, f. 23 and 24) pronounced them a variety. Other 8|>e- 

 cimcns show an intermediate size of the notch; and even the canal which is 

 companvtively the l)est character, shows, in one or two instances, an intermetliute 

 sliape. At any rate, the specimens of Surugadui, by far less nmnerous than 

 those of Takigashira, all have the charactti-s of L. zonalis Desh. They reach 

 the same size which is mostly seen at Takigashira, viz 34 nun. in height an<l 

 12 in diameter.

 tion, left also unsettled by List^hkc, whether üoulds B|iecics is really a good one. 

 The number of specimens from Yokohama and Takigashira is nmch larger, and 

 moreover some of them show ditferent characters, viz. those of (llobulus inonili- 

 fcr Lamarck: but even there I do not find anv intermediate form. I therefore
