Tlie bluffs near tliu station of Kanagawa (tlie liist iVom Yokoliania in tlic 

 direction to Tül<io) give a very good i lea of the strata in i^nestion and of tlie 

 way in which they are unconforniably covered hy the r|naternary beds, and there- 

 fore have been represented not only in the above-quoted figure, but also in 

 figure 2 and 3, plate I; yet they are not rich in fossils. The hi^li, nearly vertical 

 blnffs are almost everywhere compose 1 of t;Tr.ij-\>us, grayish-green rocks, mostly 

 a little soft, and .'icparated into thick strata. They arc, of coinsc, limited above 

 by an undulating line, near which, in the stiuta them --elves, sometimes a few 

 shells appear. This is also the case in some parts of the lower strata, but the 

 number of the s])ecimens is always small, and they are scattered over the slope 

 of the tufacoons and sandy clay. 



Tlie greater part of the ^loUusca found arc large and small specimens of 

 Xuciila Cohholdiae Sow., which, though mostly breaking into small fragments 

 when taken out of the native rook, yet in a few instances were good and always 

 heljied to make out the characters of the interesting species. It was here tliat 

 the specimen (PI. VI, f. 2S") with tlie smooth inferior belt of 2.0 millimeters in 

 breadth was found. Next to be mentioned is M;ja arenaria Linne which will 

 be discussed with other species found at Takigashira-Mura where it is abundant. 

 To finish the list of Conchifera, I have only to add Ot^trca t/i'jas Tlnndi., I'c- 

 cten j)lica L. Area sulcrciiata Lischke, Dosinia eaoJeta L. and Tnjics dccus- 

 sntus L. Gasteropoda are not found e.Kcept two Ni-ptuneae, one of which is 

 -V. gracilis da Co.stix, whilst tlie other turns out to be the true ^V. island iea 

 Chemn. (Conchyl.— Cabinet, v. 4, p. 1.10, pi. I4l. f. \M-2 and 1313; Jeffreys, 

 Ijrit. Conch, v. 4, p 333). It differs Wmn the foregoing, as his been said above 

 (vide chapter ö, Sliinagawa), by a more obtu.se, bulbifonn and iiiiturned ape.x ; 

 besides, it lias a more elongated spire, whilst the transverse stri;c on the whorls 

 do not ditTer from thfise af N. gracilis.
