80 THE NAUTILUS. 



The parietal lamella is remarkably strong and extends inward 

 for nearly a whorl. 



In an immature specimen with 5^ whorls the parietal lamella 

 is 0.27 mm. in height. The lower columellar lamella is 0.2 y 

 the upper 0.14 mm. in height. 



NOTES ON RANELLA LAMPAS OF AUTHOES. 



BY E. G. VANATTA. 



Having gone over the specimens in the collection of the Acad- 

 emy of Natural Sciences, using Mr. E. A. Smith's enlightening 

 article (Journal of Conch., vol. 14, p. 226, 1914), I would like to 

 supplement it by recording my impressions. It seems to me 

 that there are three species involved. 



I. BURSA BUBO (L. ). The first name for any of the shells 

 in question is Murex rana [var.~\ bubo Linnseus, 1758. Also in 

 Gmelin. T. bufo Bolten is a synonym. Var. gigantea Smith is 

 a name applied to the extra large size, and var. lissostoma Smith 

 for these with a darker-colored aperture. 



II. BURSA RUBETA (L. ). The second species was named by Lin- 

 nffius Murex rana \yar.~\ rubeta. Also of Gmelin; T. rub eta Bolt., 

 B. rubeta Smith. T. tuberosum Bolt, is a synonym, and has 

 page-priority over rubeta if the names were to date from Bolten. 



III. BURSA TENUIGRANOSA Smith. (B. rubeta var. tenuigranosa 

 Sm. ). The Academy has a fine specimen 10 inches long, from 

 "India," the gift of M. Thomas. It seems to me to be a dis- 

 tinct species. 



A REMARKABLY RICH POCKET OF FOSSIL DRIFT FROM THE 



PLEISTOCENE 



BY T. S. OLDROYD. 



In digging away the dirt from a side hill on my place in the 

 Los Cerritos two miles back from the ocean at Long Beach and 

 over 100 feet above sea level, I found some drift in a fissure or 

 pocket in a hard calcareous formation under seven feet of top 

 soil. It consisted mostly of fine sand and broken shell? and 

 would measure up about one cubic foot. I call it drift from
