A REVIEW OP THE VOLUTIDAE 



The shell Is white, smooth, thin, 

 covered with a weak enamel, the spire point 

 ed, whorls rapidly Increasing In size to- 

 ward the last, aperture large. The columel- 

 la with a slightly projecting somewhat 

 curved edge, without cross folds. The ab- 

 sence of these folds Is characteristic of 

 Barpovoluta just as Guivillea of Watson dif- 

 fers in the form of the shell. 



The specimen taken at the "Gauss- 

 berg" was in great part covered by "Aktiniaj 

 through the removal of which, and the fur- 

 ther preparation of the soft parts, the 

 very fragile edge of the aperture was in- 

 jured and possibly the illustration does 

 not accurately portray Its correct shape. 

 The nucleus of the shell is not preserved 

 and therefore the correct number of whorls 

 cannot be determined. Upon the spire, be- 

 neath the enamel, a reading glass brings 

 out the fine spiral striae, body whorl 

 without the striae.

Thiele seemed in doubt concerning 

 this form, jle stated that the edge of the 

 aperture is hardly thickened but fairly 

 strong, which may indicate that the shell 

 is fully developed. Then the typical 

 spire seems to be more pointed and compara- 

 tively higher. The edge of the columella 

 is more strongly twisted and more separated. 

 The edge of the aperture below is less 

 bent. The striae consists of numerous 

 thread-like lines which are especially 

 clear upon the anterior portion of the 

 body whorl. 



Genus FULGORARIA Schumacher I817 



Pulioraria Schumacher: l8l7> Essai. Syst . , 

 p. 2i^2, 1817- 



Genotype: F. fulminata fulminata Sowerby. 



Range: China and Japan. 



The distinguishing characters of 

 this genus are the swollen, bead-like nu- 

 clei; the initial whorls being lateral as 

 in Mamillana . The shells are somewhat 

 elongated and swollen in the center. Col- 

 umella plaits varying from one to seven, 

 moderately oblique.

Alt. 100-125 mm. 



Hab . Japan . 



Nucleus consisting of two whorls, 

 shining, malleated; apex, lateral; post- 

 nuclear whorls four and one-half; suture 

 somewhat puckered; sculpture consisting of 

 light spiral striae, most pronounced near 

 the suture; rounded longitudinal ribs most 

 prominent at the periphery; columella with 

 four weak plaits; ground, yellowish- flesh 

 color, overlaid with a pattern of longitu- 

 dinal tan streaks, which, where omitted, 

 form faint lighter- colored spiral bands; 

 interior slightly lighter. 



Easily recognized by its narrow 

 axial stripes.
