136 SIPHONALIA. 



S. SIGNUM, Reeve. PI. 55, fig. 370. 



Yellowish, marbled with gray or light brown, with five or six 



narrow brown revolving bands. Length, 2 inches. 



S. Japan. 



Yery like S. Cassidariaeformis in shape, but smooth, and more 

 produced and contorted inferiorly. 



S. concinna, A. Adams, may be synonymous, as suggested by 

 Kobelt. 



S. FUSOIDES, Reeve. PL 55, figs. 371, 372. 



Light brown, ridges profusely stained with small spots of 



deeper color, Length, 46 mill. 



Japan. 



Yery like S. Cassidarifzformis, but with longer spire, and 

 somewhat narrower ; the canal also, is a little more produced. 



S. FUSCOLINEATA, Pease. PI. 87, fig. 618. 



Whitish fawn, sparingly streaked longitudinally with brown, 

 and ornamented with sub-equidistant revolving dark brown lines. 



Length, 1-6 inches. 



Corea, 70 fathoms. 



I have not seen this species ; the figure of it appears very 

 closely related to the preceding, and it is probably synonymous 

 with it. 



S. TROCHULUS, Reeve. PL 55, fig. 373. 



Yellowish bay-color, encircled by white raised lines ; light 



chocolate within the aperture. Length, 40 mill. 



Japan.

Whitish, strigated and maculated sparsely with orange-brown. 

 Length, 41 mill. 



Sooloo Sea ; Japan, 35 fathoms. 



The very short canal and smooth surface as well as the peculiar 

 color-markings almost suggest Eburna rather than SipJwnalia. 



S. NODOSA, Martyn. PL 56, figs. 376, 377 ; PL 58, fig. 398. 

 Yellowish white, more or less stained with rust-red. 

 Length, 2-2'5 inches.

 this species.
