92 "TERRA NOVA" EXPEDITION. 



sloxvlv increasing, sculptured witli slightly curved longitudinal fine eosta: and spiral 

 lira, the points of intersect ion forming small rounded nodules : costs? about twenty- 

 six on the penultimate whorl, lirte six or seven ; body- whorl contracted below the 

 middle, beneath which the shell is scarcely affected by the longitudinal costae, so 

 that the transverse lirge are smooth, and not nodulous ; aperture narrow, suboval ; 

 labruin thin at the edge, a little thickened exteriorly, with about seven slender, 

 short lira} within, a short distance from the margin : columella arcuate above, 

 oblique below, covered with a thin callus. 



Length, 15 mm. ; diameter, 5'5. Aperture, with canal, mm. long, 2 broad. 



Station 38, West of Falkland Islands : 125 fathoms. 



Remarkable for the slender acuminate form. Although the obscure colour 

 markings are somewhat irregular, the light reddish spots are mostly at the upper part 

 of the whorls, and the body-whorl has an obscure band just below the periphery. 



3. T/'oji/Kiii fie/xt'iii'i'rt. n. sp. PI. II, fig.s. 6, 7. 



Shell fusiform, dirty white ; whorls 7 5. The apical two and a half, forming 

 the embryonic shell, convex, smooth, the rest sloping above, then angled and 

 contracted below, having longitudinal lamellae, produced above into hollow backwardly 

 curved spines, spirally lirate rather strongly, and also sculptured with very finely 

 lamelliform lines of growth. The longitudinal lamellae are about eleven in number, 

 smooth on the front side, but sculptured behind with the lines of growth and the 

 spiral lirae ; aperture pyriform, produced into a rather narrow, oblique, anterior 

 canal ; outer lip thickened by the last lamella ; columella arcuate above, covered 

 with a thin, white callus, joining the outer lip above, and extending along the 

 canal in front. 



Length, 20 '5 mm. ; diameter, 9 '5. Aperture, with canal, 11 long, 4 in width. 



Station 38, west of Falkland Islands : 125 fathoms. 



Two specimens. Remarkable for the strong spiral lirae and the longitudinal 

 lamellae, produced upward into hollow r curved spines. The general form of the shell 

 is rather like that of T. carduelis, Watson,* found in 410 fathoms off Sydney. Named 

 after Professor Pelseueer of Ghent.
