Loven, Index Molluscorum Scandinaviae, 12. G. O. Sars, Mollusca regionis arcticac 
Norvegiae; PI. 23, fig. 10. 
Testa fusiformis, graciliuscula, rufa, cancellata costis circ. 13, apertura 
dimidiam longitudinem aequante. Priore gracilior; anfr. 6-7 convexi, 
tumiduli, postice angulati, planulati, cingulis obducti, pone angulum 
tenuissimis, in medio anfr. majoribus, interpostis hie et illic tenuiorbis; 
costae validae, elevatae, postice subsigmoideae, in angulo subnodosae, in 
cauda evantae; autura profunda; apertura angusta, margine columellari 
postice vix sinuato, canali lato, subcompresso; labrum album acutum, 
postice ad angulum sinuatum; fauces obscure fuscae; 10.4; 5.2 mm. 
Differt a “T. harpulario” forma graciliore, anfr. magis tumidis, sutura 
profundiore, costis multo validioribus. (M. Sars.) 
Shell fusiform very slender, reddish, cancellate with about 13 costae, 
aperture equal to half the length, more slender than the former (species) ; 
whorls 6-7 convex, slightly tumid, in the rear angulate, flattened, pro¬ 
longed in zones, very slender behind the angle, stronger in the middle of 
the whorl, with more slender lines intercalated here and there; costae 
strong, elevated, subsigmoidal behind, subnodose on the angle, disappear¬ 
ing on the tail; suture deep; aperture narrow, columellar margin in 
the rear scarcely sinuate; basal canal, subcompressed. Outer lip white, 
acute, in the rear sinuate to the angle; throat obscurely dusky. Differs 
from T. harpularia in the more slender form, in the more tumid whorls, 
deeper suture, and much stronger costae. (Translation.)
