longitude 66°i>'45" W. and latitude i8°32' N., longitude 66°2i' 

 15" W. 



This species comes nearest to Leucosyrinx vcrrilli, from which it 

 differs markedly by its more slender form and more numerous no- 

 dulose ribs. 



FUSITURRICULA ENAE, n. sp. 

 Plate 3, figs. I, 2, 10 



Shell of medium size, fusiform, pale horn-colored, with the inter- 

 costal spaces pale chestnut-brown, and with a pale chestnut-brown 

 median basal band, and the tip of the columella of the same color 

 Nuclear whorls 1.5, smooth, well rounded. A few closely spaced 

 wrinkles mark the transition of the nuclear turns to the postnuclear 

 whorls. Postnuclear whorls moderately high. The first bears a strong 

 median nodulose cord. On the second this cord tends to split and 

 from there on develops into two nodulose cords, the nodules repre- 

 senting the axial ribs. The nodules on the first postnuclear whorl are 

 cusplike, whereas those of the succeeding turns become increasingly 

 more rounded and elongated, their long axes corresponding with the 

 spiral sculpture. Of these nodules, 10 occur upon the first and second 

 turn, 12 upon the third and fourth, 14 upon the fifth and sixth, and 

 16 upon the seventh and last turns. Anterior to the two nodulose 

 spiral cords the whorls are marked by four almost equal and equally 

 spaced spiral cords. Periphery and base well rounded. The latter is 

 marked by five equal and equally spaced spiral threads. The entire 

 base and the anterior portion of the whorls are in addition crossed 

 by rather coarse lines of growth, which are particularly emphasized 

 between the spiral cords. Columella long and attenuate, marked by 

 19 rather distantly spaced, somewhat flattened, low, spiral cords. 

 Aperture very elongate, decidedly channeled anteriorly and with a 

 very deeply cut sinus immediately below the summit. Outer lip thin. 

 Inner lip slightly excavated, appearing as a white callus.
