Euthria hokkaidonis n. sp. PI. XIX, fig. 17. 



Shell slender, fusiform, moderately solid, yellowish or purplish 

 ashen. Surface lustreless, sculptured with slightly oblique longi- 

 tudinal rounded folds as wide as their intervals, 13 or 14 in num- 

 ber on the penultimate whorl, wanting on the base of the last 

 whorl, where they disappear just below the periphery; crossed by 

 spiral cords alternating with threads or striae, of which there are 

 usually two in each interval ; the coarser cords about 5 in number 

 on the whorls of the spire, slightly widening as they cross the longi- 

 tudinal folds; the spirals alone developed on the base. Spire high; 

 whorls about 9, very convex, separated by deep sutures; the last 

 whorl concave below, produced in a slender, somewhat recurved 

 rostrum; siphonal ridge convex. Aperture small, ovate, acumi- 

 nate above, livid dull purple inside, with 8 to 10 acute folds within 

 the thin -edged outer lip; canal short and open. 



Length 22, diarn. 8.5, length of aperture 10 mm. 



Length 22, diam. 8, length of aperture 9 mm. 



Nakauta, prov. Teshio, Hokkaido (Mr. Y. Hirase). Types 

 No. 80,394, from No. 102 of Mr. Hirase' s collection. 



Apparently related to E. fuscolabiata E. A. Smith, from which 

 it differs conspicuously in the much more slender figure. 



COLUMBELLID^J. 

 Columbella misera Sowerby. PI. XXI, figs. 37, 38. 



C. miser Sowb., Thes. Conch., I, p. 129 bis, PI. 38, fig. 111. 

 This species is figured to illustrate its difference from the follow- 

 ing. It was taken in some numbers at Kamakura, province Sag- 

 ami (below the mouth of Tokyo Bay), by Mr. Frederick Stearns. 

 It is very strongly ribbed, especially on the spire, the ribs being 

 about half the width of the interstices, about 11 or 12 in number 

 on the penultimate whorl, or on the last, when they are not obsolete 

 on its latter part, which is frequently the case. On the front of 

 the last whorl these ribs extend well over the periphery, but they 

 become much shorter on its latter half, or wholly obsolete. The 

 base is sculptured with coarse spiral cords, which become increas- 

 ingly weaker and obsolete as they approach the periphery. Color 

 ivhite, ivith one or two dark brown spots on each rib and a checkered 

 striped basal zone; the back of the last whorl irregularly striped or 

 reticulate; a white zone, usually brown-dotted on each rib, re-
