AKT. 18 SMALT^ SHELLS DREDGED BY "ALBATROSS ^^ DALL 75 



narrowly shouldered at the siinnnit, marked by incremental lines and 

 exceedingly fine spiral striations only. Suture slightly constricted. 

 Periphery of the last whorl well rounded. Aperture elongate-ovate; 

 posterior angle acute ; outer lip thin ; inner lip almost vertical, provided 

 with an obsolete fold a little anterior to the insertion of the columella. 



The type, Cat. No. 108051, U.S.N.M., comes from United States 

 Bureau of Fisheries Station 2668, in 294 fathoms, sandy bottom, 46.3° 

 bottom temperature, off Fernandina, Fla. It has nine postnuclear 

 whorls and measures: Length, 6 mm.; diameter, 1.4 mm. 



Cat. No. 108065, U.S.N. M., contains 10 additional specimens from 

 the type locality and Cat. No. 108364, U.S.N.M., contains 2 from 

 United States Bureau of Fisheries Station 2415, in 440 fathoms, sandy 

 bottom, 45.6° bottom temperature, off Georgia. 



PYRAMIDELLA fSYKNOLA) FLOKIDANA, m-v. species 



Shell elongate-conic, cream yellow. Nuclear whorls at least one 

 and a half, forming a very depressed helicoid spire which is obliquely 

 almost half immersed in the first of the succeeding turns. The last 

 nuclear whorl projects materially beyond the outline of the postnu- 

 clear spire. Postnuclear whorls slightly rounded, narrowly shouldered 

 at the summit, marked by fine incremental lines and very closely 

 spaced microscopic spiral striations. Suture moderately constricted. 

 Periphery of the last whorl well rounded. Base moderately prolonged, 

 well rounded. Aperture elongate oval; posterior angle obtuse; outer 

 lip thin; inner lip almost straight, reflected over and apj)ressed to 

 the base for about one-third of its length, provided with an obsolete, 

 oblique fold a little anterior to its insertion. 



The type. Cat. No. 108056, U.S.N.M., was dredged at United States 

 Bureau of Fisheries Station 2668, in 294 fathoms, sandy bottom 

 46.3° bottom temperature, off Fernandina, Fla. It is an immature 

 specimen of 5.5 whorls and measures: Length, 3.5 mm.; diameter 

 1.1 mm. 



PYRAMIDELLA (SYRNOLA) GEORGIAN A, new species 



Shell elongate-ovate, bluish white, semitranslucent. Nuclear whorls 

 very small, immersed in the first of the postnuclear turns, above w^hich 

 the rounded edge of the last volution only projects. Postnuclear 

 whorls well rounded, moderate^ shouldered at the summit, marked 

 by lines of growth and fine, closely spaced microscopic spiral striations 

 only. Suture scarcely constricted. Periphery of the last whorl Avell 

 rounded. Base short, strongly rounded, marked like the spire. 

 Aperture oval; posterior angle acute; outer lip fractured, showing 

 four spiral lirations within, of which two are anterior to the periphery 

 and the other two are about an equal distance posterior to it; inner 

 lip stout, reflected and appressed to the base for half its length and 

 provided with a rather strong fold a little anterior to its insertion.
