constricted, very short, deep, and slightly recurved. Height of shell, 

 13.7; of last whorl, 6.5; diameter, 5 mm. Cat. No. 106495, U.S.N.M.

ELAEOCYMA HALOCYDNE, new species. 



Plate 4, fig. 4. 



Shell slender, acute, rather flat-sided, purplish brown usually more 

 or less obscured by a yellowish white glaze: nucleus with the first turn 

 smooth, inflated, the second has a peripheral keel and is followed by 

 about eight and a half subsequent Avhorls ; suture strongly appressed 

 Avith a smooth narrow band in front of it and behind the somewhat 

 constricted fascicle; other spiral sculpture of sharph' incised lines, 

 four or five on the spire between the sutures, equal and with wider 

 equal rounded interspaces, and about 24 on the last whorl, the inter- 

 spaces becoming more cord-like near the canal and sometimes feebly 

 nodulous where the lines cut the ribs; axial sculpture of (on the 

 penultimate whorl about 18) feeble narrow ribs, stronger near the 

 apex, obsolete on the last whorl, with wider interspaces, beginning in 

 front of the fascicle, hardly reaching the base, and prctractivel}'^ 

 oblique ; there are also fine sharp incremental lines, chiefly evident in 

 the depressions, but here and there finely reticulating the interspaces ; 

 aperture rather wide, anal sulcus conspicuous, rounded ; outer lip thin, 

 prominently arcuate, smooth within; inner lip with a thin layer of 

 brownish enamel, the edge raised anteriorly ; canal distinct, slightly 

 constricted, with a small concentrically striated siphonal fascicle. 

 Height of shell, 18; of last whorl, 10; diameter, 6 mm. Cat. No.

ELAEOCYMA AEOLIA. new species. 



Plate 3, fig. 1. 



Shell small, brilliantly polished, pinkish brown, with a minute 

 smooth-pointed nucleus of three whorls and seven subsequent 

 Avhorls; suture distinct, appressed, constricted, and slightly undulated 

 by the sculpture; spiral sculpture of (on the spire two) incised lines 

 in front of the shoulder with much wider interspaces, on the last 

 wliorl there are about 10, extending to the canal ; axial sculpture of 

 (on the last whorl 11) rounded prctractively oblique ribs, somewhat 

 lighter colored than the body of the shell, extending from the 

 shoulder to the base and not crossed by the incised lines, the inter- 

 spaces subequal, the ribs not continuous up the spire ; aperture rather 

 wide, and sulcus well marked, short and close to the suture; outer 

 lip thickened, the edge sharp; inner lip erased, pillar short, canal 

 wide, short, slightl}^ recurved. Height of shell, 7; of last whorl, 3.5: 

 diameter, 2.5 mm. ' Cat. No. 208592, U.S.N.M.
