Turbonillatextilis(?) Kurtz. Plate VIII, fig. 2. 



Chemnitzia textilis Kurtz, Cat. Mar. Shells, p. 8, 1860. 



Turbonilla textilis Tryon, Amer. Mar. Conch., p. 65, 1873 ; IManual, viii^ 

 p. 329, pi. 75, fig. 12 (variety), 1885. 



Shell small, rather stout, bluntly tapered, white, semitranspar- 

 ent, of dull lustre, with swollen whorls bevelled above, just below 

 the suture, forming a rounded shoulder and having a few, coarse, 

 spiral grooves on the interspaces and a few, raised, spiral threads on 

 the base. Suture linear. Whorls 6 below the good-sized, oblique, 

 flattened nucleus. Transverse ribs, which extend a little below the 

 periphery of the body- whorl, are 26, narrow, rounded, prominent,, 

 perpendicular, but a very little inclined to the right on the last 

 whorl, their sides rendered uneven by the cutting in of the spiral 

 grooves, separated by wilder, deep spaces, Avhich are crossed by 5 

 Avide, deep, spiral, grooves of about equal size and evenly separated, 

 the top one just at the shoulder of the whorls. Base elongated^ 

 rounded, cut by two equally Avide, well separated, deep, spiral 

 grooves, interrupted by the ribs Avhich here disappear; below, 

 there are four or five, raised, spiral threads separated by shallow 

 grooves. Aperture very smooth and lustrous within, elongate- 

 ovate with the pillar-lip thin and reflected, especially below. 



Length, 3i mm, ; diameter, 1 \ mm. ; length of aperture, 1 

 mm. 



Two live specimens (jSTo. 72,051) found in two fathoms at 

 Marco, Fla., by Mr. H. Hemphill. A badly Avorn young speci- 

 men from Station 2,114, off Cape Hatteras, N. C, iu fourteen 

 fathoms, dredged by the U. S. F. C. in 1883, agrees closely Avith 

 these, but is too poor to identify Avith certainty. The same is true 

 of an example from Bermuda. 



They are easily recognized by the distinctly shouldered Avhorls 

 and coarse spiral grooves, and may be examples of the true textilis 

 of Kurtz, " AVhorls shouldered " is the only feature giA'en in the 

 original description Avhich separates that species from many others. 



Two small, live specimens (No. 72,043) in the R. Swift collec- 

 tion were collected by Stimpson on the coast of South Carolina and 

 were labelled as T. textilis Kurtz, and figured by Tryon. Both 

 have the apex somewhat eroded and the body- whorl has been in- 

 jured and repaired. They are more slender than the typical form 

 (No, 72,051). The larger has 6 moderately swollen, not distinctly 

 shouldered whorls, below the rather prominent, oblique, flattened
