Turbonilla muricatoides The small, slender shell is subdiaphanous to milk white. Its length measures 3 mm. The 2½ whorls of the protoconch are helicoid but slightly elevated and well rounded. Their axis is at right angles to the axis of the teleoconch. The seven whorls of the teleoconch are smooth, rather high between the sutures, and moderately rounded. They are marked by strong sublamellar axial ribs, wliich are about half as wide as the spaces that separate them, and extend strongly to the very summit of the whorl where they render the well-marked sutures crenulate. There are 14 of these ribs upon the first, 18 upon
Turbonilla calvini The milk-white shell has an elongate-conic shape. The length of the shell measures 3.6 mm. The 2¾ whorls of the protoconch form a decidedly elevated helicoid spire, the axis of which is at right angles to that of the succeeding turns, in the first of which they are about one-fourth immersed. A complete shell would probably have twelve whorls in the teleoconch. The early whorls of the teleoconch are strongly rounded, decidedly shouldered at the summit, and constricted at the sutures. Later ones are flattened in the middle, less shouldered and less contracted. The axial ribs are strong, sublamellar, and shouldered a little below the summit. There are 14 upon the first to ninth, 16 upon the tenth, and 18 upon the penultimate turn. The intercostal spaces are about two and one-half times as wide as the ribs. They are well impressed, a little more so on the shoulder than on the summit, which gives them contracted appearance at this place, terminating a little above the suture. The sutures are well impressed. The entire surface of the base of the shell and the spire is marked by fine, wavy, spiral striations. The periphery and the moderately long base of the body whorl are well rounded. The aperture is rhomboidal. The outer lip is thin, showing the external sculpture within. The columella is moderately strong, and slightly curved.
Turbonilla hypolispa whorls of the teleoconch are well rounded, and slightly shouldered at the summit. They are marked by very strong, sublamellar, protractive axial ribs, of which 14 occur upon the second and third, 16 upon the fourth to eighth, 18 upon the ninth and tenth, 20 upon the eleventh, 24 upon the twelfth, and 25 upon the penultimate turn. On the early whorls these ribs are very strong in the middle, bending suddenly toward the summit, which gives them a decidedly angulated appearance a little below their termination. On the last three whorls they are more closely crowded and less strongly developed.The intercostal spaces are about one and one-half times as wide as the ribs on the early whorls. On the last three they are about equal to them, well impressed, and terminating a little above the sutures. The sutures are well marked. The periphery of the body whorl is slightly angulated. The base of the shell is short, and well rounded. The aperture is rhomboidal. The columella is slender, somewhat curved, and slightly reflected.
Odostomia amianta The yellowish-white shell is broadly conic. Its length measures 4.4 mm. The protoconch is small with two whorls which increase extremely rapidly in size and are obliquely placed. The six whorls of the teleoconch are very strongly shouldered, marked by three very strong lamellar spiral keels on the first and second and four on the succeeding whorls between the sutures. The posterior keel marks the limit of the broad, sloping shoulder and is much the strongest. It is also placed a little farther apart from the next spiral keel than that is from its anterior neighbor. The base of the body whorl is well rounded. The shell is ornamented by eight spiral ridges, which are less elevated and much more closely and regularly spaced than those between the sutures. The peripheral groove is about equal in width to the one anterior to the posterior keel. The entire shell is marked by fine, sublamellar, regularly spaced, retractive axial ribs, which render the spiral keels somewhat crenulated at their meeting points and break the spaces between them into small squares or oblongs. These riblets extend from the sutures to the small umbilicus. The aperture is subovate. The posterior angle is obtuse. The outer lip is thin, somewhat wavy, showing the external sculpture within. The columella is moderately stout, somewhat curved and strongly revolute, having an oblique fold near its insertion which is barely visible when the aperture is viewed squared. The parietal wall is covered by a fairly thick callus.
Trabecula laxa The milk-white, smooth shell has a pupiform shape. The length of the shell varies between 3 mm and 4.3 mm.There are at least two small whorls in the protoconch. They form a depressed helicoid spire, whose axis is at right angles to that of the succeeding turns, in the first of which it is about two-thirds immersed. The six whorls of the teleoconch are inflated and sculptured similarly throughout. They are contracted at the sutures, and strongly roundedly shouldered at the summit. A spiral sculpture is wanting. They are marked by sublamellar, flexuose axial ribs, which are only feebly expressed on the first. On the second there are 18, on the third 20, 22 upon the fourth, and 28 upon the penultimate turn, upon which there is a strong varix. The intercostal spaces are about one and one-half times as wide as the ribs, and well impressed. The sutures are constricted. The periphery and the base of the body whorl well rounded. They are marked by the continuations of the axial ribs. The aperture is broadly oval. The posterior angle is obtuse. The outer lip is thin, showing the external sculpture within. The columella is slender, strongly curved, and slightly revolute. It is provided with a weak fold at its insertion.
