TURBONILLA (STRIOTURBONILLA) PEILEI, new species. 



Plate 35, figs. 9 and 9«. 



Shell elongate-conic, light waxen yellow. Nuclear whorls small, 

 forming a depressed helicoid spire, whose axis is at right angles to that 

 of the succeeding turns, and in the first of which they are about one- 

 third immersed. Nuclear whorls two and one-half. Post-nuclear 

 whorls feebly shouldered at the summit, marked by somewhat flex- 

 uous, well-developed, regular, axial ribs, of which 14 occur upon the 

 first and second, 16 upon the third, 20 upon the fourth, 22 upon the 

 fifth, 24 upon the sixth to eighth, 26 upon the ninth, 28 upon the 

 tenth and the penultimate turn. Intercostal spaces about twice as 

 wide as the ribs, well impressed, the depressed portion terminating in 

 a deep pit at the periphery. A second series of pits occurs at the 

 anterior termination of the posterior two-fifths of the space between 

 the sutures. In addition to these two series of pits, the intercostal 

 spaces are marked by fine, very regular, and regularly spaced, incised 

 spiral lines, which are about half as wide as the flattened spaces 

 between them. Of these lines, twenty occur between the two series 

 of pits, while the space between the median series of pits and the 

 summit is marked by fourteen. Periphery of the last whorl slightly 

 angulated. Base moderately long, well rounded, crossed by the 

 feeble continuations of the axial ribs which disappear before reaching 

 the middle of the base, and about twenty irregular and irregularly 

 spaced, sinuous, incised, spiral lines. Aperture somewhat effuse ante- 

 riorly posterior angle obtuse; outer lip thin, showing external sculp- 

 ture within; columella oblique, slightly revolute. 



Two specimens of this species were sent by Mr. Haycock from Ber- 

 muda. These may be considered cotypes. One of these (Cat. No. 

 221610, U.S.N.M.) has twelve post-nuclear whorls and measures: 

 Length 6 mm., diameter 1.3 mm. The other is in the Bermuda 

 Museum. 



The species is named, at the request of Mr. Haycock, for Major 

 Peile, Royal Artillery, of Bermuda, in recognition of kindly assistance 

 rendered by him. 



TURBONILLA (STRIOTURBONILLA) HAYCOCKI, new species. 



Plate 35, figs. 6 and 6a. 



Shell elongate-conic, white. Nuclear whorls two, forming a 

 depressed, helicoid spire, the axis of which is at right angles to that 

 of the succeeding turns, scarcely at all immersed, with the tilted 

 edge projecting slightly beyond the post-nuclear spire on the left 

 side. Post-nuclear whorls almost flattened, slightly shouldered at 

 the summit, marked with strong, well rounded, slightly protractive, 

 axial ribs, of which 12 occur upon the first, 14 upon the second, 16
