210 TORNATELLIDES OF HAWAIIAN ISLANDS. 



furnished, near its base, with a very oblique, low, deeply- 

 seated fold; the upper eolumellar fold appears to be entirely 

 absent. The parietal lamella is about 0.15 mm. in height. The 

 embryonic whorls are encircled by very minute low spiral 

 stride (fig. 2). 



Mr. Sykes based this species upon Gould's figure, but he 

 also gave "Makaweli, Kauai", as the locality of specimens 

 taken by Mr. Perkins. As no comparison of these Kauaian 

 shells with topotypes from Hilo was made, and no description 

 or figure of them was given, we may be permitted to hold that 

 extension of its range as provisional until direct comparison 

 can be made. At present T. confusa is known from Hawaii 

 only.

Shell perforate, narrowly ovate-conic, light corneous, glossy, 

 under a strong lens minutely irregularly striate, thin, trans- 

 lucent. Spire elongate, conic, with slightly convex outlines, 

 the apex obtuse. Suture impressed, simple. Whorls 5%, uni- 

 formly convex, the embryonic increasing rapidly, the rest in- 

 creasing slowly and regularly; the last whorl subcylindrical, 

 rounded and tapering below, convex at the margin of the 

 umbilicus. Aperture long-ovate, with a regularly curved outer 

 margin. Parietal lamella low, erect, slightly sinuous along 

 its upper edge. Columella tumid above, slightly convex below, 

 unarmed. Peristome thin, erect, regularly arched. Umbilicus 

 rather small, almost circular. 



Length 2.5, ddam. 1.4, axis of apert. 1.0, par. lam. 0.07, 

 umb. 0.32 mm. 



Length 2.7, diam. 1.5 mm.

An immature specimen, with nearly 4% whorls (fig. 10), 

 has smooth apical whorls. The parietal lamella is rather 

 strong, erect, about 0.12 mm. in height. The columella is 

 narrowly triangular, with its inner margin almost straight and 

 is furnished with a single low, almost transverse fold.
