AbstractSome time ago Prof. Dr. W. Weyrauch at Lima, Peru, sent to me specimens of a species of the subfamily Neniinae that proved to be new to science. Already about 70 species of the subfamily have become known from Peru, for an important part discovered by Prof. Weyrauch himself.
Andinia (Ehrmanniella) flammulata spec. nov. (Figs. 1, 2) Diagnosis. A small, rather fusiform species of the subgenus Ehrmanniella Zilch. The decollated shell is provided with rather irregular fine white striae.
Especially below the suture these striae are thickened, strikingly white, and arranged in groups of about 5 to 15 on low nodules. These nodules alternate with brown, quite smooth, malleated patches. At some distance it looks like small white and brown areas running obliquely over the surface of the shell below the suture. Lunella more or less interrupted below the middle. The principal plica is only 1/4 whorl long. The receptaculum seminis and its duct unto the junction with the diverticulum are as long as the diverticulum itself.
Description. The shell is decollate, somewhat fusiform, moderately strong, with rather convex whorls of which the penultimate is broadest. Whorls of the decollate shell 4 to 7; some shed tops (juvenile shells) with straight outlines consist of about 10 whorls; sculptured with low, but rather large nodules (which can be taken as corresponding with the upper parts of the obliquely running ribs of Polinski's Nenia wagneri1)) below the suture, provided with groups of about 5-15 clear white striae, between these nodules there are brown smooth patches, often running obliquely below the nodules; 1) „breite, niedrige, stumpfe und wulstartige Rippen, welche von links oben nach rechts unten verlaufen". the middle and lower parts of each whorl are usually rather irregularly
