whorls are slightly convex and have a weak angulation just below the middle, it is expressed by a spiral cord. On the inner mould, the angulation is reflected near the peristome only, similarly to the lower, weaker angulation. The peristome itself is very poorly preserved, the apical and the columellar digitations are observable on one of the specimens, but the shape of the outer lip between them is uncertain. Spiral threads cover the whole shell, two of them are stronger (cords'

; one on the angulation of the whorls. The other one is visible only on the last whorl below the first one, and it is just overlapped by the suture on the spire. The collabral ornament consists of fine, opisthocyrt growth-lines and, on the juvenile part, riblets with small spines at the angulation. The number of the spines are smaller than that of the riblets. The spines follow each other with more or less regular interspaces. About 120° before the peristome, a spine of an earlier peristome is visible. Remarks : The habit of this form corresponds to the subgenus Trietteia Conti and Szabó, 1987. That is why we use the subgeneric name without sure knowledge about whether this species has a third digitation on the outer lip or not. A decision in this question needs further material. Though DE GREGORIO's description and figures do not fit well on VACEK's specimens, we have to accept his specific name and him as author, because in the appendix to his paper he states the identity of his Alaria mipa and VACEK's Alaria n. sp. indet. DE GREGORIO's material has been lost, so a comparison is impossible. The most closely related species is Piettei

a (Tri

etteia) trispinigera Szabó, 1983 but it has a lower number of whorls and so a bigger suturai angle. In P. (T. ? ) mipa, the ratio of the nearly cylindrical shell part is bigger in comparison to the total height.

: an inner mould with shelly portions (1886/5/65) Measurements

: H HL HA D W A 22 17 7 16 10 65° Description : Only a medium sized, littoriniform specimen is available. Its rather low spire is composed of convex whorls with sharp angulation at the upper third of the distance between the two sutures. This angulation délimites a moderately broad, concave ramp. The hardly convex outer face curves on the last whorl into the convex, anomphalous base gradually. The inner space of the whorls is ovate, the peristome is unknown. Except the ramp, the shell is covered by dense spiral laces with intersecting narrow grooves. Strong, regularly repeating varices give the transverse ornament. They do not reach the suture, and end just below the periphery abaxially. The growth-lines are a bit prosocline below the ramp angle, and opisthocyrt-prosocline on the ramp. Remarks : Purpurina elaborata (Lycett) is the species, which bears a similarly dense spiral lineation, but VACEK's specimen has a somewhat higher spire and a bigger suturai angle. In these latter two characters this specimen resembles to HUDLESTON's (1887) Purpurina "var, or species" in pl. I, fig. 2, but its lineation is sparser and much more marked. Purpurina bellona d'Orbigny has a quite sparse lineation.
