Description

Indopacific species recorded several times in many localities of the Levant Sea coasts (CIESM Atlas, 2004). Shell small, elongate, with very convex whorls, the two last ones of equal diametre. Protoconch made by two smooth whorls, teleconch with spiral sculpture made by undefined little ridges. It can be seldom confused with other Mediterranean species. This is due to its special spiral outline, to the roundish aperture and to the lack of the siphonal tube. Background colour: dirty white with a spiral set of brown spots (3 ones on the last whorl, 2 ones on the previous whorls). Also the young shells, of course more conical in form, can be easily classified for their colouring pattern and sculpture. There can be found specimens uniform brown in colour. The average measures are 3 mm in height.

Finella pyrrhacme: Among shell sand on the lagoon beach of Funafuti I gathered a dozen specimens specifically in-separable from the Panie shells which I thus identified. They are smaller than Mel vill and Standee's specimens, being barely four milli-metres in length, whereas theirs are six, the tips, unlike my Panie examples, are faintly and barely touched with colour, as if singed by fire. In contour they exhibit much variety ; two examples are drawn to the same scale to illustrate diversity of proportion, perhaps a sexual feature. The apex, which I hold to exhibit characters of generic importance, consists first of two very minute whorls which are almost buried in the succeeding whorl. These are very difficult to observe, being seen in two instances only in the series examined. A globose whorl, longitudinally ribbed, sometimes only obliquely wrinkled, commences the real spire. This, the subsequent whorl and the tip, together form an acicular point to the shell when viewed through a handlens. The second, third, and fourth whorls are tabulate, lending a pagoda aspect to the upper spire. These are the whorls stained chestnut, so dark as to be almost black, in the New Caledonian specimens. The larger whorls are closely corded by spiral lyrfe, having smaller lyrse in their interstices. Weak, longitudinal ribs undulate the central whorls and appear on the last whorl, but vanish there before reaching the periphery. The columella lip is broad and reflected, obliquely ridged within and sharply bent above. The aperture is perpendicular, ovate and grooved within.
Hedley,C., 1899. The Mollusca of Funafuti.
The species is characterized by 1) ovate, moderately high-spired, cyrtoconoid shell attaining 4 mm in height, 2) protoconch of 2-2.5 smooth whorls, with a weak spiral thread over the last half whorl, 3) teleoconch whorls convex, with the periphery placed about midway between sutures, 4) body whorl about one half the total height, 5) aperture oval with simple inner lip, 6) sculpture of thin collabral folds and overriding flat spirals; 8 spirals occur on mature whorls, 9 on the body whorl and 7 over the base. As already noted by PONDER (1994), the species is rather variable in shape, convexity of whorls and sculpture; the axials may be obsolete.

Distribution

Indo-Pacific. They were collected in several localities of Israel, Turkey, Lebanon and Cyprus Mediterranean coasts always in low depth
