AbstractDrupa (Maculotriton) buitendijki n. sp. (Pl. I, fig. 1).
Testa parvula, tenuis, elongato-turrita, nitidula. Anfractus 10, apice laevi anfractibus 3l/2 annumerata, liris subtilimis, longitudinalibus et transversis ad decussationem nodulosis reticulata Varices 10. Apertura ovata, utrinque attenuata, labro intus elevato-striato, inferne in canalem brevem subrecurvum desinens. Lutescente-albida, fuscescente hie illic tincta, apertura alba.
Long. 14,5 mm, lat. 5,5 mm.
Shell small, thin, elongately turreted, glossy. Whorls 10, including a smooth, rather acuminated 31/2 whorled nucleus. Sculpture: varices 10.
Whorls and also varices with very fine longitudinal and spiral striae, which at their intersection form a little nodule, producing thus a net with quadrate stitches. On the uppermost whorls the longitudinal striae are the most developed, while the spiral striae become more distinct on the last whorl. When weakly magnified the intervals between the spiral lines appear as very fine spiral threads, which are intersected at some places by still finer, almost invisible, longitudinal threads. Aperture ovate, posterior angle acute, outer lip elevately striated within. Columella excavated, polished.
Canal short, a little recurved, about half the length of the aperture.
Coloration: straw white, dotted here and there with light brown; aperture white within.
Length: 14,5 mm, breadth: 5,5 mm.
Locality: Manoekwari (N. Guinea), collected by W. C. van Heurn, 1920. The type specimen in 's Rijks Museum van Natuurlijke Historie, Leiden. Cat. N°. 48a.
