Recently T. A. Garrard (1963, Journ. Mall Soc. Australia 7:45, pl. 7, fig. 5-6) described Neosimnia tinctura n. sp. from
Moreton Bay. The dentate outer lip excludes it from Neosimnia or Pellasimnia (which genus replaces Neosimnia in the
Indo-Pacific) and from the subfamily Volvinae altogether; it really belongs to the other subfamily, Ovulinae, of the family
Ovulidae (which name must replace Amphiperatidae since the author of Amphiperas, (Gronow), has been declared invalid by
opinion 261 of the International Commission of Zoological Nomenclature).
The general characters of tinctura agree with Primovuia striatula Sowerby and its Eastern subspecies renovata Iredale, which
have been figured in my monograph of Amphiperatinae in 1932 (Proc. Malac. Soc. London 20:58, figs. 17 and 16 respectively),
and differ quite from Pellasimnia formicaria Sowerby and P. subreflexa Adams & Reeve with which Gerrard compared his "new
species." Primovula striatula striatula lives in the Arabian Sea, its subspecies renovata spreads from Malaysia through
Queensland to Sydney, and a third subspecies, verconis Cotton & Godfrey, has been found in South Australia and Albany (see
Schilder 1941, Archiv. Mollusk. 73:107).
The renovata from Mackay and Yeppoon as well as those from Port Jackson are purplish pink with a whitish dorsal zone, a paler
pink outer lip, and orange extremities, the tinctura from Moreton Bay, however, are fawn with the base almost fulvous, but
otherwise identical in general features (as dorsal striation and keel, dentition of the outer lip, funiculum, fossula, orange
extremities, etc.) except in size and shape: Chart by Maria Schilder
Shells, like gold, are where you find them. But certain shells live in well defined areas and habitats. Definite techniques
must be developed for working each of the various habitats of the many species of shells found on Oahu. Probably the most
difficult habitat to work are the large coral heads.
Isolated coral heads located in sand flats, or in sloping hard pan areas, are much more apt to produce good shelling than
areas covered with windrows of coral formations. A good shelling area is shown in the photo.
