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
1. There is no population in which only rostrate or melanistic shells occur, and normal shells are absent.
2. There is locally a gradual passing from normal shells to sub-rostrate and rostrate ones; Cernohorsky estimated (by letter)
the relative frequency of these stages in Mauritia eglantina Duclos in Mondoure Bay as about 30: 5: 1.
3. Rostration and melanism often occur in the same specimen, but they are not always linked.
4. Localities from which such shells are known, may be scattered over the whole region inhabited by the species, but they
evidently are concentrated in certain smaller areas.
5. The tendency to become rostrate or melanistic differs, as certain species seem not to be susceptible at all or at least
less susceptible to rostration and melanism than other species.
There seems to be no predominance of any sex in rostrate cowries; the radula evidently does not differ from that of normal
specimens.
Certain specific names are persistently used in literature, despite their invalidation by the I.C.Z.N. some 10 years ago. As
I was one of the culprits in using two invalid names in my Catalogue of Living Cypraeidae, I thought it advisable to make the
necessary corrections.
By opinion 261 (published 10th August, 1954), the work of L. T. Gronovius, Zoophylacium Gronovianum, 3 parts, 1763 - 1781,
and F. C. Meuschen's Index to Gronovius' work from 1781, have been rejected as non-binominal. This will invalidate the
