CERNOHORSKY (Auckland Institute and Museum, Auckland, New Zealand) Text-figs. 1-19) (fimp of a revision The examination of type-specirnens Nassariidae in preparation for of Indo-Pacific Nassariidae, has brought to light new information which has a bearing on the established taxonorny of Nassariidae, in the way of chronelogical priority and alterations in synonymy. In case of Japanese Nassariidae, a DuNKER species is introduced into Japanese literature, while the synonyrny of other species is elucidated.

As far as the colouring is concerned, individuals vary from white, cream to brown, and sometimes are banded either with brown or white, depending which base colour predominates. Although specimens have been recorded as deep as 116 meters, in the Fiji Islands specimens were found in numbers by hand-dredging in shallow water. Specirriens taken in an area of only 10 square meters, matched practically every variant of N. Pamperus ever described, with the exception of the uniformly dark brown form. the types described CARPENTER (1865) who compared Pease's specimens with by GOuLD, considered Nassa microstoma PEAsE, to be a white variety of N, "N. "IV. dermestina GOuLD, and synonymized tztr-ricula PEAsE" (MS narne), name) and with N. GOULD. undesciata PEAsE" (MS N. PlebeculaGoui.D, Patopera who reported the species under the name N. tringa SCHEPMAN (1911), "a SOUVERBIE, from Indonesia, in 32-91 meters, observed that it was variable species.... specimens are nearly plain-coloured or with conspicuous bands or only with brown lines, their size is variable as well as the number of parietal and N. columellar denticles".

Plebecula with N. dermestina, but largely ignored N. PauPera, an earlier name based on an immature specimen. The data on the type-specimens is as follows: Nassa Pazipera GouLD, 1850: The holotype is in the National Museum of Natural History, Washington, No. USNM 5726, dimensions length 9. 1 mm, width 4.8mm. It is a worn, immature, creamy-yellow specimen with 17 axial ribs on each of the last 2 whorls, 4-5 spiral threads on the penultirnate whorl and 11 on the body whorl, the columella has 8 plicae and the outer lip 9 denticles. Nassa microstoma PEAsE, 1860 : The holotype is in the British Museum (Nat. Hist.), London, No. 1961458, dimensions length 9.0mm, width 4.0mm. It is a slender, juvenile individual which is white with a single brown band on each and whorl, 15 axial ribs on each of the last 2 whorls and the columellar plicae denticles on the outer lip have not as yet developed. Nassa dermestina GouLD, 1860: The holotype is in the National Museum of Natural History, Washington, No. USNM 24166, dimensions length 7. 0mm, width 3,4mm. The specimen is slender, creamy-yellow in colour, and has 16 axial ribs on each of the last 2 wherls. Being an adult, the columella is calloused and plicae and denticles are present. Nassa Plebecula GouLD, 1860: The lectotype is in the National Museum of No. 24168, width Natural History,Washington, USNM dimensions length 10.3mm, each of 4,8mm. The specimen is light yellowish-brown and has 17 axial ribs on the last 2 whorls and is fully mature with a calloused, plicate columella and denticulate outer lip. NassaProducta SOwERBy, 1897: The holotype is in the British Museum (Nat, Hist.), London, No 1899.4.14.3604, dimensions length 13.7mm, width 5.7 mm. The specimen isadirty cream in colour, has 16 axial ribs and 7spiral threads on the penultimate whorl and 14 axial ribs and 10 spiral threads on the body whorl. Being adult, the columella is calloused and plicate and the outer lip - denticulate. From examination of numerous Indo-Pacific specimens and comparison with the types, it is concluded that Nassarius (Hima) Pauperus (GouLD, 1850), is the earliest applicable name for the species. It is widely distributed throughout the to East tropical and temperate Indo-Pacific, ranging from East Africa Japan, Australia to Polynesia, IVassarizas (Hima) fuscolineatus (E. A.
