Mitochondrial DNA variation in water shrews (Sorex palustris, Sorex bendirii) from western North America: implications for taxonomy and phylogeography
- M. O'Neill, D. Nagorsen, R. Baker
- Biology
- 1 November 2005
Inter- and intra-specific variations in cytochrome b (Cytb) sequence were assessed in 22 specimens of Sorex palustris Richardson, 1828 and 6 specimens of Sorex bendirii (Merriam, 1884) from 20…
A review of the living New Zealand members of Onithochiton Gray, 1847 (Mollusca: Polyplacophora)
- M. O'Neill
- Biology
- 1985
Two taxa belonging to the genus Onithochiton Gray, 1847 are recognised from New Zealand: O. neglectus neglectus de Rochebrune, 1881 and O. neglectedus subantarcticus Suter, 1906, on the basis of minor, but geographically stable, differences.
Morphological changes in Onithochiton neglectus Rochebrune, 1881 (Mollusca: Chitonidae), and their taxonomic significance
- M. O'Neill
- Biology
- 1984
Children of Onithochiton neglectus have tricuspid second lateral teeth, an anterior mucro, an abbreviated gill-line, scale-like elements on the dorsal surface of the girdle, and a tegmentum which either lacks or possesses only a few, relatively large, ocelli.
MOLECULAR EVIDENCE FOR GENETIC SUBDIVISIONS IN THE DESERT SHREW, NOTIOSOREX CRAWFORDI

Abstract Examination of cytochrome-b DNA sequences from specimens of Notiosorex crawfordi, the desert shrew, indicate that within this taxon there are at least 3 major subdivisions reflecting levels…
Chiton aorangi n. sp., a brooding chiton (Mollusca: Polyplacophora) from northern New Zealand
- R. Creese, M. O'Neill
- Geology
- 1987
Based on an examination of the relevant types, Chiton aorangi is differentiated from its nearest relative,Chiton themeropis Iredale, 1914, and from two other New Zealand species, chiton torri Suter, 1907 and Chiton pelliserpentis Quoy & Gaimard, 1835.
IDENTIFYING VOUCHER SPECIMENS INVOLVING RISK: SHREWS FROM CHORNOBYL, UKRAINE

- 28 February 2003
DNA sequences from the cytochrome-b gene were analyzed to minimize radiation exposure and to evaluate an inexpensive molecular tool in identifying species of shrew, and substantially reduced exposure to radioactivity present in the archived material.
Lepidozona beui n. sp. (Mollusca: Polyplacophora) from New Zealand
- M. O'Neill
- Biology, Geology
- 1987
In the absence of geographically close members of the genus Lepidozona, L. beui is specifically differentiated from the northern pacific species L. mertensii (von Middendorff, 1847), type species for the genus.

- M. O'Neill
- Geology
- 1989
The New Zealand Recent species of Rhyssoplax Thiele 1893 recognised here are R. canaliculata, R. aerea, and R. stangeri, which are reillustrated and compared with the New Zealand species.
