Abstract

CARCHARHINIDAE. Carcharhinus greyi greyi, second recorded specimen from Tasmania
(first recorded as C. brachyurus); head in plan, mouth parabolic curves, orthogonal
polynomials fitted; girth of head an exponential function of length from snout tip;
notes on dentition, coloration; key to Tasmanian carcharhinids.
SPHYRNIDAE. Sphyrna zygaena, second recorded Tasmanian example, female, compared with
first, male; logarithmic lengths to seven morphological landmarks yield a linear graph
when plotted on logarithms of seven natural numbers (similar formulations in other
sharks).
SYNGNATHIDAE. Syngnathus phillipi, study of two samples (meristic and morphometric
data, variation within and between samples, supposed sexual dimorphism, pouch, coloration,
depth range): Syngnathus caretta (apparently known only from type-specimens)
reported from Tasmania; current knowledge of species extended: IchthyocaIlzpus runa
noted as a Tasmanian species: Syngnathus poecilolaemus, metrical data.
LAMPRIDAE. Lampris regius, new and old local records.
SCORPIDAE. Scorpis aequipinnis, morphometry and coloration in a juvenile sample;
comparison with adult material, yielding data on regional relative growth.
LEPTOSCOPIDAE. Crapatalus arenarius, new subspecies described and figured.
TRIPTERYGIIDAE. General review of Tasmanian representatives, with key; Tripterygium
clarkei (later placed in Gillias and Norfolkia) here referred to Helcogramma: specimen
noted in R.M. Johnston's memoranda, identified as T. clarkei by Whitley, now described
as a new species: Gillias macleayana, new material, table of dimensions: two new
species of Forsterygion (New Zealand genus new to Australia) described and figured:
Brachynectes fasciatus retained in that genus; size classes.
ECHENEIDAE. Remora remora, observations on two Tasmanian examples (host, Luth); outline
of disc fitted with second degree polynomial; lengths of transverse ridges of
disc an exponential function of their serial numbers; unusual white markings in one
specimen.
SYNANCEJIDAE. Glyptauchen insidiator mirandus, habits; first detailed account of the
subspecies; length-number patterns of spines and rays; taxonomic status discussed.
