The different kinds are—

Black Trevally— <i>Teuthis nebulosa</i>, Quoy, family <i>Teuthididae</i> (a New South Wales fish).

Mackerel T. (so called in Tasmania)— <i>Neptonemus dobula</i>, Gunth., family <i>Carangidae</i>.

Silver T.— Another Tasmanian name for the White Trevally, <i>Caranx georgianus</i> (see below).

Snotgall T.—
<i>Neptonemus travale</i>, Casteln. (in Victoria);
<i>N. brama</i>, Gunth. in Tasmania); both of the family
of <i>Carangidae</i>.

White T.— <i>Caranx georgianus</i>, Cuv. and Val., family <i>Carangidae</i>; (so called in New South Wales, New Zealand, and Tasmania; in Victoria it is called <i>Silver Bream</i>). <i>Teuthis javus</i>, Linn., family <i>Tuethididae</i>.

The Maori name for the <i>Trevally</i> is <i>Awara</i>, and in Auckland it is sometimes called the <i>Yellow-Tail</i> (q.v.). See also quotation, 1886.

Guenther says, the genus <i>Teuthis</i> is readily recognised by the peculiar structure of the ventral fins, which have an outer and an inner spine and three soft rays between.

1769. `Capt. Cook's Journal' (edition Wharton, 1893), p. 164:

"Several canoes came off to the ship, and two or three of them sold us some fish—cavallys as they are called—which occasioned my giving the Islands the same name."
