our well-known Nannygai belongs; (8.) the SciceJiidce, another 

 valuable family to which the Jew-fish (Scicena), and the Teraglin 

 {Ofolithus), both large' and excellent fishes, belong; (9.) the 

 TrichiuridcE, among which may be mentioned the famous Frost- 

 fish of New Zealand {Lepidopus\ the Hair-tails {Trichiurus), and 

 the Barracouta of Tasmania {Thyrsites), all of fine quality; (10.) 

 the Caraurjidcc or Horse Mackerels with the Yellowtail and 

 Trevally ( Caranx\ the King-fish and Samson-fish {Sertold), the 

 Pilot-fish {Nancrates) and the Tailor (Temnodon) as representatives. 

 (11) Scofnbrida; or the Mackerels, which includes besides the 

 typical species, a Tunny (Orcynus), and species of Cylium and 

 Elacate^ the latter being found in all tropical seas, and the 

 Sucking-fishes {Echeyieis) with their first dorsal fin transformed 

 into a lamellated sucking disk on the top of the head; (12) 

 Trachinidcr, the best known of which to our readers will be the 

 Whitings {Sillayo) a very delicate morsel ; (13) the Cottidce, con-

 and Lepidotrigla) both of good flavour and the latter with

 no commercial value, but interesting on account of several of the 

 genera bringing forth living young, such as Zoarces, Cristiceps^ kc.

 from whose members may be selected as representatives, the Sea 

 Mullet {Mugil dohula), the Flat-tail Mullet {M. peronii), and the 

 Tallygalane {Myxus elongatus) of whose excellence no mention 

 is necessary ; thirty-six other families belong to this order. 



Order PHARYNGOGNATHI diff"ers from the preceding 

 only in having the lower pharyngeal bones coalesced. Four

 Parrot-fishes, of which we have many genera and species, among 

 which may be mentioned the Pig-fish and Blue Groper (Cossy-
