424 ON THE MUGILID.E OF AUSTRALIA, 



bluish ; the fins yellow. Two specimens about three and a-half 

 inches long. Nicol Bay, Western Australia. 



Nota. — The position of the teeth would place this fish with 

 Agonostoma, but it is so absolutely similar to some species of Mugil 

 as to make me unwilling to put it in any other genus, the more 

 so as the cleft of the mouth agrees with Mugil, and not with 

 Agonostoma. I doubt very much also if this latter genus will be 

 maintained, as I think other sorts will form passages between 

 the two." 



12. Mugil ckenidens, Kner. 



Voy. Nov. Fische, p. 229, pi. 9, fig. 6. 



D. 4. 1/8. A. 3/9. L. lat. 43—44. L. trans. 12—13. Ap. pyl. 2. 



" Dentes crenati uniseriales intermaxillares, ciliati pluriseriales 

 in ambitu niaxilla) inferioris, vomer, os palatina, pterygoidea et 

 linguale dentibus velutinis obsita." 



I will not give any further detail of this species, as it can 

 scarcely be confounded with any other, it is a small fish not 6 

 inches in length, and is rather rare I should say in Port Jackson. 



Two other species of Mugil have been described as coming from 

 this country, one Mugil breviceps, by Steindackner in the Proceed- 

 ings of the Academy of Sciences of Vienna in 1866, the other 

 Mugil gelatinosus by Klunzinger in the Archiv. fur Natur, for 1872. 

 I have never seen these descriptions, and I cannot recognize or 

 accopt them as species. If Naturalists are desirous of describing 

 the Fauna of this country iu publications in places so remote as 

 Vienna or Berlin, they might at all events transmit a copy of such 

 publications to one of the scientific societies of this place. 



Genus AGONOSTOMA, Gunther. 



Small teeth in one at least of the jaws, the lower lip with the 

 margin rounded not sharp.
