'ENDEAVOUE" SCIENTIFIC RESULTS 



band, which is rather wider than the row of scales it covers, 

 is uniformly dotted with minute brown specks, and may or 

 may not be defined by a black line above. Occiput darker. 



Described from three specimens 75 to 85 mm. long from twa 

 stations — Spencer's Gulf, South Australia, 20 fathoms, and 

 the entrance to Oyster Bay, Tasmania. Selected type 75 mm. 

 long from the latter locality. 



This is distinguished from all other Australian species by 

 its very small scales. It is apparently nearest to A. hep- 

 setoides, Richardson, ^ but the description of that species is 

 so imperfect I am unable to compare it satisfactorily. 

 Richardson, however, compared his species with A. hepsetus, 

 Linn., to which, as his name denotes, he considered it very 

 similar. The "Endeavour" specimens are so very different 

 in appearance from the latter that I have little doubt they 

 are distinct from Richardson's species also, and this, together 

 with the fact that they come from somewhat deep water 

 induces me to describe them as new. 



Genus T.-eniomembras, Ogilby. 



TcBniometnbras, Ogilby, Proc. Linn. Soc. N.S. Wales, xxiii.. 

 1898, p. 41. 

 Ogilby has erected this genus for Atherina microstoma, 

 Giinther, considering that it differs from Atherina by (i) its 

 more elongate body, (2) pointed snout, (3) small mouth, (4) 

 stronger dentition, (5) shorter, stouter and fewer gill-rakers. 

 I regard i, 2 and 4 as being of specific value only, but 3 and 

 5 may perhaps be conveniently used to split up the large 

 number of Australian species of Atherina. Notwithstanding 

 Giinther's statement, "teeth conspicuous in the jaws and on 

 the vomer," Ogilby describes the latter as smooth, while he 

 finds a single row on the palatines. These are lacking in the 

 specimens described below, but the vomerine teeth are wel' 

 developed.
