BOTHIDyE (or PLEURONECTID.E). 



Regan makes the Bothidae a family distinct from Pleuronectidae. 



Platophrys pantherinus Ruppell. Darnley Island. Scales subquadrate, 

 about 1-1£ mm. long, the basal middle more or less extended, and the laterobasal 

 corners ill-defined; circuli very dense; radii basal and lateral, very fine and 

 numerous. The scales of the upper (coloured) side are strongly ctenoid, with a 

 single row of about 18-23 long sharp teeth. Those of the blind side are cycloid, 

 with circuli and radii crossing in the apical field, forming an irregular cancella- 

 tion. In my key to Pleuronectid scales (Proc. Biol. Soc. "Washington, Oct. 31, 

 1911) this runs straight to Platophrys, and falls with P. const ellatus, from which 

 it differs by the generally longer scales. All Platophrys examined have the 

 eancellate structure in the apical field. The species differ in the number of 

 marginal teeth on the ctenoid scales; thus in P. podas they are not nearly so 

 numerous as in P. pantherinus. 



SOLEID^E. 



Aserragodes macleayanus Ramsay. Queensland. Scales elongate, about 

 2 mm. long and 1 broad ; nucleus subapical ; circuli dense ; radii very numerous, 

 though not so dense as in Platophrys pantherinus ; ctenoid patch well developed ; 

 marginal teeth very large, usually 9, sometimes fewer, structure of ctenoid area 

 •practically as in Aphoristia, not at all as in Achirus, though the genus has been 

 referred to the Achirinse. The radial system also is wholly unlike that of 

 -Achirus, but does resemble that of Aphoristia.
