"-28 " THETIS " SCIENTIFIC RESULTS. 



Pterygotrigla is a new generic name substituted for Iloplonotus, 

 which is preoccupied. Nine new species are described ; these 

 are : — 



Dasyatis tJietidis. 

 Chimcera ogilhyi. 

 Anthias pulchellus. 

 Monacanthus setosus. 

 Sebastes thetidis. 

 Lejndotrigla modesta. 

 Parapercis octdaris. 

 Histiojiterus farnelli. 

 Paralichthys tenuirastrum. 



The following nine known species are for the first time recoi'ded 

 for the Colony, and those marked with an asterisk have not before 

 been recognised from Australia : — 



* Narciiie tasmaniensis, Richardson. 



Exoccetus evolans, Linnaeus. 



2Iacrorhamphosus scolopax, Linnaeus. 



Trachichthys elongatus, Giinther. 

 * Parat7'achichthys trailli, Hutton. 



Lagocephalus lunaris, Bloch. 



Amhlyrhynchohis oblongus, Bloch. 



Chilomycterus jaculifera, Cuvier. 

 '*Ichy thy Scopus inermis, Cuvier and Valenciennes. 



There are also a number of species not obtained since first 

 recorded; among these may be mentioned : — 



Creedia clathrisguamis, Ogilby. 

 Trachichthys elongatiis, Giinther. 

 Apogonops anomalus, Ogilby. 

 Epinephelus septein/asciatus, Thunberg. 

 JVovacuUchthys jacksoniensis, Ramsay. 

 Monacanthus mosaicics, Ramsay and Ogilby. 

 Centrojjercis nudivittis, Ogilby. 

 Synaptura fasciata, Macleay . 



Several others collected, although jDerhaps not I'ecoi'ded, are 

 known from additional specimens received at the Museum, and 

 are therefore excluded from the above list. 



All the new species have been figured, with the exception of 

 Dasyatis thetidis, Ogil., of which adult examples are not available, 

 and the type non-existent. My plan has been to illustrate all 

 species obtained, not previously figured ; this has been departed 

 from only in a few instances and where the specimens obtained 

 were immature or otherwise unsuited for delineation. On the 

 •other hand, some figures are published of species not obtained ;
