17. CHELIDONICHTHYS KUMU (Lesson and Garnot). 



Two large specimens. We have compared these and numerous 

 specimens from Japan with three specimens from Australia. The 

 rostral processes are usual!}' a little more produced, makino- the snout 

 notched in front in the northern specimens and the interorbital space 

 slighth" less concave. The spots on the inner surface of the pectoral I 

 are variable in number and position. On one of the Australian speci- 

 mens the}'^ are scattered over the entire fin; in another the}^ are con- 

 fined to the lower half of the fin. In our Port Arthur specimens they 

 are scarcely evident. These differences are too slight to consider as 

 specific differences. 



Family HEXAGRAMMID^. 



18. HEXAGRAMMOS OTAKII Jordan and Starks. 



Several small specimens taken. 



Family SCORP^NID^. 



19. SEBASTODES FUSCESCENS (Houttuyn). 



Several small specimens preserved. 



20. TRACHIDERMIS FASCIATUS Heckel. 



» 

 ( Centridermichthys ansatus Richardson. ) 



One specimen. It agrees very well in all characters with specimens 

 from Kiusiu in fJapan. 



It is probable that the Chinese and Japanese species called an.satus'' 

 is the same as the original fasciatux. The latter was reported to be 

 from the Philippines but it is not likely that any cottoid fish occurs in 

 these tropical islands. 



Family PLATYCEPHALID^E. 



21. PLATYCEPHALUS INSIDIATOR (Forskal). 



Three specimens collected which have been compared with speci- 

 mens from Japan and found to be identical.
