interpreted as referring to the remarkable pectinate form 

 of the fins.* The dimensions given (" trois decimetres "), 

 unless a misprint, indicate a much larger form than any 

 Cteiiopteryx hitherto recorded. We are, on the whole, 

 disposed to agree with Jatta in regarding Ruppell's species 

 as a doubtful form, the fate of which can only be decided 

 when further material is available. 



Summary. 



We conclude that Ctenopteryx cyprinoides, Joubin ('94), 

 is to be regarded as a synonym of C. fimbriatus, Appellof 

 ('90). C. {CalHteuthis) nevroptera., Jatta ('96), is also 

 probably to be referred to C. fimbriatus, but pending 

 further evidence Jatta's specific name is retained. Sepio- 

 teuthis sicula, Riippell (Verany '51), which has also 

 been considered to be identical with Appellof's species, 

 is a doubtful form, the position of which cannot at present 

 be determined with certainty.
