 C. BLOCHi Sw. A synonym of Platystacus Bloch, and of Aspredo (Gronow) 

 (Scopoli). 



Pteronotus Swainson, II, 309; haplotype Heterobranchus sextentaculatus Ag.

 A synonym of Nemacheilus Van Hasselt ; spelled .Acourus on an earlier 

 page. 



Somileptes Swainson II, 311; logotype S. bispinosa Sw. = Cobitis gongota Ham. 

 A synonym of Cobitis L., 1758. 



Platysqualus Swainson, II, 311; logotype Squalus tiburo Sw. (not of L.), 

 based on a figure by Russell, representing Sphyrna tudes Cuv. A syno- 

 nym of Sphyrna Raf. 



Pterocephala Swainson, II, 321 ; haplotype Raja giorna Lac. A synonym of 

 Moeula Raf. 



Tetrosomus Swainson, II, 323 ; haplotype Ostracion turritus Forskal. A section 

 of Ostracion L. 



Rhinesotnus Swainson, II, 324; logotype Ostr.\cion triqueter Blocli. .•\ synonym 

 of Lactophrys Sw. 



Lactophrys Swainson, II, 324; logotype Ostracion TRit;()NUM L. 



Platycanthus Swainson, II, 324; haplotype Ostracion auritus Shaw. A synonym 

 of Akacana Gray. 



Rhinecanthus Swainson, II, 325; logotype Balistes ornatissimus Lesson = Bal- 

 isTKs aculeatus L. a synonym of Balistapus Tilesius. 



Zenodon (Riippcll) Swainson, II, 194, 325; orthotype Balistes nicer Lac. This 

 name Zenodon, being ascribed to Riippcll, is probably a careless misprint of 

 Xenodon Riippell. Preoccupied in reptiles by Xenodon Boie, 1827. The name 

 is spelled Zenodon on page 194 also. Zenodon is, however, accepted by 

 Fowler (1904). If adopted, it replaces Odonus Gistel (1848), Erytiirodon 

 Ruppell (1852) and Pyrodon Kaup (1855') — all substitutes offered for 

 Xenodon. 



Chalisoma Swainson, 11, 325; logotype Balistes pulcherrimus Lesson = Balistes 

 vRTii.A L. A synonym of Balistes L.
