204 THE GENERA OF FISHES,, PART II 



Cyclopium Swainson, II, 305; haplotype Pimelodus cyclopum Humboldt = Cy- 

 CLOPiuM HUMBOLDTi Sw. Replaces Stygogenes Gthr. (1864). 



Clupisoma Swainson, II, 306; haplotype Silurus garua Ham., Clupisoma ar- 

 GENTATA Sw. Replaces Schilbeichthys Blkr., 1858. 



Pachypterus Swainson, II, 306; logotype Silurus atherinoides Bloch. Preoccu- 

 pied in Coleoptera (1833) ; replaced by Pseudeutropius Blkr. (1863). 



Pusichthys Swainson, II, 307; haplotype Schilbe uranoscopus Rijppell. A syno- 

 nym of Schilbe Cuv. (1817). 



Cotylephorus Swainson, II, 308; haplotype Platystacus cotylephorus Bloch — 

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

 (Scopoli). 



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

 Preoccupied in mollusks; gives way to Rhamdia Blkr. (1858). 



Diacantha Swainson, II, 310; logotype Diacantha zebra Sw. = Cobitis geto 

 Ham. (pi. 11). A synonym of Botia Gray, 1831. 



Canthophrys Swainson, II, 310; logotype Canthophrys albescens Sw., based on 

 Cobitis No. 3, Hamilton. Said by Swain to be a species of Botia Gray (1831). 



Acoura Swainson, II, 310; logotype Cobitis savona Ham. (Acoura obscura Sw.). 

 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 tubes Cuv. A syno- 

 nym of Sphyrna Raf. 



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

 MoBULA Raf. 



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

 of Ostracion L. 



Rhinesomus Swainson, II, 324 ; logotj'pe Ostracion triqueter Bloch. A synonym 

 of Lactophrys Sw. 



Lactophrys Swainson. II, 324; logotype Ostracion trigonum L. 



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

 of Aracana Gray. 



Rhinecanthus Swainson, II, 325 ; logot3'pe Balistes ornatissimus Lesson = Bal- 

 istes aculeatus L. a synonym of Balistapus Tilesius. 



Zenodon (Riippell) Swainson, II, 194, 325; orthotype Balistes Niger Lac. This 

 name Zenodon, being ascribed to Riippell, 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), Erythrodon 

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

 Xenodon. 



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

 vetula L. a synonym of Balistes L. 



Canthidermis Swainson, II, 325 ; logotype Balistes angulosus Q. & G. 



Melichthys Swainson, II. 325; logotype Balistes ringens Osbeck (not of L.). 

 Name changed to Melanichthys by Gthr. (1870). 



Capriscus (Willughby) Swainson, II, 326; logotype B.\listes ervthropteron 

 Lesson : a svnonvm of Balistapus Tilesius.
