48 THE GENERA OF FISHES 



Thynnus Browne, 451; type "Thynnus bontii corpore crassiori et 

 BREVioRE etc., The Boneeto" = Scomber pelamys L. 

 This use of the name Thynnus is later than that of Fabricius, 1775, for a 

 genus of Insects. It antedates Thynnus of Cuvier and it is equivalent to Thyn- 

 nus of Liitken, a name later changed to Euthynnus by its author. Scomber 

 pelamys L., the Oceanic Bonito, is the Bonito of Cuba and Jamaica, where the 

 Northern Bonito, Sarda sarda, is unknown. Of the "Boneeto," Browne observes 

 that it is "a dry coarse fish, not much esteemed, though a hearty wholesome food." 

 Should stand as Euthynnus Liitken. Monotypic. 



Saurus Browne, 452 ; type "Saurus argenteus cute longitudinalis 

 etc., the Leather Coat" ^ Scomber saurus Bloch & Schneider = 

 Oligoplites saurus of authors. 

 Not Saurus Cuv. & Val., which is Synodus Gronow. If Browne's names are 

 accepted, Saurus must replace Oligoplites Gill, its type species standing as 

 Saurus saurus (Bloch & Schneider). Two other species of Saurus are enum- 

 erated by Browne, the "Red-tailed Jack" and the "White-fish." 



Teuthis Browne, 454; type "Teuthis fusca c^ruleo nitens, the Doc- 

 tor (TuRDUs RHOMBOiDES Catesby) " :^ Ch^todon c^ruleus 

 Bloch. 



The first application of the name Teuthis (xeijdi;, a squid) to a fish is that 

 of Browne in 1756. Linnseus in 1766 accepted Browne's name Teuthis, and sub- 

 stituted it for Gronow's name Hepatus, 1763. The republication of Teuthis in 1789 

 would help to fix the generic name Teuthis with Browne's original species. 

 Hepatus Gronow was primarily based on a specimen of the West Indian species 

 called Ch^todon chirurgus by Bloch, with which Ch^todon ceruleus Bloch, the 

 type of Teuthis, is strictly congeneric. The other species concerned, Teuthis 

 javus L., wrongly referred by Gronow to Hepatus, should stand as Siganus For- 

 skal. Cuvier and Valenciennes, according to Giinther, were in error in referring 

 Gronow's specimen, the type of Teuthis hepatus L., to an East Indian species, 

 since called Colocopus lambdurus Gill. 



The four species entangled in the confusion superimposed upon Browne, should, 

 as Gill has shown, stand as follows : 



Hepatus or Teuthis C/Eruleus (Bloch & Schneider). 



Hepatus or Teuthis hepatus L. 



Colocopus lambdurus Gill. 



Siganus javus (L.). 

 Rhomboida Browne, 455; type "Rhomboida alepidota argentea pin- 

 Nis oMNis BREviBUS, the Silver-fish" = VoMER browni Cuv. & 

 Val., 1833. 



The generic name Rhomboida antedates that of Vomer Cuvier, and, if ac- 

 cepted, the type species would stand as Rhomboida browni (Cuv. & Val.) = 

 Platysomus spixi Swainson, a species distinct from the northern Vomer setipin- 

 Nis (Mitchill). 



Under Rhomboida, Browne mentions also "Rhomuoida major alkpiduta, the 

 Larger Silver-fish, with long fins (Zeus cauda bifurca Artedi)." This must be
