 richthya vermiculatua Poey. The type of Coryphcena pnttacua was sent from Charleston 

 by Dr. Garden, and it has been identified as a Xyrichlhya by Dr. Bean, who has exam- 

 ined it in London. Possibly another species of this type {Xyrichlhya venuatua Poey = 

 X. lincatna C. *&. V.) occurs with the preceding on our coasts.

 I.e., 367. Cape San Lucas. The subgenus, Iniiatiua (Gill, Proc. Ac. Nat. Sci. Phila., 

 1862, 145; type Xyrichthys j)«ro Cuv. & Val.) is distinojuished from Xyrichthys by tbe 

 prolongation and separation from the tin of the first two dorsal spines.

 The subgenus Dimalococentnia Gill (Proc. Ac. Nat. Sci. Phila., 1863, 223; type Xora- 

 culichthys calloaoma Bleeker), is distinguished from Xyrichlhya by the rounded (not 

 trenchant) anterior edge of the head, and by the partial separation of the first two 

 dorsal 8j)iue8 from the rest of the fin,

''SCARCS Forskal. 



The two groups Scarus {^Hemiatomn Swainson, aud I'scudoscarus Bleeker) and 

 Sparisoma (= Scarus Bleeker) are reallj' very distinct genera, each represented by 

 several species among the Florida Keys. They may be thus defined : 



SCAUUS Forskal. 

 ( CaHiofZon Gronow ; i/emis/o/HO Swainson ; Faeudoscarus Bleeker.) 

 (Forsk&l, Descr. Anim. Orientali Observ., 1775, 25; type Scarus psittacus Forskal, 

 Ac.) 



Lower i>haryngeal spoon-shaped, much longer than broad, transversely concave ; 

 teeth fully coalesced, divided in each jaw by a distinct median suture ; skull broad 

 above; gill membranes forming a fold across the narrow isthmus; dorsal spines flex-
