GisTEL, 1848 237 



Proscinetes Gistel, X; type Microdon elegans Ag. (fossil). Substitute for 



MiCRODON Ag., preoccupied ; replaces Polypsephis Hay, 1899, which is also a 



substitute for Microdon. 

 Periergus Gistel, X; type Microps furcatus Ag. (fossil). A substitute for 



MicROPS Ag., preoccupied in beetles. 

 Arnion Gistel, X; type (Mugil cephalus L.). A substitute for Mugil L. for no 



assigned reason. 

 Myrmillo Gistel, X ; orthotype Mustelus vulgaris. .\ substitute for Mustelus 



Cuv., regarded as preoccupied by Mustela L. Same as Pleuracromylon Gill. 

 Analithis Gistel, X; orthotype Platyrhina sinensis (B1. & Schn.). Substitute 



for Platyrhina M. & H., regarded as preoccupied by Platyrhinus, replaced 



by DiscoBATUs Garman (1881). 

 Strotes Gistel, X; type (Stromateus gibbosus Blainv.). Name a substitute for 



Platysomus Ag. preoccupied by a genus of beetles. 

 Abron Gistel, X ; orthotype Silurus lima Ag. A substitute for Platystoma Ag., 



1829, preoccupied in insects. 

 Plectrostoma Gistel, X; type Oxyrhina mantelli Ag. (fossil). Substitute for 



Oxyrhina Ag., preoccupied. A synonym of Isurus Raf. 

 Euporista Gistel, X ; type Pleuronectes plagiusa L. A substitute for Plagusia 



Bon., preoccupied; a synonym of Symphurus Raf. 

 Deportator Gistel, X; type (Silurus anguillaris Forskal). Name a substitute for 



Plotosus Lac, needlessly regarded as preoccupied by Plotus L. 

 Alazon Gistel, X; orthotype (Pcecilia vivipara). A substitute for Pcecilia 



Cuv. & Val., regarded as preoccupied by Pcecilus Bon., a beetle. 

 Apodometes Gistel, X; type (Psammodus rugosus Ag., fossil). A substitute for 



PsAMMODUS Ag. regarded as preoccupied by Psammodius, a genus of beetles, 



but the words are not from the same roots. 

 Demiurga Gistel, X; type (Rhina ancylostoma B1. & Schn.). A substitute for 



Rhina Bon., etc., regarded as preoccupied by Rhtna Olivier (1807), a 



genus of beetles. But this genus of rays was called Rhina in 1801, by 



Bloch & Schneider. The same name was used by non-Linnaean writers 



in place of Squatina. For this purpose it was first binomially used in 1810. 



If Rhina is used for Squatina, Demiurga could replace it for this genus, 



instead of Rhamphobatis Gill (1861). 

 Prenes Gistel, X; type (ChvEtodon argus Bloch). Name a substitute for Sca- 



tophagus Cuv., regarded as preoccupied by Scatophaga. Has priority over 



Cacodoxus Cantor, 1849. 

 Agoreion Gistel, X; type Acanthoderma spinosum Ag. (fossil). Name a sub- 

 stitute for "Scleroderma Ag.", used in fungi, also as Sclerodermus in bees, 



but I find no Scleroderma in Agassiz. It was probably the preoccupied 



name, Acanthoderma Ag., which Gistel had in mind ; for this Agoreion 



may perhaps be substituted. 

 Creotroctes Gistel, X ; type Scomber sarda L. Name an unexplained substitute 



for Sarda Cuv. It is a synonym of Palamita Bon., offered in 1832 as a 



substitute for Pela.mys Cuv. & Val.. 1831, which is the same as Sarda Cuv., 



1829. 

 Denius Gistel, X; type (Sparus sakgus L.). Name a substitute for Sargus Cuv.. 



preoccupied. A synonym of Diplodus Raf. 

 Borborodes Gistel, X; type (Squalus lichia Cuv., Squalus lichia Bonnaterre). 



Substitute for Scymnus Cuv.. preoccupied in beetles. A synonym of Scym- 



norhinus Bon., 1846.
