r.--AM.M0DUs Ag. regarded as preoccupied by Psammodius, a genus of beetles, 



but the words are not from the same roots. 

 Demiurga Gistel. X; type (Rhina ancvlostoma B1. & Schn.). .\ substitute for 



KiiiNA Bon., etc., regarded as preoccupied by Rhina 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).

may perhaps be substituted.
