It seems desirable to give the complete synonymy of this species, as there is 

 no possible reason for doubting that all of the rays described under the various 

 names cited above belong to a single species. There is no specimen at the 

 Paris Museum which can be certainly identified as the type either of de Blaiu- 

 ville's Trygonobatus crassicaudatiij?, or of Agassiz's Tryijon oblongus.

The holotype of this species forms part of the Gazola Col]e<'.tion in Paris, 

 and another specimen slightly smaller than the type is preserved in the Uni- 

 versity of Padua Museum. An outline figure of the latter is given by Jaekel, 

 and likewise the following description : — 



" Was nun schliesslich das kleinere, vorstehend abgebildete Exemplar der Padu- 

 aner Sammlung betrifft, so ist dasselbe fast voUstiindig erhalten, also wesentlich 

 besser, als das von Volta abgebildete und von Agassiz als Galeus cuvieri bezeich- 

 nete. . . . Die Brustflossen sind schlank, fast sichelformig riickwarts gekriimnit."
