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 Tryyonobatus crassicaudatus, or of Agassiz's Trygori oblongus.

The holotype of this species forms part of the Gazola Collection 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 dor Padu- 

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

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

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



Regarding the type-specimen in the Paris Museum the same author re- 

 marks that the rostral region is incompletely preserved, and " von den Flossen
