NOTE ON iELURICHTHYS EYDOUXH AND PORICHTHYS POROSIS- 



SIMUS. 



By DAVID 8. JORDAN. 



In tlie fifteenth volnnie of the Histoire Naturelle des Poissons, page 

 43, Valenciennes describes, in a very brief and insufficient manner, a 

 Catfish from Guayaquil, under the name of GaJeichtJn/s eydouxii. Sus- 

 pecting that this species might be identical with ^lurichthys 'pinnimacu- 

 latus Steind., I wrote to Dr. H. E. Sauvage, of the Museum at Paris, 

 for information concerning the type of G. eydouxii. The following is a 

 translation from the letter received by me from Dr. Sauvage: 



"I have before me the type of Galeichthys eydouxii Cuv. Val., com- 

 ing from Guayaquil, through Eydoux. It is a fish of O'".22o in length, 

 the head 0"'.047, the breadth 0"'.()3o. The species is very near to ^/u- 

 richthys pinnimaculatus (Steindachuer Ichth. Beitr. TV, i>. 25, pi. VIII). 

 It is, however, distinct, and differs in the following points : 



"The head is broader in ^4. eydouxii ; the ventrals and the anal are 

 without spot; the anal is not emarginate in its median part, but cut 

 squarely. The principal difference is in the shield which precedes the 

 dorsal. In the species of Steindachuer this shield is narrow, in the other 

 it is as long as broad, the lateral edges being rounded. On the other 

 hand the shield which precedes this is more narrow than in A. pinni- 

 maculatus. 



"D. I, 7; A. 30; P. 1, 14. 



"Length of head 4f in total length; predorsal shield broad, rounded 

 on the edges, granulated and grooved. Teeth of the palate forming a 



* In the Proc. U. S. Nat. Mus. IH82, 608, we have retained for this species the name 

 of Platyglossns radiatus. This is an error. The Sparus radiatus of the twelfth edition 

 of the Systema Naturai, p. 472, received through Dr. Garden, from Charleston, is this 

 fish, as stated by us. In the tenth edition, p. 2d8, there is, however, a Labrus radiatus 

 based on Catesby's figure of the "Pudding wife," which is Platyglossus cyanostifjma. 

 The latter species must therefore be called Platyglossus radiatus, and the oldest tena- 

 ble name of the other seems to be hiviitatus.
