 pendant les annees 1832 et 1833. Congres Scientifique de France tenue a 

 Poitiers, 1834. 



M. DE LA PyLAIE (de FoUGERES). 



This singularly useless paper has been totally overlooked by all natural 

 ists except Dr. Gill, who has noted Pylaie's use of the name Argyrosomus 

 (1835), at a date prior to that of Agassiz (1850). Besides the "new genera" 

 enumerated below, the following new species are indicated by De la Pylaie : 



Spinax vitulinus p. 527 ("tete qui rappelle un muffle de veau"). 



ScYLLiUM atlanticum (527) ("trop dififerente," etc.). 



Scymnus aquitanensis (527) (la Senille ou Chenille de I'lle Dieu). 



Squalraja cervicata (527) ("pour le distinguer de I'ordinaire, que est acephale"). 



Squalraia acephala (527) ( = Squatina squatina). 



Torpedo elliptica (527) ("d'apres la structure de ses deux pectorales"). 



Rajabatis macrophalla (528) (Differing in length of clasper). 



Raj ABATIS MicROPHALLA (528). "Neuf autres especes completent ce genre; ce sont 



les R. triptera, polyacantha, variegata, tigrina, monolifera, florigera, 



melumpseca, mosaica, undulata. 

 Hippocampus atrichus (529) ("espece de I'Ocean"). 

 Hippocampus jubatus (529) ("des filamens qui composent, le long de son cou, une 



espece de criniere peu fournie") . 

 Aptocyclus ostraciodes (529). "Coffret." "Nouvelle espece encore tres bien carac- 



terisee."
