M. de la Pylaie (de Fougeres). 

 This singularly useless paper has been totally overlooked by all natural 

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

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

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



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



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



Scymnus aquitanensjs (527) (la Senille ou Chenille de I'llc Dieu).

SguALRAiA acephala (527) ( = Squatina squatina). 



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



Rajabatis mackophall.v (528) (Differing in length of claspcr). 



Rajabatis microphalla (528). "Neuf autres especes completent ce genre; ce sont 



les R. TRIPTERA, POLYACANTHA, VARIEGATA, TIGRINA, MONOLIFERA, FLORIGERA, 

 MELUMPSECA, MOSAICA, undulata.
