for whicli thfe Recorder has retained this name, and which is distinguished by 
its minute teeth, hut it will be another of the subgeneric divisions into which 
Pleuronectes has been split. Girard has described the teeth of Parophrys 
vettdus and Pleuronichthys romosus. as minute or inconspicuous, which is the 
reason why the Recorder referred them to his genus Parophrys : on the other 
hand, in the description of Pleuronichthys guttulatus no mention is made of 
the dentition ; and aS other characters clearly indicated its close affinity to 
Pleuronectes digrammus, it was placed along with this species. 
V Euchalarodus is a new genus established by Mr. Gill, Proc. Acad. Nat. Sc. 
Philad. 1864, p. 221, and distinguished from Pleuronectes and Jleteroprosopon 
{=Parophry$, Gthr., not Girard) by having the teeth uniserial, moveable, 
reclining inwards, compressed and constricted near the apex. Eu. putnami^ 
sp. n., from the coast of Massachusets. 
Mr. Gill (1. c. p. 216) has proposed some other generic names, viz., TJopsetta 
j for Platcssa glabra (Storer, in Best. Proc. i. p. 130, and in Mem. Amer. Ac. 
viii. p. 303, pi. 31. fig. 1) ; Pomatopsetta for Platessa dentata (Storer) ; and 
Lophopsetta for Pleuronectes maculatus (Mitchell). On the other hand Ere- 
panopsetta (Gill) is considered a synonym of Hippoglossoides.

Dr. Gunther has had the good fortune to examine the fishes 
of this family at a time when the numerous typical specimens 
of Dr. Bleeker^s collection were united with that of the British 
Museum, in which already numerous types had been accu- 
mulated. His researches led him to a complete systematic re- 
arrangement of the family, in which he endeavoured to keep 
naturally allied forms together, whereas Dr. Bleeker had fol- 
lowed a more artificial method. The genera adopted or pro- 
posed by Dr. Bleeker (186) are reduced to 114, some of which, 
moreover, were unknown to him. We cannot here repeat the 
characters on which the subfamilies, groups, and genera have 
been founded, and must be satisfied with indicating the arrange- 
ment merely by an enumeration of the divisions (Fish. Y. 
pp. 1-277)
