Synonymy af species of Bibronie. 
1. DELOTHYRIS PELLUCIDUS. 
Thyris pellucidus Goode, Proc. U.S. Nat. Mus., 1880, 337, 344, 475. (Gulf Stream, off 
Rhode Island). Jordan & Gilbert, Synopsis Fish. N. A., 1882, 840 (copied). 
Delothyris pellucidus Goode, Proc. U. 8. Nat. Mus., 1883, 110. 
This fish is unquestionably a larval form, but probably the adult is 
not yet known. In some respects it resembles Monolene, in others it 
seems allied to the Cynoglossine. The type was nearly three inches in 
length. 
2. COCCOLUS ANNECTENS. 
Coccolus anneciens (Bonaparte) Cocco, |. c., 1844 (Messina). 
This species has not yet been described in detail, but from the form 
of the body it would seem to resemble most closely the young of Plato- 
phrys podas. 
3. PELORIA HAICEELI. 
Peloria heckeli Cocco, 1. c., 1844 (Messina). Emery, Contribuzione all’ Ittiologia, 
405 (Naples). Facciola, Nat. Sicil., 1885, 5. 
The specimens of this species described by Facciola are 20 to 36 ™™ 
inlength. According to Facciola,* it can be confounded with no known 
species of Pleuronectoid. Dr. Emery has maintained that it is the 
young of Platophrys podas, and his figure and description seem to ren- 
der this determination almost certain. 
4. CHARYBDIA. (Species.) 
Peloria riippeli Emery, Contribuzione all’ Ittiologia (Naples). 
The description given by Dr. Emery of P. riippelli diverges so widely 
from that given by Dr. Facciola, that the identity of the two may be 
questioned. If, as is possible, the pectorals in the achirous forms dis- 
appear with age, this species may belong to the Cynoglossine. More 
likely, it is a relative of Arnoglossus, or of Monolene. 
5. CHARYBDIA RUPPELLI. 
Peloria riippelli Cocco, |. c., 1844 (Messina). 
Charybdia riippelli Facciola, Nat. Sicil., 1885, 5 (Messina). 
This is probably the young of some species as yet unknown in the 
adult condition. Some of its characters suggest Arnoglossus ventralis. 
According to Facciola, the body is naked; the form oval; the mouth 
as long as the eye;.right eye higher than left; first dorsal ray only 
prolonged; no scales; left ventral with its base longer than the right; 
length 30 to 40™™. D.113, A. 91.. 
*“Non 8 a dubitarsi che questi Pleuronettidison giovani di altro specie pid grandi. 
Diro soltanto che la Peloria heckeli non puo confondersi con nessun Pleuronettide 
conosciuto.” (Iacciold.) ;
