[105] FLOUNDERS AND SOLES. 329 



Synonymy of specie* of Bibronice. 



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). 

 Deloihyris pellucidus Goode, Proc. U. S.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 Cynoglossince. The type was nearly three inches in 

 length. 



2. COCCOLUS ANNECTENS. 



Coccolus annectens (Bonaparte) Cocco, I.e., 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 H<ffiCKELI. 



Peloria hceckeli Cocco, 1. c, 1844 (Messina). Emery, Contribnzioue all' Ittiologia, 

 405 (Naples). Facciola, Nat. Sicil., 1885, 5. 



The specimens of this species described by Facciola are 20 to 36 mm 

 in length. According to Facciola,* it can be confounded with no known 

 species of Pleurouectoid. 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 riippelli Emery, Contribuzione all' Ittiologia (Naples). 



The description given by Dr. Emery of P. rilppelli 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 Cynoglossince. More 

 likely, it is a relative of Arnoglossus, or of Monolene. 



5. CHARYBDIA RUPPELLI. 



Peloria riippelli Cocco, 1. 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 mm . D. 113, A. 91. 



*"Non e adubitarsi chequesti Pleuronettidi son giovani di altro specie piu grandi. 

 Diro soltanto cbe la Peloria hceclceli non puo confondersi con nessun Pleuronettide 

 conosciuto." (Facciola.)
