G. CHARYBDIA RHOMBOIDICHTHYS. 



Charyhdia rhomboidichthys Facciola, Nat. Sicil., 1885, 6 (Messina). 



Form, oval ; the two outlines similar; snout, obtuse, somewhat prom- 

 inent; teeth, insensible; eye, 4£ in head, the right a little above the 

 left; none of the dorsal rays prolonged; scales, cycloid, thin; lateral 

 line without arch; length 40 mm . D. 99, A. 74, V. 0. 



This form seems to be allied to Syacium and Arnoglossus. 



7. BIBRONIA LIGULATA. 



Bibronia Ugulata Cocco, I.e., 1844 (Messina). Facciola, Nat. Sicil., 1885,4 (Messina). 

 This form is known from specimens one-third of an inch in length. If 

 we suppose that in Symphurus the pectoral fins become atrophied with 

 age, this may well be the larva of Symphurus nigrescens. 



8. BASCANIUS T-S3DIFER. 



Bascanins tcedifer Schiodte, "Naturhist. Tydsskrift, v, 269, 1867" (Oceanic). 



We have not seen the original description of this form, but from the 

 references made to it by other authors it would appear to be a larval 

 Symphurus.
