I have not been able to convince myself that these specimens be- 

 long to different species. The large individuals from Madeira have 

 a small but very distinct patch of short cardiform teeth on the ante- 

 rior end of the palatine bones. These teeth are absent in the smaller 

 specimen from the Mediterranean, which in other respects perfectly 

 agrees with the Madeira fish, as far as it can be determined from a 

 single skin. If it should prove to be specifically distinct, the name 

 of Mora benoit may be applied to it, as Pharopteryx benoit is merely 

 the young state of that fish. The typical specimens of Ph. benoit are 

 from 10 to 18 lines long. 



The sl-eleton does not differ from that of Oadus, except in those 

 points which are dependent on the general external form. The 

 transverse processes of the abdominal vertebrae are elongate, although 

 shorter than the neural spines, and but slightly dilated ; the ribs are 

 feeble. The abdominal cavity is continued on to below the anterior 

 caudal vertebrae, terminating below the twenty-fifth vertebra. 



4. HALARGYREUS. 



Body elongate, covered with small scales. (A separate caudal) ; 

 two dorsal and two anal fins, the latter subcontinuous ; ventrals 

 composed of several rays. Jaws with a band of minute villiform 

 teeth of equal size ; no teeth on the vomer or the palatine bones. 

 No barbel. Branchiostegals seven ; pseudobranchise glandular, rudi- 

 mentary, covered by the membrane ; giU-rakers of the outer bran- 

 chial arch long. 



Madeira.
