PISCES. 125 



Macrurus BLOCK, Lepidoleprus Risso. Head and body covered 

 with scales mostly carinate or spinose on the posterior margin. 

 Snout produced over the mouth ; mouth inferior. Numerous small 

 teeth in intermaxillary bone and lower jaw; lingual and palatine 

 teeth none. Cirrus under chin. Branchiostegous membrane with

Sp. Macrurus Fdbricii SUNDEV., Coryphcena rupestris FABR., BLOCH Ichih. 

 Tab. 177, from Greenland, with scales sharply carinate ; Macrurus Stro- 

 emii REINH., Coryphcenoides rupestris GUNNERUS, with flat scales having fine 

 spines at the posterior margin ; on the coasts of Norway. A very similar 

 species occurs in the Mediterranean Sea, Lepidoleprus codorhynchus BiSSO, 

 BONAP. Faun. Ital. ni. PL 123, fig. i. 



In other species the snout is more prolonged and pointed ; as in Lepido- 

 leprus trachyrhynchus Risso, Ichih. de Nice, PL 7, fig. 21, and a very 

 similar species from Japan, Macrurus japonicus SCHLEGEL, Faun. Japan. 

 Pise. Tab. 112, fig. 2. These fishes appear to reside at great depths in 

 the sea.

Ateleopus SCHLEGEL. Scales inconspicuous or none. Head pro- 

 duced beyond the mouth, obtuse ; mouth protractile, inferior. Teeth 

 small, crowded in intermaxillary bone and lower jaw; teeth in 

 palate and vomer none. Cirri none. Branchiostegous membrane 

 with eight rays. Ventral fins placed in front of pectoral, consisting

 small caudal. 



Ateleopus Schlegdii nob., Fauna Japonica, Pise. Tab. 112, fig. 2; the 

 only known specimen of this rare Japan fish was 2' 2" long. The genus 

 Ateleopus appears to stand between Macrurus and the sub-genus Brotula 

 (under Gadm) ; of the internal structure nothing is known. 



Gadus L. Head smooth. Body covered with scales mostly very 

 small, circular, entire at the posterior margin. Teeth conical, nume- 

 rous in intermaxillary bones, in lower jaw and in vomer. Bran- 

 chiostegous membrane with seven rays. Ventral fins jugular, acu- 

 minate. Mostly several dorsal and anal fins.

 northern countries constitute the chief food of man, and form when
