Depth of body 6 to 6^ in the length, length of head about 4. Snout longer than eye, 

 diameter of which is 7! to nearly 8 in length of head; interorbital width about 5 \. 

 Maxillary extending to well beyond eye. Length of pectoral about twice in that of 

 head. Back and sides as well as lower parts and the greater part of the abdomen 

 chocolate brown or blackish, with conspicuous hieroglyphic-like white markings over 

 the whole of the body and the fins ; posterior part of pectoral with a narrow white border. 



Hob. Coasts of Chile and Peru. 



There are 3 specimens (290-480 mm.) in the British Museum collection from Chile, 

 2 of them received from Mr Cavendish Bentinck. 



Many writers on Chilean and Peruvian fishes have identified the " Congrio negro" 

 as G. chilensis, and the "Congrio Colorado" as G. blacodes. There appears to be little 

 doubt that the form with a short body, broad interorbital region, rather long and 

 pointed pectoral fin, and with the large and characteristic white markings, is that figured 

 by Tschudi as Ophidium maculatum, but this is usually identified with Conger chilensis 

 of Guichenot. The latter is inadequately described to enable the fish to be identified 

 with certainty, but the description seems to apply more nearly to the " Congrio Colorado ", 

 and, pending a re-examination of the type, the name chilensis may be used for this 

 species. G. nigricans, Philippi, is almost certainly identical with G. maculatus. Owing 

 to the confusion between the two Chilean and Peruvian species it has proved impossible 

 to give full synonymies of these.
