472 DR. R. O. CUNNINGHAM ON THE REPTILES, 
25. MAYNEA PATAGONICA, Sp. n. 
D.115. A. 85. 
Diameter of interorbital space a little less than that of orbit. Head less than + of the 
total length. Dorsal commencing a little in front of the base of the pectoral. 
Colour reddish purple, with minute white dots produced by the imbedded scales. 
Hab. The Otter Islands, in Smythe's Channel. 
This fish, which I have Dr. Günther's authority for regarding as the type of a new 
genus, I have named after my friend Captain R. C. Mayne, the head of the Magellan 
Survey, as a slight acknowledgment of the ready kindness which he ever displayed in - 
affording me opportunities for prosecuting my investigations during the three Jo in 
which I was associated with him. 
GADIDE. 
26. ohne Gayt, Guich. 
2.32] 86:24:37 (12). 
Eyes large, their long diameter nearly a third of the space between the orbits. Teeth 
in upper and lower jaws smaller and placed more widely apart than in M. vulgaris. 
Second dorsal deeply notched in the middle, the rays of the posterior third the largest. 
Anal deeply notched, appearing at first sight as if composed of two distinct fins. 
A good many specimens of this fish (which there seems little reason to doubt is the 
Merluccius Gayi, Guich., described at p. 328 of the second volume of the Zoologia, and 
figured in the Atlas Ictiol. lam. 8. fig. 2 of Gay’s Historia Fisica y politica de Chili) 
were taken, with fishing-lines, at the eastern entrance of the Strait of Magellan; and the 
above diagnostic description is drawn up from a small specimen which I preserved. The 
figure in the Atlas to Gay's History of Chili does not correctly represent the form of the 
dorsal and anal fins, there being no indication given of the marked manner in which they 
are cleft. It is probable that this was the ** Gadus" taken by Captain King off Cape 
Fairweather in 1826*, by Skyring in the Messier Channel in February 1830+, and by 
Fitzroy in Good-Success Bay in February 18331. 
PLEURONECTID X. 
27. PLEURONECTES, sp. 
A very young specimen of a Pleuronectes, which possibly may be P. umbrosus, 
Girard, was taken in Coquimbo Bay. 
SILURIDA. 
28. LORICARIA VETULA, Val. 
A good specimen of this species, taken in the River Plate, which previously did not . 
exist in the British-Museum collection, was given to me in August 1867. 
STOMIATIDÆ. 
29. oros NIGER, Rich. 
A specimen of this species was depen in the towing-net, between St. Vino and Rio 
de Janeiro.
