pl. xx. fig. 13. 
Galaxias alpinus, (part.) Smitt, Bih. Svenska Ak. xxvi. iv. 
Nong oa pao, plait OOM): 
Teeth in the jaws subequal, without distinct enlarged canines. 
Depth of body 5-6 in the length, length of head 44-437. Snout 
longer than eye, the diameter of which is 53-73 in the length of 
head, interorbital width 23-22. Jaws equalanteriorly; maxillary 
extending to below the middle of eye. 8 or 9 branchiostegals. 
11-13 gill-rakers on the lower part of the anterior arch. Dorsal 
IV 8; distance from origin of dorsal to base of caudal 33-32 in 
the length of the fish. Anal IV—V 10-11, commencing below the 
anterior part or middle of the dorsal, when laid back extending to 
the procurrent rays or base of caudal. Pectoral extending 2-4 of 
the distance from its base to the base of ventral. Ventrals 
7-rayed, originating at a point equidistant from cheek or pre- 
operculum and base of caudal or from middle or extremity of pectoral 
and origin of anal, extending 3-2 of the distance from their base 
to the origin of anal. Caudal truncate. Caudal peduncleas long 
or a little longer than deep. Head, body, and fins covered with 
numerous irregular dark spots.

The two large fishes, undoubtedly belonging to one species, from 
a lake in the province of Punta Arenas, Chile, described by 
Philippi (Verh. Deust. Wiss. Ver. Sant. Chile, iii. 1895, p. 19) 
under the names of Gialaxias grandis and G. delfini, agree with 
G. platei in the form and proportions of head and body, size of the 
eye, shape of the caudal, length of pectoral and ventral and size 
of the dorsal fin, and also in coloration. The unpaired fins are 
torn in the type of G. grandis, a fish of 330 mm., and the number 
of fin-rays in G. delfini is given as Dorsal 8, Anal 18. If it were 
not for this, I should have no hesitation in regarding this species 
and G. platei as the same. 
8. GALAXIAS SMITHII, sp. n. 
Lower jaw with distinct lateral canines, Depth of body 63 in 
the length, length of head 53. Snout slightly longer than eye, 
the diameter of which is 4; in the length of head, interorbital 
width 22, Jaws equal anteriorly; maxillary extending nearly to 
below middle of eye. 8 branchiostegals. 10 gill-rakers on the 
lower part of the anterior arch. Dorsal III-IV 9; distance from 
origin of dorsal to base of caudal 32 in the length of the fish. 
Anal IV 10, commencing below the anterior part of the 
dorsal, when laid back not extending to the caudal. Pectoral 
extending more than 4 of the distance from its base to the base 
of ventral. Ventrals 7-rayed, originating at a point slightly
