 4^ to 6 in the length of head, interorbital width 5-^- to 6. Lower jaw rather prominent; 

 maxillary extending to below anterior part or middle of eye ; cheeks, opercles, and

 anterior arch. Dorsal VI-VII, 32-34. Anal 31-34. Pectoral from less than 

 I to more than f the length of head, usually longer than pel vies, which seldom 

 reach the anal. Caudal rounded. Caudal peduncle deeper than long. 62 to 

 78 scales in a longitudinal series from above base of pectoral to caudal fin, 41 to 48 

 in upper lateral line, which ends below or a little behind end of dorsal fin, 6 to 11

Chile ; Magellan Straits ; Falkland Islands. 



Here described from several examples, 140 to 250 mm. in total length, from the 

 Falkland Islands, Magellan Straits, and Chile, including the types of the species and 

 specimens from Station 118, Port Stanley, Falkland Islands, collected by the Scotia. 

 In young specimens {N. veitchii, N. hrevipes) the interorbital width is ] or ^r the length 

 of head. 



(5) Notothenia wiltoni, sp. n. (PI. VII. fig. 2.) 



Depth of body 4| to 5-^ in the length of the fish, length of head S^ to 3|. 

 Diameter of eye 3| to 4f in the length of head, interorbital width 6 to 7. Jaws equal 

 anteriorly ; maxillary extending to below anterior ^ of eye or beyond ; cheeks, opercles, 

 and upper surface of head, except snout, scaly; 16 to 19 gill rakers on lower part of 

 anterior arch. Dorsal VI-VII, 33-36. Anal 32-34. Pectoral | or f the length of 

 head ; pelvics as long or somewhat longer, extending to vent or to anal fin. Caudal 

 rounded or subtruncate. Caudal peduncle deeper than long, its least depth | to ^j the 

 length of head. 62 to 70 scales in a longitudinal series from above base of pectoral 

 to caudal fin, 47 to 54 in upper lateral line, which almost reaches caudal, 7 to 14 in 

 lower lateral line. Body with irregular dark cross-bars ; spinous dorsal dusky, pale 

 at base. 



Ten specimens, 125 to 250 mm. in total length — one from Orange Bay (Paris Mus.) ; 

 another from the Straits of Magellan (Coppinger) ; the others taken by the Scotia at 

 Port Stanley (Station 118) and Port William (Station 349), Falkland Islands (shore,' 

 51° 41' S., 57° 51' W,), and on the Burdwood Bank (Station 346, 54° 25' S., 57° 32' W., 

 56 fathoms ; surface temperature 41"8° F. ; otter trawl; 1st December 1903). 



This species is named after Mr D. W. Wilton, zoologist of the Scotia.
