NO. 2133. FISHES TAKEN BY "ALBATROSS," 1888— THOMPSON: 433 



Upper lateral line terminating mider fourth from last dorsal ray 

 and two scale series before beginning of lower. 



Scales present on head only on upper half or third of cheeks, dorsal 

 surface of head naked, but covered by coarse papillae as far forward 

 as anterior edge of eyes ; no naked area before ventrals ; scales smooth 

 to touch because of pronoimced dermal flap which covers ctenoid 

 edges of scales, more particularly in adults. 



Color miiform; fins all more or less dusky, without pattern save 

 for three or four indefinite longitudinal lines anteriorly on second 

 dorsal, better defined in yomig; ventrals frequently much darker 

 above than other fins. According to Lonnberg ^ the hfe colors are: 

 '^Riicken dmikel graugriin, nach dem Bauch in Gold iibergehend, 

 miter dem Kopfe weiss." 



This species might well be NototJienia mageUanica (Bloch and 

 Schneider) were the anal rays not given as 25 for that form. 



Regan - beheves that Notothenia 7nacrocephala is identical with 

 species from Kerguelen, New Zealand, Auckland, and Campbell 

 Islands. This would leave this species and N. cornucola the sole 

 members of the genus which are circumpolar in distribution. His 

 decision with regard to N. cornucola seems to have been based on a 

 single "small specimen" from New Zealand. In his description of 

 N. macrocephala ^ the range of variation of the dorsal spines is given 

 as III to VI, which is greater than in any other species in the present 

 collection. In over a hundred examples of Notothenia tessellata the 

 number varied only between VI and VII, while in 75 of N. longipes 

 but 3 were found to vary from VI, and in 30 of N. sima the only num- 

 bers found were V or VI. However, judging from the form of the 

 species, it is not as strictly littoral as some of the others, and if any of 

 them are of wide distribution it would be this species, instead of cot- 

 toid forms like N. sima. If this distribution is adopted, the synonymy 

 would include the following, as given by Regan:

Without these locaHties, N. macroceyhala ranges from the Falk- 

 land Islands, through the Straits of Magellan, around Cape Horn, to 

 Fortune Bay, west coast of Patagonia and Otter Bay, in Smyth Chan- 

 nel, thus being present on both coasts.
