3. Notothenia karlandreae * n. sp. 



(PI. IV li- 13.) 



2 specimens from stat. 53, Port Williams, Falklands, depth 12 m., sand and 

 gravel. 3d of Sept. 1902. 



3 specimens from stat. 54, Port Stanley, Falklands, depth 10 m., mud and shells. 

 3d of Sept. 1902. 



D. VI, 28—30. A. 28—29. Sq. about 46. 



Head broad, rather strongly depressed, its width being 3/4 of its length, the latter 

 contained about 3V3 times in total length without caudal. Anterior portion of body 

 depressed, posterior compressed, its depth about 5 to 5 "/a times in total length 

 without caudal. Diameter of eye a little more than 4 times in length of head in 

 adult specimens, only 3V3 times in small specimens. Snout broad, rounded, equal 

 to diameter of eye in young specimens, a little longer in the adult. Interorbital 

 width 6^ 1 2 to 7 times in length of head. Maxillary extending to below anterior 

 third or fourth of eye. Lower jaw not ])rojecting. Scales on body rather large, 

 ctenoid, on head smaller and weaker, but covering opercles, occipital region and 

 posterior part of interorbital space (in young specimens the scales of the head are 

 still less developed). Lower side of head, preorbital and snout to behind nostrils 

 and anterior part of interorbital space naked. Second dorsal rather high, its longest 

 rays about ''U of length of head. Pectorals rounded about ^U length of head, 

 ventrals a Httle shorter reaching to vent or beyond. Pectorals reaching to about 

 fourth anal ray. Caudal strongly rounded. Fins to great extent black, especially vent- 

 rals, but also anal in all specimens quite black. Dorsal and caudal sooty with light 

 margin and tiie latter also with small light round spots (in spirit). Caudal peduncle 

 much deeper than long, its depth being contained about 3 times in length of head. 



This fish appears to be related to Nototlienia inarionensis GÜNTHER, but the 

 scales of the head are by far not so strongly developed in the former as in the 

 latter, at least if the South Georgia race of it is similar to the typical one from 

 Marion Island. The interorbital space of :V. inarionensis is much narrower and its 

 ventrals shorter not reaching the vent. Its head is narrower being about V3 of its 

 length and the snout is more pointed. The intensely black fins of the new species 

 seem also to present a very good characteristic. The race of N. inarionensis from 

 South Georgia has a much more slender caudal peduncle which is longer than deep 

 and with its depth less than a fourth of the length of head. The same fish has also 

 the caudal less strongly rounded than this new species. 



Nototlienia sima which has a similar number of fin rays and scales as N. karl- 

 andreœ differs from the same in having a less depressed and narrower head with
