11. NOTOTHENIA BREVICAUDA Lbnnberg. 



Notothenia brevicauda Lonnberg, Swedish South Polar Expedition, Wissensch. 

 Ergeb. Schwed. Siidpolar Exp., vol. 5, 1905, Lief. 6, p. 6, Ushuaia, 10 meters 

 (not N. brevicauda Regan). 



The very short and deep caudal peduncle of this species appears 

 entirely distinctive; in other regards it seems to be related to Noto- 

 thenia longicauda, new species, differing slightly in body depth and 

 height of fins. No specimens are at hand which answer Lonnberg's 

 description. 



''D. V, 35; A. 32; Squ. 66. 



"Head moderately compressed, extensively scaly all over except 

 on snout to above nostrils and preorbital. Body rather strongly com- 

 pressed. Depth of body four and four-fifth times in total length 

 without caudal. Length of head three and one-half times in total 

 length without caudal. Diameter of eye four times in length of head. 

 Interorbital width about seven times in length of head. Snout a 

 httle longer than diameter of eye. Upper lateral fine with 45 to 46 

 tubular scales, lower lateral fine with only 5 to 6 tubular scales, but 

 in front of them may be counted a great number of pitted scales, on 

 one side 20. First dorsal basally somewhat connected with second. 

 Longest ray of former shorter than longest ray of latter, which is 

 equal to half the length of the head. Longest anal rays about one- 

 third length of head. Pectoral rounded about two-thirds length of 

 head, reacliing beyond origin of anal. Ventral about five-sevenths 

 length of head, reaching beyond origin of anal. Caudal very strongly 

 rounded. Caudal peduncle much deeper than long, so short that 

 anal as well as second dorsal when laid back reach beyond the same, 

 its depth not even contained twice in length of head. Anal and 

 ventral fins as well as gill-membrane dusky." (Lonnberg.)
