Described from seven specimens taken at Albatross station 2771, off 

 Cape Redondo, Patagonia; one from Gregory Bay; and one from 

 Island Harbor, Patagonia, the last taken as tbe type Cat. No. 76856, 

 U.S.N.M. The type (78 mm. in body length) is the only specimen 

 in a good state of preservation; the others are shrunken and brittle 

 from strong alcohol. The longest specimen is 110 mm. in total 

 length. 



Head 3f (0.28 to 0.30) in length to base of caudal; depth of body 

 5H0-19to0.21); eye 4 in head (0.07 to 0.08); snout 3f (0.07 to 0.08); 

 length of maxillary 3 (0.09 to 0.10); of mandible 2| (0.10 to 0.12); 

 width of interorbital space 6\ (0.035 to 0.045); length of pectoral 

 If (0.18 to 0.20); of ventral IJ (0.18 to 0.20); depth of caudal 

 peduncle 3i (0.07 to 0.08); D. V, 36 (35); A. 33 (32 or 33); pectoral 

 rays 24; scales with pores in upper lateral line 48 (47 to 50); in 

 lower 5 (0 to 7); in lateral series 65 (65 to 75); in transverse series 

 from insertion of anal obliquely forward and upward 4 + 18 (21 to 

 26); gill rakers 9 + 16 (30 to 34). 



Width of head equal to its depth; maxillary ending under anterior 

 third of eye; interorbital narrow; upper surface of eye exposed and 

 colored; jaws nearly equal; teeth in four rows anteriorly in both 

 jaws, outer row only shghtly enlarged; width of velar fold measured 

 from tip of lower jaw shghtly more than haK diameter of eye; least 

 depth of preorbital 3^ in eye. 



Insertion of dorsal over pectoral base; distance from last dorsal 

 rays to end of muscular part of tail equal to depth of caudal peduncle ; 

 last dorsal ray over next to last anal ray; height of first dorsal equal 

 to diameter of eye; of second 2f in head, but shghtly lower pos- 

 teriorly; anal height nearly equal thi'oughout, equal to that of first 

 dorsal; ventrals extending to anus; pectorals rounded; caudal 

 rounded. 



Upper lateral line approaching to within three or fom- scales of end 

 of muscular part of tail; lower very short, or absent, overlapped two 

 scales by upper lateral lino. 



Scales present on interorbital space to between anterior border of 

 eyes, but absent on line of occiput over occipital tube of lateral line 

 organs, a small bare space of greater or less extent also present before 

 it in median Ime; scales on cheeks and opercles as in Notothenia 

 longipes, ahsent on snout, jaws, limbs of preopercle, and interopercle; 

 present on subopercle. 



Color very dark, without definite pattern on body; dorsal and anal 

 very dark, latter nearly black; ventrals dusky; pectorals and caudal 

 clear; branchiostogal membrane very dark, margin clear. 



There are none of the characteristic markings of Notothenia longipes 

 visible, and the anatomical characters which distinguish it from that
