NO. 2133. FISHES TAKEN BY "ALBATROSS," JS8S—TH0]\IPS0N. 453 



Scales not ctenoid on head; strongly so on flanks; interorbital 

 region densely and completely scaled from line of occiput to anterior 

 margin of eyes and tip of premaxillary process; opercle and sub- 

 opercle with large scales; cheeks to end of maxillary (not in advance) 

 covered entirely with small scales; a row posteriorly on interopercle ; 

 limbs of opercle, snout, and jaw naked; scales between dorsal and line 

 of occiput continuous with those on head, only slightly smaller than 

 those on body; area before and between ventrals scaled. 



Color usually dark; five broad irregular dark crossbands on body, 

 first above pectorals and opercle, second below second to sixth dorsal 

 rays, third broken above at lateral line to form two, last below last 

 dorsal rays; crossbands continued on to dorsal base to form five 

 blotches; first dorsal distally black; caudal submargined with black; 

 dorsals, anal and caudal, all narrowly edged with white, but other- 

 wise dusky or occasionally black; dorsal frequently with faded, 

 narrow oblique stripes evident in addition to other jDattern; a dif- 

 fuse bar on pectoral base, not sharply defined; on fully colored 

 specimens cheeks with two broad dark stripes, somewhat ill defined, 

 one from lower edge of eye running backward and slightly down- 

 ward until it fades at angle of preopercle; another from center of 

 eye back to black diffuse spot on upper part of opercle, as large as 

 pupil; ventrals and branchiostegal membranes sometimes strongly 

 pigmented, in none black; majority of specimens faded, nearly 

 without coloration. 



Notothenia longipes differs from N. tessellata as follows: Teeth 

 anteriorly in 4 or 5 series (not 2); velar flap much narrower; color- 

 ation entirely dift'erent; scales larger between occipital line and first 

 dorsal. It is difficult to understand Smitt's confusion of this species 

 with N. tessellata. 



It is probable that Vaillant's N. sguamifrons ^ is simply a large 

 specimen of N. longii)es, the more so as his identification of it with 

 that form was frankly provisional. 



The species recently named N. wiltoni by Regan ^ is apparently 

 described and figured from an adult specimen of N. longipes. Stein- 

 dachner's specimens were typical of smaller sizes. Our largest 

 specimen, 210 mm. in body length, 235 in total, corresponds in every 

 detail to those published of N. wiltoni (and is nearly the same size) 

 save for a very slightly broader interorbital space and the insertion 

 of the first dorsal over instead of slightly in advance of the opercular 

 flap as shown in Regan's plate. The smaller individuals below 

 180 mm. in length, differ from this specimen in the same details 

 upon 'which Regan relies to differentiate his TV. longipes from N. 

 wiltoni and correspond in every respect to the description of the 

 type by Steindachner.
