3 After Smitt, measurements changed from hundredths of total length to hundredths of length without 

 caudal. 



1. NOTOTHENIA GILBERTI, new species. 



Plate 2, fig. 3. 



Described from the type and paratype taken at Laredo Bay, in the 

 Straits of Magellan, both 60 mm. in total length ; the type is author's 

 number 01-52, and 76853 of the United States National Museum. 

 Measurements of type and paratype in hundredths of body length 

 given in parentheses. 



Head (to tip of upper jaw) 3^ in body to base of caudal (0.29 to 

 0.28); depth 5J (0.19 to 0.21); eye 3i in head (0.08); snout 5 (0.06); 

 maxillary 3^ (0.07 to 0.08); mandible about 2h (0.12); width of 

 interorbital space 5 (0.06); length of pectoral H (0.24 to 0.27) 

 of ventral IJ (0.22) ; least depth of caudal peduncle 3f (0.08 to 0.085) 

 length of combined dorsal bases 1§ in body; of anal base 1-j^ or 2 

 D. VI 32; A. 31 (30); pectoral rays 22; scales with pores in upper 

 lateral line 45; in lower line 6; scales in lateral series 70 (73); in 

 transverse from origin of anal obliquely forward and upward 6 + 22 

 (26 to 28); gill rakers 9 + 12. 



Width of head equal to its depth at the opercles, squarish in 

 section, the sides somewhat parallel; snout extremely short, project- 

 ing but little beyond the anterior edge of the eye; profile of head 

 descending along anterior border of eyes as far as nostrils, and 

 then slightly forward to meet the premaxillaries; lower jaw longer 

 than upper, mandible very long in proportion to maxillary; inter- 

 opercle in large part covered; upper limb of preopercle vertical; 

 breadth of velar flap measured from tip of lower jaw contained three 

 times in eye; teeth small, in three rows anteriorly above and two 

 below, a single row laterally in both jaws, rows subequal; gill rakers 

 short.
