the dorsal. In Lycodes brevipes the second bar is well behind the 

 front of the dorsal. In large individuals the color-markings disappear, 

 but specimens of any size may be known from Lycodes brevipes by 

 the longer ventrals, which are as long as, or longer than, the vertical 

 diameter of the eye, while in the latter species they are considerably 

 shorter than the eye, and by the more conspicuous mandibular folds- 

 With the original description (in which most of the above differences, 

 as well as others were noted) the small specimens agree, as do also the 

 large ones with exceptions which may be accounted for by size. 



In the specimen ten inches in length the head is contained 4.5 times 

 in the entire length; the depth 8.5. The pectoral is 1.8 in the head 

 (it is thus not materially different from Lycodes digitatus Gill and 

 Townsend). 



In one of the small specimens intermediate and less definite bars 

 occur between the bars across the body and fins, which do not reach to 

 the dorsal outline.

60. Microgadus proximus (Girard). 

 Several small specimens were collected on the beaches with the 

 seine, but it was not found in nearly such abundance as Theragra 

 Jiicensis, The following differences between this species and Mi- 

 crogadus tomcod of the Atlantic Coast may be published here from 

 notes made by Willis H. Rich, a student at Stanford University. In 

 Microgadus proximus the fins, especially the first dorsal, are more 

 falcate, while in Microgadus tomcod they are somewhat rounded. The 

 number of rays in the second anal varies from twenty to twenty-three, 

 while in Microgadus tom-cod they number from sixteen to nineteen. 

 The teeth of the outer row, especially along the side of the lower 

 jaw, are a little larger. The gill-rakers are larger and not so blunt; 

 their total number is from twenty-four to twenty-nine, while in 

 Microgadus tomcod they number from sixteen to twenty-two. The 

 color is lighter and not so much broken up into spots. The following 

 tables show the range of variation of gill-rakers and second anal rays.
