Changes in growth: Measurements of different sized L. diapterus beringi 

 indicate that certain characteristics may vary with age in different ways. 

 Distribution of sizes of those examples measured are:

In the following table (see beiow)shows the direction of changes with 

 group (in percentage of TL) . 



It indicates that: 



1. Positively correlated age changes (with length) are: depth of body 

 and length of upper jaw. 



2 . Negatively correlated changes are: length of head, eye, pectoral 

 and ventral length .

Our subspecies along with other deep water representatives (as Nematonurus 

 pefctoralis) was found at Commander Ids . at depths of 200 meters . In the stomachs 

 were polychaeta . 



This subspecies is close to L. diapterus diapterus Gilbert from Oregon but 

 differs in a less deeply cut pectoral and in fewer pectoral rays (18*^19 versus 20- 

 21 in L. diapterus Gilbert), fewer bars on body (5-6) and with well developed dark 

 nasal tubes. (Gilbert states "nostrils with a short inconspicuous tube", I.e., 

 1891, p. 564) and in some body proportions. Our form is close to Lycodes
