Family METOPIDAE 



Stebbing, 1906, p. 171. 



Excluding the genus Thaiimatelson , the number of Antarctic and sub-Antarctic species 

 of this family is now eighteen, including the two new species described below. A further 

 increase is no doubt to be anticipated, as the family is represented in northern waters 

 by a large number of species. Up to the present no representative of the typical genus 

 Metopa has been found in southern waters. See also Schellenberg, 1931.
