Hexagrammoides Gracianov, 289; orthotype H. nudigenis Gracianov, which is 

 probably Hexagrammos lagocephalus (Pallas) or perhaps H. superciliosus

 from a specimen from Bering Island. "Division of the dorsal fin not com- 

 plete; in the first dorsal about 20 rays." The name "nudigenis" indicates 

 scaleless cheeks, but H. stelleri, with the cheeks more fully naked, has more 

 than 20 dorsal spines.
