£1.00
Further specimens of the Downtonian Ostracoderm Corvaspis kingi Woodward are described, and the genus is shown to belong to the family Psammosteidae. The variation of ornamentation seen in Corvaspis is used to demonstrate the relationship between the three main types of growth of dermal plates known in the Heterostraci.
