The Fossil Fishes of the English Portlandian Formation are as yet almost unknown, and every small contribution to the subject is thus of interest. Ischyodus Townsendi, Microdon pagoda, the partially described Caturus angustus, an undetermined species of Thrissops, and an undescribed species of Mesodon, appear to be the only forms hitherto recorded; and to these may be added a large bony fish allied to Ditaxiodus, represented by jaws in the British Museum.
