Placodus andriani, Miinster l . 

 Syn. Placodus bomhidens, Owen 2 . 



Smaller than the type species, with the palatine teeth relatively 

 shorter antero-posteriorly and the parietal foramen very large. 



The undermentioned mandibular ramus described as P. bombidens 

 agrees in size with the cranium of the present species, and exhibits 

 no characters by which it can be distinguished therefrom.
