Protosyngnathus sumat)'ensis,n. gen. and sp., is characterized by having 

 ossified vertebrae only in the hinder part of the column, no ventral fins, 

 and more rows of dermal plates than in Pseudosyngnathus, while there is 

 an anal fin opposite the dorsal. Sardinioides amblyostoma, n. gen. and 

 sp., is allied to the herrings; the head is badly preserved, and the scales 

 are not seen. Brachyspondylas saropterix, n. gen. and sp., has not 

 the head preserved, but seems akin to the Westphalian Cretaceous genus 

 with narrow vertebrae. B. imlicus, n. sp., is placed under the same 

 genus. [See Gunther, p. 257.] E. B. T.
