I. — On two Deep-hodied Species of the Clupeoid Genua 

 Diplomystus. By A. Smith Woodward, F.L.S. 



[Plate I. figs. 1-4.] 



Several of tlie doubly-armoured herrings of the genus 

 Diplonij/stus * are much deepened in the abdominal region ; 

 but none are so remarkable in this respect as I), longicostatusj 

 from the Cretaceous of Brazil, and a smaller form from the 

 Upper Cretaceous of Mount Lebanon, which seems to have 

 hitherto escaped notice in collections among specimens of the 

 so-called Platax minor. An accurate technical description of 

 the former has already been published by Professor Cope f, 

 but a good tigure of a typical specimen is still wanted ; no 

 notice of the latter has hitherto appeared, and it will therefore 

 be interesting to point out its characters. Good examples 

 of both species are preserved in the British Museum, and 

 form the subject of the following notes.
