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



[Plate I. figs. 1-4.1 



Several of tlie doubly-armoured herrlugs of the genus 

 Di'plomt/stus* are muc\\ deepened in the abdominal region; 

 but none are so remarkable in thi.s respeet a.s 7X lon(jicostatu!i, 

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

 Upi)er Cretaceous of Alount Lebanon, which seems to have 

 hitherto escaped notice in collections among specimens of the 

 so-called Plafax minor. An accurate technical description of 

 the former has already been publi.shed by Professor Cope f, 

 but a good figure 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.
