I. HISTORICAL 1SOTES 01N THE OXYCEPHALIDS, 



The Oxycephalids seem to have been comparatively late attended 

 to by the zoologists, the first who described such an animal was H. 

 MILNE EDWARDS, 1, the great reformer of the carcinological system, giving 

 in 1830 the diagnosis of the genus Oxycephalus. He placed the 

 new genus among the Hyperines anormales)), but said Ces amphipodes 

 s'eloigneut de la plupart des Hyperines par la forme grele et allonge"e, 

 par leur tete aplatie et lanceolee, etc.)) The species he named Oxy- 

 cephalus plscatoris. 



Two years later ANASTASIO Cocco, 2 and 2 a, established the new ge- 

 nus Orio, which partly is synonymous with Oxycephalus, his species Orio 

 Ornithoramphus, however, is very difficult to identify, owing to the incom- 

 plete diagnosis ; a facsimile of his drawing is given by STEBBING 1. c. p. 

 145 ; as far as I know it is the first drawing of an Oxycephalid, met with 

 in the literature. NICOLO PRESTANDREA, 3, described in 1833 a new species 

 of the just mentioned genus, Orio oxyahingus; it is very unclear where 

 this species might be placed, in the systematical arrangement below it 

 is omitted as being deficiently described; STEBBING 1. c. p. 152 assumes 

 that Oxyahingus must be a misprint for Oxyrhingus, and this probably 

 a malformation for Oxyrhynchus. In 1836 F. E. GUERIN, 4, instituted the
