good drawing, which clearly shows that the specimen described by these 

 naturalists is identical with the type species of H. MILNE EDWARDS. 



In 1849 HERCULE NICOLET, 10, mentioned Oxycephalus oceanicus from 

 the seas of Chile, and H. LUCAS, 11, the genus Oxycephalus among the 

 Hype'rines anormales)). 



In 1850 GUISEPPE NATALE, 12, promoted the specific name Ornitho- 

 ramphus, given by Cooco, see above p. 2, to a generic name, and cal- 

 led the species 0. Coccoi. He described this species at length but with- 

 out good characteristics; if it is identical with Cocco's species or not, 

 is very difficult to settle. STEBBING 1. c. p. 241 suggests, that it possib- 

 ly may have some relation to Oxycephalus typhoides, GLAUS; according to my 

 opinion it is rather near to Oxycephalus latiros tr is, GLAUS, ho wbeit, the 

 genus is most likely a synonym for Oxycephalus, H. MILNE EDWARDS. 

 NATALE was doubtful if Ornithoramphus might be rather an Isopod, allied to 

 Sphceromidce, than an Amphipod. In the same year the same author, 13, pu- 

 blished in an other paper one more new generic name, Erpetoramphus, also 

 probably synonymous with Oxycephalus. Owing to the vague description 

 it is impossible to identify the species which he named E. Costce. 



In 1851 H. LUCAS, 14, mentioned and figured Oxycephalus oceanicus, 

 GUERIN, not adding any new characteristics. 



In the same year Fr. GUGL. HOPE, 15, issued a catalogue of the 

 crustaceans of the Mediterranean, he enumerates without any charcteri- 

 stics, under Amphipoda, the following, above mentioned Oxycephalids viz; 

 Orio oxyrhynchus, PRESTANDREA, 0. ornithoramphus, Cocco, Ornithoramjjhus 

 Coccoi, NATALE, and Erpetoramphus Costce, NATALE.
