8 Carl Bovallius, The Oxycephalids. 



In 1879 Claus, 27, made a revision of the known Platyscelids, 

 and quoted among tLem the following genera and species as belonging 

 to the family Oxycephalidae. Oxycephalus piscator^ H. Milne Edwards, 

 as observed above, p. 6, identical with 0. Clausi, C. Bovallius, 0. m»i7is, 

 in my opinion probably a synonym for 0. piscator, H. Milne Edwards, 

 0. latirostris, n. sp., 0. tenuirostris, Claus, quoted as Leptocotis 

 tenuirostris below, 0. porcellns, n. sp., = Streetsia porcellus, 0. 

 longiceps n. sp. = Streetsia longiceps, 0. typhoides n. sp. = Steb- 

 bingella typhoides. He adhered to his former statement that Rhah- 

 dosorna Whitei, Spence Bate, was synonymous with Rh. armatum^ H. Milne 

 Edwards. He transferred the genus Simorhynchus to the family y)Lycœidœ'». 



In 1880 Claus, 28, placed Oxycephalinœ as the fifth subfamily of 

 the fourth Hyperiidean family Platyscelidœ.^ quoting the same genera as 

 in the just cited work. 



In the same year Otmar Nebeski, 29, added important facts to 

 our knowledge of the anatomy of the Amphipods; he did not investigate 

 any one of the Oxycephalids but many of his statements throw light 

 upon analogue peculiarities in this family. Just the same ought to be 

 said about Yves Belage, 30, and his admirable treatise on the organs 

 of circulation of the marine Edriophthalmata. 



In 1884 Geo. M. Thomson, 31, described a new species of Oxy- 

 cephalus, 0. Edwardsii^ which, however, probably is sjiionymous with 

 0. piscator, H. Milne Edwards, see below under this species.
