214 THE VOYAGE OF H.M.S. CHALLENGER. 



To receive this genus Dana instituted the family Dulichiidae, in 1849. Stegocej}halus inflatws, 

 Kr0yer, is next described in detail. This is now known as Stegoeephalus ampulla, Phipps, 

 1774. 



Pontoporeia femorata, Kr0yer, is here next described in detail, but without any reference to the 

 curious dorsal process which is represented in the Voy. en Scand. pi. 23, figs. 2a, 2y., on the 

 observation of which Bruzelius established a new species, Pontojjoreia furcir/era, which, 

 according to G. 0. Sars, is not distinct from Pontopweia femorata. 



Descriptions are next given of Leucotlioe glaeialis, Kr0yer, Tab. vi. fig. 2, a-f, Leucothoe rli/pieata, 

 Kr0yer, Tab. vi. fig. 3, a-g, " Phoxus Holholli Ivr." and Phoxus jjlumosus, Kr., now known 

 respectively as Metopa glaeialis, Metopa dypeata, Phoxus holholli and llarpinia p)lunwsa. 

 Kr0yer himself was inclined to regard the two latter as generically distinct. Of both species 

 he notes that he has never found the maxillipeds united to the head, but always to the first 

 peraeon-segment. 



Pages 578-637 are devoted to the genus Anonyx. Kr0yer first discusses and describes at great 

 length what he calls " Anonyx Ampulla, Phipps," combining with it " Cancer nugax 

 Phipps]?," his own "Anonyx Lagena (Hunnen)," Anonyx appendiculosus (Hannen), and 

 other synonyms. The species which he here describes, which he figures in the Voy. en 

 Scand., pi. 13, fig. 2, a-z, and which does in fact include the species of Anonyx just 

 mentioned, is now known as Anonyx nugax, Phipps, while the Cancer ampulla of Phipps, 

 figured here pi. vii. fig. 3, a-g, and in the Voy. en Scand., pi. 20, fig. 2, a-t., as Stego- 

 eephalus inflatu^, Kr., is now known as Stegoeephalus ampulla, Phipps. 



A fuU description is next given of " Aiwnyx Vahlii Kr." which Milne-Edwards had transferred 

 to Lysianassa, and which Boeck calls Socarnes vahli. 



Anonyx gulosus, n. s., is described, with a note that " Fabricius's Oaiscus Cicada seems in many, 

 if not in all, respects to come very near to it, and is obviously in any case an Anonyx." 



Anonyx litoralis, n. s., is next described. This was made by Boeck type of a new genus 

 Onesinvus, which he thinks possibly a synonym of Milne-Edwards' Alihrotus, to which 

 Spence Bate had previously referred the Anonyx litoralis of Kr0yer. 



A species, to the young and sexes of which Captain Holb0ll had given three separate manuscript 

 names, velatus, omattis, and brevipes, is next described as Anonyx plautus, n. s. This 

 also is placed by Boeck in his genus Onesimus. Figures of the various species above 

 mentioned are given in the Voy. en Scand.

No Amphipoda are mentioned in this report, so far as I can perceive. It was perhaps included 

 in Boeck's list under some misapprehension.
