REPORT ON THE AMPHIPODA. 561 



Catal. by Spence Bate, except that to the gemric account is added the fact that the upper 

 antennsB are without accessory flagelluiu, and from the specific account is omitted the 

 statement that the peraeopods are subequah 



In the fourth subfani. Phoxinse, Sp. B., is given " Phoxus erythropldhalmus Catta. A. Ph. 

 Holbollii differt oculo perfecto in utroque latere. (Descriptio plenior nondum exstat.) 

 Habit.: Marseille, jMontredon (Catta)": to Pontocrates, Boeck, is attached the synonym 

 " Kroyei-ia Sp. B.," -which should be Kroyera. Acanthonofus, Owen, is retained in 

 preference to Epimeria, Costa, which, however, rightly supersedes Acanthonofus, preoccupied 

 long before Owen used it. Here also Carus places " Lilljehorgia Sp. B." and Guerinia, Hope. 



In the fifth subfam. Gammarinae (Dana), Cls., the habitat of " 3Isera Blanchardi Sp. B.," is 

 given as "Capo S. Viti, Sicilia (Milne-Edwards)," but the Brit. Mus. Catal., p. 190, gives 

 for this species "■Hah. Cape of Santo Viti, Sicily {M. Entile BJanchard)" and ascribes to 

 M. Blanchard "the description as well as the figure." To Meera eiythrophthalma, Heller, 

 " Eurtjstheut^ eri/tJirophthahnus Sp. B. " is assigned as a synonym, although the latter 

 species has the telson tubular, while Heller's sj)ecies has " telson in partes duas triangulares, 

 invicem imbricatas divisum." Ceradocus, A. Costa, is given as a synonym for Melita, 

 Leach, as well as for Mxra, Leach, Ceradocus orchestiipes, A. Costa, being assigned under 

 the latter as a synonym to ilenrc orchestiipes, Heller. Melita oxyura, Catta, is thus 

 described: — " Stipitis antennarum I. articulus 1. in extremitate spina forti armatus ; 

 segmenta caudalia margine postero-inferiore fortiter denticulate ; stUi caudales posteriores 

 graciles breves. Habit.: Marseille, Eatonneau, 10-13 org. prof. (Catta)." To Erotomedeia, 

 Kr., the synonyms " LejttochirKS Zadd., Ptilochirus Stimpe.," are assigned. Zaddach's 

 genus Leptocheirus has, however, been shown by Boeck to be distinct from Protomcdeia. 

 Some rearrangement therefore is necessary of the species assigned to this genus, viz. 1. 

 Protomedeia hirsutimcma, ^^. B. ?. "Habit.: Marseille (var. massiliensis) Catta," which 

 should be Leptocheirus liirsntimanus; " 2. Pr. pilosa Sp. B. {Leptochirtis pilosus Zadd.)," 

 which should be Leptocheirus pilosus, Zaddach ; "3. Pr. guttata Gr. ? ," "4. Pr. fasciata 

 A. Costa." The name Protomedeia fasciata, was used by Krijyer for the briefly 

 described type species of his genus. Stimpson's genus is not Ptilochirus, but 

 Ptilocheiru-s. 



In the sixth subfam. Lysianassiuw, Dana, for the eighth species, Lysianassa ciliata, Grube, 

 the synonym " .? L. Audouiuiana Sp. B." is suggested, but whereas in Lysianassa 

 audouiniana, " the central tail-piece is simple, squamiform, concave above, and rounded at 

 the apex," which agrees with the definition of Lysiaiiassa here given {telson simplex 

 squamiforme), Lysianassa ciliata, Grube, on the contrary, has the telson "usque ultra 

 medium fissum." Eyidia, A. Costa, has been identified by Boeck with Urotho'c, Dana, 

 1852. Ichnopus calceolatus. Heller, 1867, i.s identified bj' Boeck with his own Iclinopus 

 spinicornis, 1860. " Calliso7na Barthelemyi HoTpe," entered as "non descripta," has been 

 both described and figured. See Note on Costa, 1853. 



In the third tribe Hyperina, i\I.-Edw., in the first fam. Vibiliidoe (Dana) Cls., to " Vibilia 

 Jeangerardi Luc, are suggested as synonyms, " ? V. speciosa A. Costa, ? V. mediterranea 

 Cls." In the second fam. Hyperidffi (M.-Edw.), Sp. B., for Lestriyonus mediterraneus, A. 

 Costa, is substituted Hyperia mediterranea, V. Crs. In the fourth fam. Platyscelida', 

 Cls., and its first subfam. Typhidse, Cls., the name Eutypihis, Cls., is adopted with the 

 synonymy " Typhis Risso, Thyropus Dana c? , Dithyrus Dana et Pl(.dy.icelus Sp. B. 9 ," of 

 which, however, Dithyrus, Dana, has the claim of priority over Eidyphis. In the third 

 subfam. Lycteidse, Cls., to Lycsea rohusta, Cls., a synonym is suggested in " ? L. pulex, 

 Marion. In the fourth subfam. Oxycephalidie, Cls., Oxycejihalus, M.-Edw., has the 

 synonymy " Natalius A Costa, ? Omithorhamphus De Nat.," and the species Oxycephalus 

 similis, Claus, is accompanied by the synonym, "? Natalius candidissimus A. Costa." In
