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



from the female only), what he calls " gefieJerte Kieme," the branchise not simple, but 

 carrying symmetrically arranged supplementary vesicles, an arrangement now known to 

 exist in several species, and already described by Costa in Ichnopus. He also draws dis- 

 criminating characters from the mouth-organs of the three species longicornis, (probably the 

 ? so-called), spinicornis and ciliata. 



Grube makes LeptocJieirus, Zaddach, and Ptilocheirus, Stimpson, synonyms of Protomedeia, 

 Kr0yer, in agreement with Spence Bate and other writers, but Boeck places Leptocheiru$, 

 with Ptilocheirus for a synonym, in his subfamily Leptocheirin<e, and Protomedeia in the 

 subfamily Microdeutopinge, the differences being in the maxillipeds, the side-plates, the 

 sesond gnathopods, and the last uropods. In the Leptocheirinae, moreover, it is noted that 

 ' the first joint of the mandibular palp is elongate. Grube describes ■'■Protomedeia 



hirsutimana, Sp. Bate? Taf. x. fig. 2," but in the description of " Taf. x. fig. 2," he calls it 

 " Protomedeia pilosa (Zadd.)," having apparently convinced himself of the identity of his 

 own specimen with Zaddach's species. His new species, Protomedeia yuttata, Taf. x. fig. 3. 

 as well as the old one, must evidently be placed in the genus Leptocheirus. 



He figures his species Crangonyx recMrvus, Taf. x. fig. 1, and describes it anew. 



Being unacquainted with Garmnarus marinus, Leach, Grube refers a species, which he had 

 previously called Gammartis olivii, M.-Edw., to Gammarus pwcilums, Eathke. He describes 

 Gamviarus gracilis, Eathke, recognising that it may be only a variety of Gammarus 

 pcecilurus. All these Gammari are by Boeck accepted under the name Gammarus marinus, 

 Leach. Grube concludes tlus paper with a description of Gammarus locusta, Linn.

Orehestia montagui, Audouin, is given as a distinct species from Oreltestia littorea, Leach, but 

 Orchestia constricta, Costa, is made synonymous with Orehestia montagui. The new species 

 described and figured a.v& Nicea pilumicornis ; Nicea fasciculata ; " Nicea DuccMchi" Nicea 

 nudicomis ; Nicea macronyx, which will be Hyale prevostii, if Catta is right in identifying 

 it v!\i\\ Ampihithoe prevostii, M.-Edw.; Nicea camptonyx ; "Nicea Schmidtii ;" Nicea ritdis ; 

 Nicea ci-assipes ; Proholium megacheles, which being without mandibular palj) must be 

 transferred to Dana's genus Stenothoe, and, for the species, is identified by Catta, 1876, with 

 Costa's ProhoJium poJi/j^rion ; Lysianassa pilicornis ; Ichnopus affinis ; Irhnupus ccdceolatus, 

 identified by Boeck with his own Ichnopus spinicornis, 1860; '^ Anomjx Schmardse," in 

 Boeck's opinion, perhaps, together with the next species, belonging to his genus Amliasia ; 

 Anonyx Jilicornis ; " Anonyx Nardonis" (at p. 59 by a misprint assigned to Kr0yer), said 

 to differ little from Anonyx nanus, and by Boeck referred to his genus Tryphosa; Iphimcdia 

 carinuta, not figured, and not in my opinion specifically distinct from Iphimedia obesa, 

 Eathke, which includes two other synonyms or varieties, Iphimedia ehJanx, Sp. Bate, and 

 Iphimcdia multispinis, Grube ; Eusirus hidens, already described by Boeck as Eusirus 

 longipes; " Melita Coroninii;" Mara integrimana; "Mara Donatoi," which, like 

 Mxra grossimanus, Montagu, and Mara Loveni, BruzeUus, has the finger of the second 

 gnathopods fringed with hairs on the outer margin ; Amphithoe hicuspis, a name preoccupied 

 by Kroyer, and the species identical with Snnamphitho'd confurmata, Sp. Bate ; from 

 Sunamphithoe hamulus Heller himself observes that it is distinguished only by the greater
