EEPORT ON THE AMPHIPODA. 443 



brevi instructum, oouli rotundati. Dorsum carinatum, omnia segmenta thoracis et quatnor 

 segmenta postabdominis anteriora carina in margine posteriore in dentes acutos desinenti. 

 Angulus inferior posticus lateralis segmenti postabdominis l"', 2'" et 3" in dentem 

 acutum productus. Pedes saltatorii ultimi paris pnelongati, ramis laminiformibus, in 

 margine spinulosis. Appendix caudalis obovata, usque ad dimidiam partem styli pedum 

 saltatoriorum ultimi paris porrecta, in margine posteriore sinuata." It is further remarked 

 that this new genus stands between Ainathilla and Gammararrmfhus, that it has in common 

 with Amathilla the compressed carinate body, the small similarly shaped subcheUform first 

 and second gnathopods, and the simple emarginate telson, while it Is distinguished from it 

 by the elongated upper antennro, the presence of an accessory flagellum, the slender form of 

 the first (femoral) joints of the three last peraeopods, the elongate third uropods and the 

 shortened third joint of the mandibular palp. With Gammaracanfhus it agrees in the 

 form of the antennae, in the shape of the first joints of the three last peraeopods, as well as 

 in the elongated last urojjods. It is easily distinguished from it by the short rostrum, the 

 feeble gnathopods, the form of the telson, the structure of the mandibles and mandibular 

 palp, the strongly outward curved lateral edges of the perseon-segments, and the small 

 inferiorly toothed side-plates. 



It is rather doubtful whether this genus belongs to the Gammarinse, among which Heller in the 

 above remarks seems inclined to place it. It seems to approach the subfamily Epimerinse, 

 Boeck, notwithstanding the minute secondary aj)pendage to the upper antenna, in the 

 presence of which it iir fact resembles AmafliiUa as well as Gammaracanthus. An additional 

 species, Ainatkillojjsis affinis, from Franz- Josef Land, has been contributed to the genus by 

 Mr. E. J. Miers. 



Figures and descriptions are given of " Anoni/x lagena Kroyer," " Aristias tumidus Kroyer," 

 Onisimiis littoralis Kroyer," with some notes on " Aranthostcpheia Malingreni Goiis," and 

 some other known species. To Krfiyer's Anonyx lage^ia, " Cancer ampulla Phipps " is 

 given as a synonym, obviously only by a slij) for Cancer nugax.

Of this paper P. Mayer, Caprelliden, p. 70, gives the following account, " Caprella xpinosa. 

 Lockington, from Hakodadi Bay, is distinguished by the considerable length of the male 

 (body exceeding 1 inch, anterior antennas 1 inch long). From the description, however, 

 nothing further can be derived, than that the author does not know the genera with more 

 than five pairs of legs, and also that he takes no account of the mandibular-palji, etc. The 

 species must therefore be considered indeterminate."
