210 Rev. T. R. R. Stebbing's Revision of Amphipoda. 



fifth joint of second pair rather long. Fifth perseopods normal. 

 Third uropods witli equal rami. Telson entire. 



In this genus I place Calliope suhterranea^ Chilton, and 

 Pheriisa ccerulea, G. M. Thomson ; but the form which 

 Dr. Chilton regards as the adult male of his Calliopius sub- 

 terroneus I leave at present unclassified. In quoting species 

 as typical of new genera I have given the earliest name 

 published, it not being desirable to burden the present paper 

 with synonymy. 



Paeacalliope, gen. nov. 



Body without dorsal dentation. First antennae the shorter, 

 without accessory flagellum. Lower lip with inner lobes. 

 ]\Iandi!-les with third joint of palp at least as long as second. 

 First maxil!a3 with many setre on the inner plate. Second 

 maxilla? with setw fringing the inner margin of the inner 

 plate, which is the narrower. Maxiliipeds with inner plates 

 rather broad, outer plates reaching the apex of the palp's 

 second joint. Second gnathopod stronger than first and more 

 strongly subchelate. Fifth perfeopods much the longest, 

 with the finger long, straight, spinose. Uropods with 

 slender rami, those of the third pair equal, not longer than 

 the peduncle. Telson short, entire. 



The type species is Calliope Jluviatilis, G. M. Thomson, 

 with which I consider Pherusa australis, Haswell, identical ; 

 and I also think it quite possible that both are synonyms of 

 (Edictrus nova-zealandice, Dana. 



Fam. DexaminidaB. 

 Paeadexamine, gen. nov. 



In general character like Dexamine, Leach, but the lower 

 lip has the inner lobes well developed and the mandibular 

 processes upturned ; the first maxillas have a one-jointed palp 

 uniform on the light and left maxilla, and the maxiliipeds 

 have a small distinct finger to the palp. 



The type species is Dexamine pacijica, G. M. Tiiomson, 

 which, through the kindness of my friends, I have received 

 both from Kew Zealand and from Jervis Bay, Australia. 



Here it may be mentioned that I find it expedient definitely 

 to cstablisli the family Anamixids, already suggested in 

 1897, and to institute various new families, namely: — Mcto- 

 pidai, to include the genera Metopa, Boeck, Metopella, Sars, 

 Metopoides, D^ 11a Valle, and Proboloidea^ Delia Valle ;
