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



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

 Third nropods with equal rami. Telson entire. 



In this genus I place Calliope suhfrrranea, Chilton, and 

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

 Dr. Chilton regards as the adult male of his CaUiopius sub' 

 terraneus 1 leave at present unclassified. In quoting species 

 as typical of new genera I have given the earliest name 

 p-ublished, 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. 

 ]\Iandit)les with third joint of palp at least as long as second. 

 First maxillse with many setae on the inner plate. Second 

 maxillse with seta3 fringing the inner margin of the inner 

 plate, which is the narrower. Maxillipeds with inner plates 

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

 second joint. Second gnathopod stronger than first and more 

 stronglj^ subchelate. Fifth perseopods 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, Hasvvell, identical ; 

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

 (Edictrus novce-zealandice, Dana. 



Fam. Dexaminidae. 

 Paeadexamine, gen. nov. 



In general character like Dexamine^ Leach, but the lower 

 lip has the inner lobes well developed and X\\q mandibular 

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

 uniform on the light and left maxilla, and the maxillipeds 

 have a small distinct finger to the palp. 



The type species is Dexamine pacijlca, G. M. Thomson, 

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

 both liom New Zealand and from Jervis Bay, Australia. 



Here it may be mentioned that I find it expedient definitely 

 to establish the family Anamixidse, already suggested in 

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

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

 Metopoides, Delia Valle, and Proholoides^ Delia Valle ;
