REPORT ON THE AMPHIPODA. 587 



"[la the 'Zool. Coll. of II.M.S. Alcrt,^ p. 312, Mr. Miers refers to tliis genus and species as 

 Epliippiphora kroyeri (White), the original designation. Meanwhile the limits of the genus 

 and the characters of the species require complete revision]." Compare Note on Miers, 1884. 



To Tribe III. Hyperina, two families are assigned, emhracing between them five species. 



Fatn. I. Phronimidoe, contains Phronima iieo-zelaiiica, altered from Phroniina novas-zealandix, 

 Powell, and Tlmnisto aniarctira, Dana, for which see Note on Thomson, 1879. 



Fam. II. Platysoelidaj, receives the species Flatijscelus intermedius, Thomson, Oxi/cephaliis 

 edivardsii, Thomson, and Phreatoicus typicus, Chilton, with the following remarks upon the 

 last : — " The systematic position of this singular crustacean is doubtful. In general 

 appearance, I was inclined to place it among the Ampldpoda, but from the fact of the first 

 five pairs of pleopoda acting as branchial organs, and from the absence of any such organs 

 attached to the pereion, Mr. Chilton places it among the Isopoda. — G.M.T." The list 

 continues with " Suborder II. — Isopoda. Tribe I. Anisopoda. Fam. I. Tanaidae.," and 

 probably the aftinities of Plireatoicus will eventually prove to be rather with the Tanaida; 

 than with the Hyperina. I do not know what are the special reasons for classing it among 

 the Platyscelida;.

The various forms assumed by the second gnathopods of Orcliestia deshayesi, Audouin, are 

 described and figured. The lower antennfe in that species have calceoli, whereas in 

 " Orcliestia Kftorea Montagu," Blanc's observation that they are not to be found is con- 

 firmed. Orchestra brevidif/itata, Bate and Westwood, is shown to be in all probability only 

 a young, though somewhat abnormal, form of Orcliestia littorea. The list of species includes 

 three Orchestidoe, eleven Gammaridse, nine Corophiidie, two Hyperidoe, four " Laemodi- 

 podes," but it is recognised that several of the names given are probably synonyms.

For the group Bovallius gives the following diagnosis : — 



" Head free, not coalesced with the first pereional segment. 



" Eyes mostly large, often occupying the whole surface of the head. 



" First pair of anteunse without secondary flagellum. 



" MaxiUipeds coalesced into a kind of operculum, without palps. 



" Uropoda more or less laminar, forming natatory organs. 



" Telson undivided." 



The expression " more or less laminar " applied to the uropoda will only be accurate if understood 



to include some forms that are narrowly elongate and some that are prismatic. The group 



is divided into sixteen families, thus : — 

 Fam. 1. Tyronida 

 Gen. 1. Tyro, M.-Edw., 1840, with ten species, definitions being given of Tyro corniyera, 



M.-Edw., 1830, Tyro pacijjca, n. s., Tyro inarginata, Bovallius, 1885.
