332 THE VOYAGE OF H.M.S. CHALLENGEE. 



1862. Bate, C. Spence. 



Cataloo-ue of the specimens of Amphipodous Crustacea in the Collection of the 

 British Museum. London. 18G2. iv and 399 pages. Plates I.-LVIII. with Plate 

 la. Plate XXI. has its lower half devoted to Plate XlVa. 



This ambitious work, beyond the promise of its title, aims at bringing together, in systematic 

 arrangement, all the Amphipoda then laiown to science. The preface explains that the 

 arrangement of the species follows the classification proposed in the British Association 

 Eeport for 1855, and adopted in the " British Sessile-eyed Crustacea " then in course of 

 publication, but that observation during the progress of the Catalogue had " suggested a 

 more natural arrangement by the absorption of the Orchestida3 as a subfamily into the 

 Gammaridaj, establishing the Phoxides as a distinct family, and placing them between 

 Corophiidffi and Hyperidse." 

 The new species described and figured are, in Fam. 1. OncHESTiDJi : — Talorchestia ? Africana, 

 with the remark that " it may be the female of the OrchesHa that Krauss supposed to be 

 O. Bottle ; " " Orchedia Auclilcmdix," Hah. Auckland, as to which ilr. G. M. Thomson 

 writes to me from New Zealand, expressing the opinion that Auckland Islands must be 

 intended. Orcliestia Fuegensis ; " Orchestia Novx-Zealandiai," -which, alojxg with Orchestia 

 tenuis, Dana, G. M. Thomson unites under the common name Orcliestia sijlvicola, Dana ; 

 " Orchestia Telluris," of which G. M. Thomson remarks that it "is by no means a terrestrial 

 species. It lives in burrows in the sand just above tide-marks ; " Orchestia mecjalophthalma 

 (Orchestia megalophthalmus. Leach MS., and White's Cat. Crust. B. M.) ; Orchestia triyono- 

 cJieiriis (Leach MS. B. M.) ; " Allorchestes Piedmoniensis"; " Allvrchestes Enickerhockeri," 

 a species which W. Faxon thinks may be synonymous with Amphithoe aztecus, Saussure, 

 ■ 1858, and the later Hyalella dentata, S. I. Smith, as Professor Smith had' himself 

 suggested, in which case the name would be Hyalella adeca ; Allorchestes carinatus ; 

 " AUorchestes Sayi"; Allorchestes inicrojMhahmts {Gamm&mii microphthalmus, 3IS. Brit. 

 Mus.) ; ^^Allorchestes Inca," said to be perhaps a sex-form of Allorchestes hirtipalma, Dana; 

 (for reference of species of Allorchestes to the genera Hyalc and Hyalella, see 'Note on 

 Eathke, 1837). 

 In Fam. 2. GAMMAKiDiE. Subfam. 1. Stegocbphalides : — Montagua longinmna, perhaps only a 

 variety of Stenothoe monoculoides ; ^^ Montagua (r^jecHiu'," which Spence Bate says bears a 

 strong resemblance to Stenothoe vcUidus, Dana. 

 In Subfam. 2. Lysianassides : — Anonyx longicornis, subsequently transferred by its author to 

 the genus Lepidepecreum ; Anonyx ohesiis, subsequently made the type of the genus Acido- 

 stoma, Lilljeborg; Anony.v ampidloides, Stimpson, MS.; Anonyx imnctatus, StLmpson, ]MS.; 

 Anonyx anmilatus, Stimpson, MS.; Anonyx longipes, which with Bate's " Anonyx ampulla, 

 Kroyer," Boeck renames Tryphosa longipes, as respectively female and male of one species ; 

 Phlias rissoayius. 

 In Subfam. 3. Ampeliscades : — Ampielisca ingens (Pseudophthalmus ingens, Stijnpson, MS.): 



" Ampelisca Japonica," (Ampelisca Japonica, Stimpson, MS.). 

 In Subfam 4. Phoxides : — ■ 



Grayia, new genus, is thus defined : — " Cephalon produced, hood-shaped. Eyes two. Superior 



antennte not appendiculate. Gnathopoda subchelato. Pereiopoda subequal, and terminating 



in a sharp-pointed curved dactylos. Posterior pleopoda biramous. Telson squamif onn, entire ! 



" Tliis genus differs from CEdicerus of KrSyer in having two eyes, and in the fifth pair of 



pereiopoda not being longer than the preceding." 

 To this genus two species are assigned, Grayia indjricata, n. s., which, in the opinion of A. M. 

 Norman and myself, is the young of Amathilla sabini, and Grayia piugettensis, Dana, as to
