Ampliipodous Crustaceans. On the genera Hyale and Anonyx and a new species 

 of Probolium. The Annals and Magazine of Natural Histoiy. May, 1876. Ser. 4. 

 Vol. XVII. London, 1876. pp. 337-346. Pk 18. 19. 



The species named in the Brit. Sess. Crust., " AUoirhestes N/lgoiiii," Eatlike, and " Nirea Luh- 

 hucldana," Sp. Bate, are here called respectively " Hyale Nilsonii," and " Hyale Luhbocldana," 

 Boeck's view being accepted that AUoirhestes and Nicea are both synonyms of the earlier 

 Hyale of Rathke. Boeck's opinion that the two species in question are also identical is 

 rejected. I am at present inclined to believe that HyaJc hihhorliiana is a synonym of 

 Hyale pontica, Rathke. Under the heading " Anonyx serratus, Boeck," the suggestion is 

 made that Orchomene jnnguis, Boeck, Orcliomene serratus, Boeck, and Orchomene minutus, 

 Kr0yer, are but one species, which might be retained in the genus Anonyx. It is proposed 

 that " Anonyx Edirardsi" and Anonyx minutus of the Brit. Sess. Crust., i. pp. 94, 108, 

 should fall to the same name. G. 0. Sars decides, in 1882, that Lysiaiiassa longicornis, 

 Sp. Bate, and " Anonyx Edwardsi," Sp. Bate (non Kr0yer), are respectively the male and 

 female of one species, which he names " Orchomene Batei;" but the first gnathopods of 

 the species which Spence Bate accepts as Lysianassn longicornis, Lucas, will not admit of 

 this identification. The male specimen which I have described in this paper is no doubt 

 " Orchomene Batei^'' Sars. 



" ProJiolium Spence-Batei," n. sp., is described and figured, but as nothing is said about the 

 mandibles, and the specimen itself has perished, the true position of this species must remain 

 indefinite. It may possibly belong to Amphilochus, rather than either to Sien.Qtho'e or 

 Metopa, to one or other of which species of Probolium are generally synonymous. 



Some notes on Urothoe are given.

AmpMloelius concinna is described as a new species, but as subsequently explained in the Annals 

 for November 1878, it is probably identical with Amphiloclnis mamidens, Sp. Bate, though 

 differing to some extent from that author's account of his species. Meinert records it from 

 Storebelt. Danaia dubia, Sp. Bate, is figured and described. Callimerus acudiyitata is 

 described and figured as a new genus and species, but this is subsequently cancelled in the 

 Annals for November 1878, as being a synonym for Amphilochus mamidens. Exunguia 

 stiliptes, Norman, 1868, and Cratippus tenuipes, Sp. Bate, 1862, are compared, the conclusion 

 drawn being that the genera are the same. No doubt the species are also identical. 

 Colomastix pusilla, a new genus and species described by Grube Ln 1861, bears a strong 

 resemblance, and in regard to the generic name, Colomastix supersedes both Cratippus and 

 Exunguia.
