names as specific, this would seem to le one of the rare cases in which original names 

 might justifiably be changed on account of their inappropriateness. The difficulty, however, 

 will not arise, if, as already suggested, the names may be considered synonyms of HyaleUa 

 andina, Philippi, 1860. Gammarus limnxus, Smith, pi. ii. figs. 13-14, from "Lake near 

 Long's Peak ; elevation, 9000 feet," is described, and Gammarus rohustvs, n. s., pi. ii. figs. 

 7-12, from Wahsatch Mountains, Utah.

Tlic Crustaceans of the Caves of Kentuchj and Indiana. From the American 

 Journal of Science and Arts, Vol. IX., June, 1875. 



Sfijfjohromus vitreus. Cope, from Mammotli Cave, is said to be really a Crangonyx, which 

 should stand as Crangonyx vitretis (Cope). Crangomjx vitreus, Packard, from Indiana, is 

 very different from Cope's species, but closely allied to Crangonyx gracilis, from Michigan, 

 Lake Superior, etc., differing principally in the structure of the eyes. Since Packard's 

 species in any case must yield its specific name, one is led by Professor Smith's account to 

 regard it as a synonym of Crangonyx gracilis.

On the genus Bathyporeia. The Annals and Magazine of Natural History for 

 January 1875. Ser. 4. Vol. 15. PI. III. pp. 74-78. 



Bathyporeia pilosa, Lindstrom, is figured and described, with an argument to show that 

 Bathyporeia pelagica, Sp. Bate, is the adult male, a.nd" Bathyporeia Eobertsoni," Sp. Bate, a 

 younger form of the male, of the same species of which Bathyporeia pilosa is the female. 

 G. O. Sars, has expressed the opinion that Bathyporeia rohertsoni is a distinct species. H. 

 Blanc accepts my view.

On some new exotic Sessile-eyed Crustaceans. The Annals and Magazine of 

 Natural History for March 1875. Ser. 4. Vol. 15. PI. XV. A. pp. 1-4. 



In this paper a new sjjecies is described under the name Dejximine antarctica. This in 

 November 1878 I transferred to Atylus on the ground of its likeness to Atyltis gibbosus, 

 Sp. Bate, and of its residing, like that species, in a sjionge. Atylus gibbosus, however, 

 having no palp to the mandibles, belongs not to the Atylinw, but to the Dexaminae, and is 

 made by Boeck the type of a new genus Tritxta, which name he derives from the Greek 

 TpLTaia, without explaining why he introduces an additional letter into the Latinized form of 

 it. :My species will become Tritseta antarctica, and will probably include as synonyms, 

 Polycheria tenuipes, Haswell, from Port Jackson, and Polycheria obtusa, Thomson, from 

 New Zealand. 



Another new species, described and figured as " Seba Saundersii," is said to come from Algoa Bay, 

 South Africa. In 1883, a new genus and species from New Zealand was described by 

 Mr. ChUtou under the name Teraticum typicimi. This is probably the same as my 

 Seba saundersii. A specimen brought home by the Challenger was taken in the Strait of 

 Magellan, so that the range of this little species in the south would seem to be very 

 extensive.
