254 THE VOYAGE OF H.M.S. CHALLENGER. 



1852. Couch, Richard Quiller, bom March 14, 1816, died May 8, 1863 (W. Pengelly). 



On some of the rarer forms of Cornish Crustacea. Transactions of the Natural 

 History and Antiquarian Society of Penzance. Volume II. 1851-1855. Penzance, 

 1864. (Report for mdcccli, apparently published in 1852.) pp. 95-99. 



In '^ Class Crustacea, Suliclass G. mandilmlata," Couch gives dethiitions of the two genera 

 CapreJla and Pri>tn. In the first he describes 1. Oaprella phmma, Montagu's Cancer phasma ; 

 2. "C.4eawi!7w/e)-a," for whichhe gives "a ^ca«Ww/e?-a, Johnston, Mag. Nat. History, Vol. vi., 

 p. 40, fig. 7a;— Vol. viii. fig. 70, p. 671.", as his authority ; 3. " G. Pe.miantii," with 

 references to " Gancer Atomos, Stew. Elem., Vol. ii., p. 317 ; Astanis Atomos, Pennant, Brit. 

 Zuol., Vol. iv., PI. 13, fig. 2."; 4. "C. Linearis," with reference to Cancer linearis, Liu., 

 Cancer lohafm, Stewart, Caprella linearis, Johnston; "the head is obtuse, and the species 

 the shortest and stoutest of any found in our seas, with no spine along the whole of the 

 dorsal sm-face." C. spinulafa (Couch), is thus described : — " Long and slender ; the head is 

 larger than the next articulation, and without a spine; the occipital articulation with a spine 

 near its posterior margin, and there is one on the next ring above the branchife ; there are 

 two on the third, one above the branchiw, one near its posterior margin, and one on the 

 centre of each of the others. Superior antennce as long as the body, basal joint small, the 

 second about four times as long as wide, the third long and slender and slightly enlarged 

 towards its distal extremity, the last multi-articulate and ciliated ; the inferior autenn» 

 much smaller than the others ; at the lower part of the head two pedipalpi, small and bifid 

 at their extremities. The hand very large, moveable joint long, slender, and hooked, and at 

 its point, when bent, touches a spine on the hand." Mayer thinks these characters would 

 suit C. acanthi/era, but recognises the uncertainty. The "occipital articulation with a spine" 

 is a little suggestive of ^ijiiieUa spinosa, Boeck. Lastly, he describes Protn pedaius, 

 without naming any authority. 



1852. Dana, James D. 



Conspectus Crustaceorum quae in Orhis Terrarum circumnavigatione, Carolo 

 Wilkes e Classc Reipuhlicee Fcederatse Duce, lexit et descripsit Jacobus D. Dana. 

 Pars III. Amphipoda. No. I. Proceedings of the American Academy of Arts 

 and Sciences. Vol. II. From May, 1848, to May, 1852. Boston, Cambridge, 

 1852. pp. 201-220. 



This paper contains only Dana's own new species. In "Subtribus 1. Gamniaraoea. Familia 1. 

 Orchestidai. PaJpzis maiulibularis obsoletus. Corpus compressnm, epimeris latis. Stt/li 

 ccmdales duo postici breviores," he gives genus I. Talifrus, Latreille, " Pedes primi stjdi- 

 formes, secundi vel non subcheliformes vel manu debilissima confecti. Antennx prima basi 

 inferiorum breviores," with the s]iecies Novi-Zealandia;, gracilis, ornafus; genus II. Talifronus, 

 Dana, " Pedes secundi manu valido prehensili confecti. Alias Talitru similis," with the 

 species inscuJphis which he afterwards identified with Orcliestrndea tuberculata, Nicolet, as 

 an Orchestia, dropping both his own genus TalHronus and Orchestoidea of Nicolet ; genus III. 

 Orchesfia, Leach, with the species sijlncola, tenuis, reciimamis, spinipahna, scufiijerula, 

 nitida, dispiar, quadrimaiius, serrulafa; genus IV. Allorchestes, Dana, with the specie.? coni- 

 pressa, verticillafa, hirfipalma, gracilis, pierudana, liumilis, australis, hrericornis, Nari- 

 Zealandix, inirepida, orienialis, and Allorchestes? graiuinea.
