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



" Carnivorus cancellus retia corrodit et forsitan fulgorem maris pontici (an quoquo caspii 1) noc- 

 turnum efficit ; constat enim observationibus, Gainmanim locustam nocturna luce sjilendere 

 in germanico mari. (v. Desmarest considerations generales sur la classe des Criistaws, Paris 

 1825 pag. 267)." 



Boeck thinks that this Gammarus hxmohaphes is much the same as Gammams locusta. Spence 

 Bate does not notice it in the Brit. Mus. Catalogue. 



1841. Gould, Augustus Addison, born April 23,1805, died Sept. 18, 1866 (Encycl. Brit., 

 9tli Edition). 



Eeport on the invertebrata of Massachusetts, comprising the Mollusca, Crustacea, 

 Annelida, and Radiata. Published agreeably to an order of the Legislature, by the 

 Commissioners on the zoological and botanical survey of the State. Cambridge, 

 1841. 



The Crustacea occupy pages 321-341. At page 333 the account of the " Amphlpoda " begins, 

 followed by that of the " Loemipoda." The following notes are given : — 



" Genus Oechestia, Leach. O. longicornis. TAlitrus longic6rnis. Say ; Journ. AcaJ. Nat. Sc, 

 i. 384. This appears to be the same as Cancer gammarus salthtor of Montagu (Trans. Lin. 

 Soc, ix. 94, tab. 4, f. 3,) which is given as synonymous with TiUitrtis locusta of Lamarck, 

 Pennant, and others. But it is not Gammarus loaista of Montagu. 



" 0. GRYLLUS. TAlitrus gryllus, Bosc ; Hist. Nat. des Crust., ii. 104. Say ; Journ. Acad. N'at. 

 Sc, i. 386. The following seem to be synonyms, viz. T^litrus gamar^Uus, Latr. and Lanj. 

 Orchestia littori^a. Leach; Tran.s. Lin. Soc, xi. 356. Desm.; Consid., &c., 261, 

 pi. 45, f. 3. 



"Genus G.\mmarus. G. lociJsta, Montagu; Lin. Trans., ix. pi. 4, f. 1. Milne-Edw.; Ann. 

 des Sc. Nat., xx. 367. This is not G. lociista of Pennant, Gmelin, Pallas and Fabricius, 

 which is a Tdlitrus. 



" G. MiNU.s, Say; Journ. Acad. Nat. Sc, i. 576. Found in ditches and sluggish fresh water, 

 adhering to sticks. 



" Two or three other species of ORCHfeTiA, and one of AiipniTHOE, remain undetermined. 



" Genus HypfeRiA, Latr. H. Galea. Gammarus Galba, Montagu ; Lin. Trans., xi. pi. 2, f. 2. 

 The following are doubtless synonyms: Oniscus medusarum, 0. Fabr.; Fauna Groenl., 275. 

 Hyperia Sueurii, Latr. Hyperia Latreillii, Milne-Edw.; Ann.des Sc Nat., xx. 388, pi. 11, 

 f. 1-7. This curious animal is found in the pouches of the Medusae or Sun-fish as they 

 are commonly called. "Whether they make this their home, or whether they become en- 

 trapped there or not, it would be difficult to determine. They seem, however, to be quite at 

 their ease in this situation. 



" Another animal with long, many-jointed antennae, was found in company with the above, 

 which belongs either to the same genus, or to the genus Hieraconyx. 



"LcEMiPODA. Genus Cyamus, Latr. C. cbti, Latr.; Gen., i. 60. Desm.; Consid., 280, pi. 46, 

 f. 4. Edwards; Ann. des Sc. Nat., 2d Series, iii. 328, pi. 64, f. 13, 14. Oniscus ceti, 

 Lin.; Mull. Laninda ceti. Leach. The whale-louse may be properly enumerated among 

 our Crustacea, as it is found on the whales which are occasionally caught on our coast. It 

 varies in form, according to its degree of development. 



" Genus Caprella, Lam. I have observed two species of this curious genus, neither of which 

 can I refer to any described species. One of them is very delicate, about half an inch long, 

 with no spines upon any part, that I can discover, and having its back thickly dotted with 

 dark green.
