 actions of the first meeting of Eussian naturalists at St Petersburg, 1868, 4to, 

 pp. 176-179 (written in Russian).] 



" The so-called Leydigian organs on the first pair of antennae, first observed by La Valette m 

 Gammarus imtemms, and afterwards accurately described and stated to be sensitive organs 

 by Leydig, are the subject of a paper by F. Jarschiuski (7. c), who has observed them in 

 various genera of Amphipoda." (Dr. von Martens, Zool. Record for 1870.)

Fries refers to a paper in the above Transactions, and another in "Amtl. Bericht derMtinchner 

 ISTaturforscher-Versammlung, 1877 (p. 172)," in which G. Joseph records the occurrence of 

 a blind Gammarid {Nlplianjus orcinus, n. s.) in the brooks of the hill-grottoes of Carniola, 

 which probably from these reaches the lake of Zirlenitz, where it can be freely gathered. 

 It comes to the surface after sunset in calm weather.

Packard's new species, Monoculodes nuhilatus, mentioned on p. 613, is called Monoculodes 

 nuheculatas on p. 617. It is stated that "the genus Pontoporeia is reunited with 

 Lysianassa " by G. 0. Sars in his Hist. Nat. des. Crust, d'eau douce de 'Novv&ge, p. 82, note. 

 But Sars only says, "0. vaudrait peut-etro mieux les r^duire, en attendant, k un seul 

 genre." In the text he retains the name Pontoporeia.

At page 56, under the heading " Tetradecapoden," Martens notices the continental and terrestrial 

 habits of some members of the genera Gammanis, Talifrus and Orchesiia. In Madeira he 

 had met with a Gammarus, which was more frequently to be found on the banks of the 

 brooks than under water ; in Japan an Orcliestia presented itself " am Waldrande, Zwischen 

 abgefallenem feuchtem Laube, aber doch nicht im Wasser." After referring to Dana's 

 Orchesiia sylricola from New Zealand and Orchesiia iahiieiisis from Tahiti, and Heller's 

 Orchesiia cavimana from Cyprus, he describes the Japanese species as Orchesiia humicola,
