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



Podocerus pulcliellus, Leacli, and Podocerus 2KJariicus with the earlier Pudocenis falcatus, 

 Montagu. He describes a new species, " Oiihopalame TersclieUingi" thus defining the new 

 genus Orthopalame, "Epimera anteriora quinque magna, quinto iu margine posteriore non 

 inciso. Antenna? superiores flagello elongate, flagello accessorio parvo 2-articulato. Antennae 

 inferiores non subpediformes, superioribus parum breviores, flagello multiarticulato. 

 MandibuljB robustse, palpo elongato, 3-articulato, articulo tertio palpi non perdilatato. 

 Pedes 2di paris iisdem primi multo validiores. Pedes saltatorii ultimi paris uniramosi. 

 Appendix caudalis recurvata, hamulo parvo armata," and further remarking that it has 

 affinities in some repeats with Cerapus, in others with Ampihithoe. He suggests that the 

 gland in the first joint of the first and second perseopods will be found common to all the 

 Corophida3, and connected with their mode of life in building nests or lining their excavated 

 passages, a matter on which S. L Smith in the following year puhlished some interesting 

 observations (Trans. Connect. Acad., vol. iv., July 1880). 

 ni. On an Orcliestia from terra firma. The OrcJiestia in question was found in a walled garden 

 in the town of Zalt-Ijommel iu the province of Gelderlaiid, many miles from the sea, and is 

 identified by Dr. Hoek with Orcliestia cavimana, HeUer, taken on Olympus in Cyprus at a 

 height of 4000 feet. 



IV. On some insufficiently known Gammarids. These are — 1. Afi//us sicannuerdammii, Miliu;- 

 Edwards ; 2. CaUi(qdu^ /ccriusruinf, Krciyer, on which Dr. Hoek observes that the genus 

 Calliopius is intermediate between the Atylinae, to which Boeck assigns it, and the 

 Gammarina3 ; 3. Mdita ohhisata, Montagu, as to which he adopts Norman's statement that 

 Melita proxima, Bate and Westwood, is the most frequent form of the male of MelUa 

 ohtusata, and Megamoera alderi, of those authors, its female; 4. Gheirocratus hrevieornis, n. s., 

 which, however, is the same as Cheirocratus sundevalli, Rathke, and has also been described 

 under the names Li!Jehoir/ia sJietlandica, Sp. Bate, and Liljehorgia norrii.anni, Stebbing, 

 though some of its characteristic points were first clearly brought out by Dr. Hoek ; 

 5. Ampelisca aeqinroryu'g, Bruzelius, is distinguished from Ampclisca leevhjata, Lilljeborg ; 

 Tetromcdus typicus, Sp. Bate, later incorrectly identified by Sp. Bate with Ampi'lisva 

 fjaimardi, Kr0yer, and by Norman and Boeck and Hoek considered synonymous with 

 Avqielisca carinafa, Bruzelius, and by Sars with Ampelisca tcnuicornls, Lilljeborg, is here 

 attached, in accordance with Norman's suggestion, to Ampelisca xipucornis, Bruzelius, as the 

 male form. But Bate's species is distinct, and is entitled to the name Ampclisca fijpica, if a 

 species which is not the type can lawfully be called ti/pica; see discussion in Note on Sars, 

 1882. 



V. Short anatomical notes on Gammarids, referring to the structure of the anteuuie with their 



" calceoli," etc., and to the branchiae of Atylus swammerdammii.

In regard to the Niplinnjus indeanus from Venice, it is shown that their introduction into the 

 carefully covered wells (Pozzi) of Venice is best explained by the transport of water from 

 the mainland to replenish these wells in the dry season.
