REPOET ON THE AMPHIPODA. 271 



2:dra ser. 1 band., p. 403)," includes among the Crustacea from Drilbak, a species under 

 the name of Ampelisca rotundata Kroyer, a name which lapses for want of attendant 

 description. 



Ampelisca maerocepJiala, n. sp., is described, this being a species which in 1851 Liljeborg 

 had supposed to be "Ampelisca Egchrichfi Kroyer." AinpMthoil jwdoeeroides, Rathke, he 

 found much smaller here than on the coasts of Norway. 



Amphitlwe I'ompresga, n. s., here described, and thought to be very like AmphitJioe tenuicomis, 

 Rathke, was called Atylus compressus by Spence Bate, and later identified by Boeck witli 

 Atijlus moammerdamii, M.-Edw. 



AmpMtlwe pygmxa, n. s., is identified by Boeck with Photis reinhardi, Kr0yer, 1842. Liljeborg 

 thought it something like Iphimedia ohesa, Rathke, which, he remarks, had anticipated 

 Kr0yer's Microchele^ armnta, 1846. In the list of v. Dueben's Crustacea, 18.51, he 

 had given "44. Ipliimcdia obesa, H. Rathke. 45. Microcheles armata Kr." He there- 

 fore here observes that the latter had proved to be a young specimen of CEdif.erox 

 .iaginat?n<, Kr. 



Under Gammarus locusta (Lin.), he gives " G. Duebeni Liljeb.," as a synonym, and this 

 description, " Oculi reiiiformes nigri, antennas superiores longiores, flagello appendicular! 

 5-7 articulate ; rami pedum spuriorum ultimorum insigniter inaequales, interior exteriore 

 saltern tertia parte minor. — Vulgaris." 



He describes Gammarus maculafus, n. sp., the name being preoccupied by Johnston, and the 

 species being, as Liljeborg afterwards recognised, Montagu's, now known as Melita ubtusafa. 



Gammarus longip)es, n. s., which he thinks very like his own Gammarus assimilis, 1851, was 

 called Autonor hmgipes, by Bruzelius. 



In " Hyperia LatreilU M.-Edw.," he notes that the young differ from the adult in respect to the 

 antennte. An account is appended by S. Lov6n of the tubes constructed by Ampelisca 

 eschrifldi, Kr0yer. Several specimens taken on one occasion in their tubes, proved to be 

 all females. The close proximity of the tubes taken on another occasion suggested that the 

 species might be gregarious.

 Mr. William Penny, in search of the missing crews of H.M. Ships Erebus and 

 Terror. London, 1852. 



" In the neighbourhood of Ben-y Island dredging was frequently attended to," and " the display, ' 

 he says, "of animal and vegetable life before us, when the dredge was emptied, was really 

 wonderful. Whole heaps of MoUusca, Crustaceans, Annelidans, and Echinodermata t-oiUd 

 be seen tumbling out from among masses of sea-weed." Sutherland says that the sea- 

 bottom there is "the habitat of myriads of creatures belonging to the genus Cajvella, 

 Cyclops, Gammarus, etc." (p. 140). On p. 142 he gives a striking account of the voracity 

 of the Gammarins, naming especially Gammarus arcticus. Whether it were a dead seal or 

 a live sucking-fish (Lepadogaster), short work was made of their prey. 



In the Appendix, vol. ii. pp. ccvi, ccvii. White describes, according to Boeck, " Gammarnx 

 nngax, Sab., Aeantlionohis tricuspis, Kr., Amphitho? Edirardsii, Sab., and Stegoce2:>haln.< 

 inflatus, Kr.; a species of Anomjx, and lastly Cajjrella eercopoides, n. s., which falls to 

 CapreUa septentrumah's, Kr." Mayer in 1882 think.s that, judging by the figure, Boeck'.s 

 view of Caprella rercopioides is probably correct.
