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



character. G. 0. Sars, 1882, mentions the capture at Lorlshavn of a single specimen (?) of 

 " Lepid&pecreum carinatum, Sp. Bate," but does not describe the telson. In a specimen 

 wliich I owe to the kindness of Mr. David Robertson of Glasgow, I find the telson very 

 narrow, cleft almost to the base, each tip having two small spines. Sars thinks that 

 Lysianassa umbo of Goes should be included in this genus, and not in Boeok's Orcho7nene. 

 See Note on Goes, 1865. 



Nicippe tuviida, Bruzelius, is figured and described. 



Cheirocratus mantis, Norman, is figured and described, but with some variations in the generic 

 character, which need correction. The upper antennas are much shorter than the lower, 

 not subequal, and the third uropods are not unibranched, but biramous. The species is 

 identified by Boeck with the earlier Cheirocratus assimilis, Liljeborg. 



At page 515, Megamcera multidentata (Norman, MSS.), from Guernsey, is figured and described. 

 This is " Moera Batei," Norman, published in the Annals and Magazine of Natural History 

 for December 1868, and therefore taking precedence by a few days of the name Megavicera 

 multidentata. This is indicated at page 530 by the citation, " Mcera Batei Norm. (See 

 our Vol. ii p. 515)," but no notice is there taken of some slight discrepancies between the 

 two accounts, which were no doubt drawn up from different specimens. 



On pages 517-518, Norman's Unciola planipes \s figured and described as Unciola leucopes, 

 Kr0yer, Krpyer's genus Glaiiconome being identified with Unciola, Say. Norman, Last 

 Report, etc. 1868, says, " Unciola leucopes, Kroyer. B. and "W. consider my U. planipesas 

 ' probably identical ' with this species. It may be so, but there are points of difference 

 which make me think it wiser to keep them apart until the examination of GreeiJand 

 specimens should settle the question definitely." Kr0yer's species, it should be observed, 

 was named leucopis from "Xcvkos, albus, et o^, oculus." Boeck gives " ? Unciola planipes, 

 Norman," as a synonym to his own Glauconome kr(pyeri, 1870. Sars in 1882 accepts 

 Glauconome leucopis. Kr0yer, as identical with Unciola irrorata. Say. 



Hyperia tauriformis, n. s., from Banff, briefly described and partly figured on page 519, is 

 identified by Norman with Metoecus medusarum, Kr0yer, which Boeck names Tauria 

 medusarum, O. Fabr., 1780, but Bovallius, 1885, points out that Bate and Westwood, and 

 Boeck likewise, have misunderstood Dana's account of his genus Tanria, so that neither the 

 name Hyperia tauriformis nor Tauria medusarum is admissible. The name wiU perhaps 

 become Hyperia ahyssorum, Boeck. 



On page 520, Hyjieria prehensilis, n. s., from Banff, is figured and described. " Sj/ecijie char- 

 acter. Superior antennae about the length of the head. Both pairs of gnathopoda vnth the 

 carpus and propodos simple. Three liind pairs of pereiopoda subprehensile at the tips." 

 Length, three-twentieths of an inch. 



On page 521, Hyperia cyanex, Sabine, is described. " It looks like a young H. Galba, with 

 rudimentary antennse, but one of the specimens sent to us had the incubatory pouch of the 

 adult female fully developed, so that we cannot mistake it for a young animal." By Boeck 

 Sabine's species is identified with Hypei-ia medusarum, 0. F. MiiUer. 



Themisto crassicomis, Kr0yer, is next figured and described, a species which Boeck identifies 

 as Tliemisio libellula, Mandt. 



On pages 534-535, Vibilia horealis, u. s., from Banff, is figured and described, a letter from 

 Thomas Edward, on its habits and colouring, being quoted. 



In the Supplemental Notes, among other matters of interest, the names are mentioned of the 

 genera and species of which A. M. Norman had published descriptions in December 

 1868. 



The Introduction, signed C. S. B., is a general account of the structure, functions and distribu- 

 tion of the Amphipoda.
