EEPORT ON THE AMPHIPODA. 373 



said to bear a close resemblance to Orchestia euchore, Miiller. As Boeek identifies the latter 

 ■with Orchestia gammarellits, this species also may be a variety of the same. 



A short account is given, and the second gnathopod figured, of Kr0yer's Leucothoe clypeata, 

 under the name Montagua clypeata, with the suggestion that Mo7itagua pollexiana, Spence 

 Bate, may be the male of Kr0yer's species ; in that case it would become a synonym of 

 Metopa di/peata, Kr0yer. The second gnatliopod of Montagua norvegica is figured and 

 described, with a reference to Leucothoe norvegica, Liljeborg, 1850, and to the Brit. Mus. 

 Catal., p. 370, where Spence Bate expresses the opinion that this species is most probably a 

 synonym of Montagua chjpeata. Boeck agrees with this view, naming it therefore Metopa 

 chjpeata, Kroyer (but see Note on Liljeborg, 1850). 



At page 501, Opis leptochela, n. s., is figured and described. Of this Norman, Last Eeport, etc., 

 p. 335, 1868, says, " this I find to be the species described by me under the name Euonyx 

 chelatus (Brit. Assoc. Report 1866 (1867), p. 202). My specimen differs from that described 

 by B. and W. in having the second gnathopods larger and stronger than the first, and the 

 hand furnished with a strong nail. This difference is perhaps one of sex. The species 

 cannot, I think, be placed in the genus Opis." Boeck, apparently unaware of Norman's 

 genus, says of Opis leptochela, that it cannot belong to Opis, " as the first gnathopod has a 

 very elongate wrist and an elongate chelate hand, thereby resembling the genus Kroyeria, 

 which belongs to the subfamily ffidicerins. It ought therefore to become the type of a 

 new genus, which might be called Leptochela." 



At page 503, Opis quadrimana, n. s., is described, and the first gnathopod figured. On the 

 ground that this does not agree with Opis either in the mouth-organs or the structure of the 

 first gnathopods, Boeck, in 1870, makes it the type of a new genus, under the name 

 Normania quadrimana. Bate and Westwood. 



A species is partly figured and described as probably belonging to Anipelisea Iwoigata, Lilljeborg, 

 but by Norman and Boeck the form in question is said to be Ampielisca tenuieornis, 

 Lilljeborg. Haploops tuhicola, Lilljeborg, is figured and described, and said to have been 

 taken by Mr. Norman " in the Shetlands," where " Hebrides " should be read instead of 

 " Shetlands." 



At page 507, Monoculodes longimanus, n. s., from Banff, " length about one-fifth of an inch," is 

 briefly described, and the first and second gnathopods are figured. " Specific character. 

 Dorsal surface slightly carinated. First pair of gnathopoda long and narrow, resembling the 

 second pair." 



At page 508, Kroyera hrevicarpa, n. s., is described. The gnathopods are figured. This is 

 identified by Boeck with Kroyeria haptlocheles, Grube, 1864, and therefore named Ponto- 

 crates haplocheles. 



At page 509 the new genus Lepidepecreum is defined as follows : — " Cephalon having the orbital 

 or intra-antennal process considerably developed and produced. Pereion well-developed. 

 Pleon having the last four segments very short. Eyes not made out ; supposed to occupy 

 the intra-antennal process ; — superior antennre having the upper surface of the first two 

 joints of the peduncle considerably produced anteriorly, having no secondary appendage. 

 Inferior antennaj posterior to the superior. Mandibles furnished with a biarticulato 

 appendage. First pair of gnathopoda moderately robust, subchelate. Second pair feeble 



and chelate or subchelate. Posterior pair of pleopoda short, biramous. Telson ? " The 



type is figured and described as Lepidepecreum carinatum, n. s. It was " taken at Banff 

 by Mr. Edward, associated with Anonyx longicornis, with which it is very closely allied, 

 being perhaps a young female." There seems little, I think, to justify the establishment of 

 a new species, and the name for the two forms should therefore stand as Lepiidepecreum 

 longicorne. In the description of Anonyx longicornis, the telson was given as " very long 

 and deeply cleft," so that " telson cleft " may be presumed to be properly part of the generic
