size, shorter antennas, and clifTerences in the gnathopods. He gives its length asf3 mm. 

 The length given by Boeck is 2 mm. Bruzelius says the body's length is about 2 mm. 

 Leucothoa norvegica, Liljeborg, is next described. Of this he says in a note that it is possibly 

 the male, and Leticotlwe chjpeata the female of one and the same species, an opinion in 

 which Bate and Boeck agree with him. 



After describing Leucotlwe articulosa, Montagu, and " Laphystius Sturionis," Kroyer, he defines 

 the new genus Nic.ippe : — 



" Corpus crassiusculum, epimeris mediocribus. Antennae graciles, superiores flagello appendicular! 

 ornatae. Mandibulae dissimiles, palpis e ternis articulis compositis instructs, altera processu 

 accessorio sive ramo interno carens, altera eodem priedita. Palpus maxillae primi paris 

 biarticulatus. Pedes maxillares laminis minutis et palpis e quaternis articulis compositis. 

 Pedes primi secundique paris manu subcheliformi armati. Tria paria posteriora pedum 

 thoracis postice gradatim longitudine crescentia. Pedes abdominis sexti paris biramei, ramis 

 nniarticulatis." The type species is Nicippe tumida, n. s., pi. iv, fig. 19. Lastly he 

 describes Pardalisca ciisjndata, Kroyer.

The investigations were made upon " Gammariis locusta, Linn6, and Ampldtlwe podoeeroides, 

 Rathke." Sars, 1867, in regard to the inner structure of the Amphipoda, says, " nous devons 

 les Etudes les plus consciencieuses et les plus exactes au savant suedois, M. Ragnar Bruzelius, 

 . qui a ecrit sur ce sujet un m^moire accompagne d'une planche lithographiee dans ' Ofversigt

 suite, mes recherches sur cette espfece [Gammarus neglectu8\ s'accordent parfaitement, dans 

 tous les points essentiels, avec les communications de ce naturaliste, fait qui merite ici une 

 attention particuliere, attendu que les renseignments fournis par d'autres savants, entre autres 

 par M. Spence Bate, semblent s'en ^carter sous plusieurs rapports."

Amphipoda are mentioned on pages 7-9, but without any descriptions. One new species is 

 noted under (Edicerus, Kr0yer, " 0. arcticus u. spec. Af denne nye Art fandt jeg nogle 

 faa Exemplarer ved Vads0e paa sandig Leerbund fra 40-60 Favne." This is regarded by 

 Boeck as a synonym of CEdiceros lynceus, M. Sars, 1859.
