ADDENDA. — Since the earlier part of the Index was printed, E. Chevreux has described Ampelisca sarsi, n. sp., and 

 .E'jiita capillacea, n. sp. For Phxdra kinaJuini, Sp. Bate, in accordance with the suggestion of Boeck, 1876, he adopts the name 

 Lilljcborgia [Liljcborgia] kinahani. His paper is entitled, "Nouvelles especes de Crustaces Amphipodes du sud-ouest de la 

 Bretagne. Association francaise pour l'avancement des sciences Fusionnie avec l'association scientifique de France, Congres de 

 Toulouse. — 1887. Paris, 1888." Another paper by the same author is entitled " Contribution & l'etude de la distribution 

 geographique des Amphipodes sur les c6tes de France. Extrait du Bulletin de la SociMe d'etudes scientifiques de Paris, ll e annee, 

 l er semestre 1888." No new species are described, unless it should prove that one which is named " ? Caprella spinosissima" is 

 in fact novel. 



" Les Plages du Croisic, recoltes zoologiques par Adrien Dollfus avec la collaboration de MM. Ed. Chevreux et Ph. Dautzen- 

 berg, Paris, 1888," is another recent addition to the literature of the Amphipoda. No new species are described. 



In a note dated Stazione Zoologiea, Napoli, November 19, 1888, Dr. Mayer informsme that he has quite recently seen specimens 

 of dSginella spinosa, Boeck. From the examination of these he is inclined to keep ^Eginclla distinct from Kr0yer's JEgina. 

 Should this eventually be considered necessary, whatever new generic name may be substituted for the preoccupied ^Egi-iui will 

 apply to the species cchinata, Boeck, longicoriiis, Kr0yer, and s2>inosissima, Mayer, while aculcata, Dana, tenella, Dana, aud 

 tristanensis, of this Report, will remain indeterminate as regards their generic position (see pp. 1248, 1686). 



In re-examining the Challenger collection of Gammarma, I find that in a few instances some duplicate specimens have been 

 omitted from the enumeration given in the text, and that one addition must be made to the series of specimens obtained from 

 below 300 fathoms. For this last the following preliminary description may here suffice:— 



Genus Pardaliscoidcs, 1 n. gen. Near to Pardalisca. Peduncle of the upper antennae not very short. Palp of first maxillae 

 of moderate breadth. Outer plate of the maxillipeds narrow as well as short. The perseopods slender; the third joint in the 

 first and second pairs moderately long, not dilated. Telson shorter than the peduncle of the third uropods/divided nearly to the 

 base, dehiscent. 



Pardaliscoidcs tenellus, n.sp. Rostrum acute. In the upper antennse the second joint of the peduncle narrower but rather 

 longer than the first, the third joint longer than broad; the secondary flagellum elongate, with eight joints remaiuing. Lower 

 antennae having the fourth joint of the peduncle longer than the fifth, and about equal in length to the nine-jointed flagellum. 

 Mandibles, first maxillae, and gnathopods having a general resemblance to those of Pardalisca abyssi, the second maxilla; to those 

 of Pardalisca rnarionis, the peneopods and telson to the figures given by Bruzelius for Nieippe tumida. There are three spines in 



1 In the Introduction, p. xxii, it should have been stated that two specimens were obtained of Elamwpus delaplata, and two of Podocerus h> 

 To include these together with Paradaliscoides tenellus, the statistics should he that in the 34 specimens 26 genera are represented, of which 11 are 

 new, aDd 29 species, of which 27 are new. On p. xxiv, line 4, for thirty -one read thirty-two, and line 2S, for Prestandres read Prestandrea.
