CRUSTACEA. 
NEBALIIDiB. 
Nebalia. Prof. C. Claus's researches on N, geoffroyi (M.-E.) 
confirm MetschnikofF's view that this genus belongs to the 
Malacostracaj near the Mysidce ; the more striking differences 
from the rest of the Malacostraca are, however, the abdominal 
segments being 8 instead of 6, and the double telson; the 
thoracic feet are only apparently similar to those of the Phyllo- 
pods, on account of their lamellar shape ; but really all their 
parts can be reduced to those of the MysidiB, The male is 
similar to the female in size and general shape ; but the flagellum 
of the lower antennae is much longer (nearly as long as the body, 
composed of 80 joints), and the terminal bristles of the thoracic 
feet, which serve for ventilation in the cavity of the shell to the 
female, are much smaller, nearly rudimentary. Z. wiss. Zool. 
xxii. pp. 323-330, pi. 25. 
Squillid^e. 
Squilla rubroUneata (Dana)? = dubia (M.-E.), described from Cuban speci- 
mens by Martens, Arch. f. Nat. xxxviii. p. 144 & 145} S, stylifera (Lam.), 
from Cuba, identical with specimens from the East Indies, id. ibid. p. 140. 
Qonodactylus ckirayra (L.) } Cuban and Indian specimens not positively 
distinct ; id. ibid. p. 147. 
AMPHIPODA. 
A. Boeck has commenced a monograph of the Northern and 
Arctic Amphipods, the first part whereof contains introductory 
repaarka upon morphology, chiefly concerning the epistome, 
feelers, upper lip, mandibles, first maxillae, under lip, second 
maxiUae, maxillipeds, trunk of the body, postabdomen, and re- 
spiratory and ovigerous plates in the Caprellida, both of which 
plates are fixed on the 7th joint of the feet ; but the former is 
always wanting to the first, the latter to the first and second 
pair of feet, pp. 3-13. Then follows an alphabetical list of the 
literature of the Amphipods down to the year 1870, containing 
273 titles of books or published papers, pp. 14-31, a chrono- 
logical record of the more important of them, beginning with 
the sea-flea mentioned by Aristotle, pp. 32-58, and an account 
of their geographical distribution (see above), pp. 59-63. In 
the special part, the same classification is adopted as in a pre- 
vious paper by the same author (see Zool. Rec. viii. p. 187), only 
changing names of the two chief divisions from Hyperidce 
and Gamrlmridce into Hyperina and Qammarina. The present 
part reaches as far as Anonyx.
