fresh water, the latter in small rivers about 1000 metres above the sea ; 
F. MCller, Ann. N. H. (5) ii. p. 427. [The same already known from 
the collections of Dr. Hensel ; Arch. f. Nat. 18G9, pp. 1-32.] 
New Zealand. 11 species of terrestrial Isopoda and some subterrestrial 
Amphipoda are to be found in Miers’s Catalogue of the Stalk- and 
Sessile-eyed Crustacea of New Zealand, 1876, pp. 94-103 & 122. [It is to 
be regretted that it does not appear from this Catalogue which genera or 
species live in the fresh waters of New Zealand]. Pakemon {Leander) 
Jluviatilis, Calliope fluviatilis (Amphipod), and Idotea lacustris, spp. nn., 
fresh waters of New Zealand, the two latter the first freshwater species 
of their genera ; Thomson, Tr. N. Z. Inst. xi. pp. 231, 240, & 2.51. 
F. A. Fokel discusses the fauna of the Swiss lakes, distinguishing (1) 
The littoral fegion. (2) Pelagic region, in the water of Lake Leman ; 
Leptodora hyalina, Bythotrephes longimanus^ D.^phnia hyalina and mucro- 
nata^ Bosmina longispina^ Sida crystallina, Cyclops hrevicaudatas^ Diap- 
tomus castor ; they live during night near the surface, during the day in 
depths of 10-50 metres, swimming. (3) Deep region at the bottom of 
Lake Leman, 15-334 metres where only a few cryptogamic plants exist, 
such as Oscillaria^ Pleurococcus, and 21 Diodomacece ; the Crustacea of 
this region are — Niphargus pmteanus^ Y 2 cr.foreli (Humb.), Asellus sieholdi 
(Rougem.), Lynceus lamellatus, macrurus and striatus, Candona reptans, 
Acanthopus sp. (Vernet), Cypris sp., Cyclops sp., and Canthocampjtus 
staphylinus. Those of the pelagic region are the same in the different 
lakes, and may be easily transported from one to the other by water- 
birds, &c. ; those of the depths are peculiar in each lake, and are derived 
from nearly allied species living in the littoral region of the same lake.

Thirty-fi re species of Cladocera observed near Leipsic by A. Lutz, SB. 
Ges. Leipzig, v. pp. 36-41. 
North America. 37 species of freshwater Cladocera^ of which 17 are 
identical with European and one represents a new genus, are described 
by E. A. Birge (Wisconsin : 1878, 8vo, 34 pp., 2 pis.) ; they have been 
in Wisconsin and Massachusetts. 
Colorado. Some new Phyllopods described by Verrill, Bull. U. S. 
Geol. Surv. iii. pp. 171-181, woodcuts. 
New Zealand. Some species of Lepidurus^ Daphnia, Chydorus (Lyn- 
ceidce)y Cypris^ and Cyclops, most of them new, from fresh T^ater, described 
observed by Thomson, Tr. N. Z. Inst. xi. pp. 253-262. 
Kerguelen Island. Four species of Cladocera, 1 Ostracode, and 2 
Cyclopidce found in freshwater ponds, all new, but belonging to European 
genera ; Studer, Arch. f. Nat. xliv. pp. 102-111, pis. 2 & 3. 
A. Gruber, Siisswass. Calanid. pp. 3 & 9, enumerates the known fresh 
water Calanidce, viz., 3 species of Diaptomus, 2 of Heterocope, 1 Limno- 
calanus, and 1 Temora; two of them have been observed by himself in 
the lakes of Southern Germany, and he remarks that the Entomostraca 
which live in great lakes are generally more pellucid and less prolific 
than those living in small ponds.
