A few observations concerning Chinese freshwater crabs, kept alive for 
40 or 60 days and used extensively as food, are to be found in Cooper’s 
* Pioneer of Commerce,’ p. 424, extracted in Ann. N. H. (4) viii. p. 72. 
For Hagen’s monograph of the North- American Astacidm 
see p. 185. 
Verrill has observed, in the depths of Lake Superior, My sis 
relicta and Pontoporia affinis, both identical with individuals 
found in Lake Wettern, in Sweden, by Loven, and describes 
some other Isopods found in the same lake : Am. J. Sc. (3) ii. 
pp. 374 & 452. Stimpson has found also a species of Mysis, 
probably M. relicta^ in Lake Michigan : Am. Nat. iv. p. 404. 
Some Crustacea found in caves of N. America are mentioned by Cope, Ann. 
N. II. (4) viii. p. 308. 
The N.-American Phyllopoda are the subject of a paper by Packard, ibid. 
p. 332, and the Ostracoda by G. S. Brady, Oanad. Nat. v. no. 4.

Podochela gracilipes, sp. n., Stimpson, Bull. Mus. C. Z. ii. p. 126, reefs of 
Florida Straits. 
Podonema [as Podinema, preoccupied in Peptilia\ g. n., differs from Podo- 
chela in its hood-shaped rostrum and the existence of lamelliform ridges in 
the region of the pterygostoma, defining the afferent channels. P. {Podochela) 
riisii (Stimps.) and P. lamelligera and hypoglypha^ spp. nn., Straits of Ilorida :

Stimpson, I, c., characterizes the following new genera and spp. &c. : — 
Collodes trispinosus and nudus, Florida, pp. 120 & 121. 
Arachnopsis^ differing from Collodes in its filiform ambulatory feet and long 
eye-peduncles. A.Jilipes, reefs near Florida, 34-45 fathoms, p. 121. 
Batrachomtus^ characterized by the want of a terminal spine on the basal 
joint of the antennae, and in its very long anterior and short posterior ambu- 
latory feet. B. fragosus, Straits of Florida, p. 122. 
Euprognatha^ characterized by an interantennular spine, which renders the 
rostrum trifid, an erect spine on the orbital arch, and the meros joint of the 
outer maxillipeds being somewhat L-shaped. E. rostellifera, Florida Straits, 
pp. 122 & 123. 
Amatkia modesta^ Sand Key, 120 fathoms, p. 124. 
Anomalopus [as AnomalipuSy preocc. in Coleopterd]. Carapace elongated, 
subcylindrical ; posterior pair of feet larger than penultimate; orbital arch but 
slightly distinct; postocular spine small. Type of new subfamily, Ano- 
malopinm [better Anomalopodinai\. A. furcillatusy Straits of Florida, 123 
fathoms, pp. 124 & 125.
