4. On a collection of Crustacea from Virginia, North Caro-
lina, and Florida, with a revision of the genera of Crangonide
and Paleemonide ; by J. 8. Kinestey. (From Proc. Acad. Nat.
Sci. Phila. for 1879, pp. 383-427, pl. 14. No date: received
March, 1880).—This, the longest of Mr. Kingsley’s papers on
American crustacea, notices about 100 species (9 of which are
described as new), and is the most complete list yet published of
the crustacea of the coast of the Southern States. It is based
upon collections made by Prof. Webster of Union College. De-
capoda only are included and of these the Pagurioidea are omitted.
The paper covers partially the same ground as Mr Kingsley’s
“List of the Decapod Crustacea of the Atlantic coast, whose
range includes Fort Macon” (op. cit., 1878, pp. 316-330), and is
a marked improvement upon it. Attention should be called,
however, to a few of the mistakes noticed in a cursory examina-
tion. In extending the range of Leptopodia sagitiaria to Chili
on the authority of A. Milne Edwards’ identification of LZ. debilis

424

with that species, the author overlooks Milne Edwards’ statement
in the same paragraph that L. sagittaria Kdwards and Lucas is
a distinct species for which the name modesta is proposed. Acta
spinifera (sp. nov.) appears to be A. acantha A. Milne Edwards,
which has been well figured twice; and if not Milne Edwards?
species it should have been compared with it rather than with A.
hirsutissima. Hupilumnus Websteri (gen. et sp. nov.), figured
and very briefly described from a single specimen wanting the
chelipeds, is evidently not very closely allied to Pihumnus and is
apparently based on a young specimen of Domacea hispida, which
had already been reported from the Florida reefs by Stimpson.
Moreover, the name Hupilumnus is preoccupied, having been used
(according to the Zaological Record for 1877) by Kossmann for
a division of the old genus Pilumnus. In attempting, in a foot-
note on p. 405, to “straighten the synonymy of two species of
Petrolisthes,” the confusion in the synonymy of one of the species
isinereased. Petrolisthes Helleri is proposed for Porcellana Dane
Heller (non Gibbes), regarded by Heller as the same as Porcel.
armata Dana (non Gibbes). Dana, however, discovered that
his name armata was preoccupied and, in the appendix to his
great work, p. 1593, and in the explanation to the plates, substi-
tuted spinuligera for bis species, though this has been overlooked
by Stimpson and Heller as well as by Kingsley. The reason for
the reference of the species to Petrolisthes is not apparent, for
Stimpson retained Dana’s species in the restricted genus Porcel-
lana and, at least, it has no appearance of being a /etrolisthes.

Under Caridea there is a useful revision of the genera of Cran-
gonide, Atyide, and Palemonide, though one is occasionally left
in doubt as to the limits of the genera adopted; as in the case of
the first genus, Orangon,which is said to include Steiracrangon
Kinahan, while no mention whatever is made of the same author’s
Cheraphilus, which has recently been adopted by G. O. Sars and
by Miers. A peculiar misuse of “ibid.”, which the proof-reader
ought to have corrected, might be overlooked did it not recur so
persistently in nearly all of Mr. Kingsley’s papers. ss. 1. SMITH.

5. The Crayfish: an Introduction to the Study of Zoology ;
by T. H. Huxtry. 371 pp. 8vo. New York, 1880 (D. Appleton
& Co.)—This last volume of the Iuternational Scientific Series is
far more interesting than ordinary text-books of zoology and well-
deserving of careful study. Though it treats specially of the natural
history, physiology, morphology, comparative morphology, dis-
tribution, and origin of crayfishes, 1t admirably fulfills the author’s
desire, as "expressed in the preface, “to show how the careful study
of one of the commonest and most insignificant of animals, leads
us, step by step, from every-day knowledge to the widest general-
izations and the most difficult problems of zoology.” <A large
part of the excellent wood-cut illustrations are new, and many are
unusually beautiful for a work of this class. The figures (after
Bate) on page 282, are of Carcinus menas, not Cancer pagurus
as labeled. S. I. SMITH.
