Revieio of Recent Geological Literature. 355 
and clearly presented treatise on the growing science of meteorology is 
written with reference both to use in the class-room and for general 
readers. It contains the recent important additions to the theoretic ex- 
planations of the atmospheric circulation and production of storms 
which were studied out by the late Prof. William Ferrel, of Washing- 
ton; and the author also acknowledges his greal indebtedness to KUma- 
tologie and other writings by Prof. Julius Hann, of Vienna. Looking 
over the admirable work which Prof. Davis has done in this volume 
and his many geological papers, especially those relating to the glacial 
drift, we cannot refrain from earnestly hopinii' that he may next com- 
bine these investigations in treating of the climates of the tee age and 
earlier geologic ages. 
Crinoidea of Gotland. l>y F. A. Bather. Kongl. Svenska Vetenskaps- 
Akademiens Handlingar. Hand 25, No. 2, 200 pp., Id plates. Stock- 
holm, 1893. Paleontologists have long admired the crinoids found in the 
Silurian rocks of Gotland; but ever since the publication of Angelin's 
beautiful "Iconographia Crinoideorum," some fifteen years ago, the 
Swedish fossils have greatly puzzled students of crinoid morphology. 
The marvelous structures and curious combinations pictured in I hi' 
Iconographia disclosed difficulties which were insuperable to the anat- 
omist. Although the figures are so artistic and so perfect as to cause 
a suspicion to linger in one's mind that many may be to some extent 
restorations, it was with considerable astonishment that workers in 
general learned recently that many of Angelin's illustrations were mere 
combinations and composites, in some cases made up of several individ- 
uals and in other instances of even different species. 
The chief purpose of Mr. Bather's timely paper is to discuss the Got- 
land crinoids in the light of recent morphological prpgress and to set 
aright many of the erroneous ideas promulgated by the Swedish author. 
This has been all the more important on account of the (dose relations 
existing between the Silurian crinoidal fauna of England and that of 
Sweden. It was upon British fossil crinoids that Mr. Bather first began 
to study, but it was soon found necessary to lake up the related, and in 
part identical, species from the continent before working up the home 
collections. 
The portion of the work just issued is Part I. I he ( 'ri no idea I n ad una la. 
These are taken up first, because, as the author says, they ina\ be very 
plausibly regarded as the simplest forms of crinoids and as least re- 
moved from the type whence all families of crinoids have sprung. 
In Gotland the Inadunata are represented by at least fortj species, 
which are described in the paper, and probably by a few other species 
still doubtful, which have been set aside for the present in the hope of 
better material coming to light. Of the Forty species considered, eigh- 
teen were founded by Angelin, sixteen are regarded as new. and the 
rest were previously described by other authors. These species are re- 
ferred to ten genera, of which Gothocrinus is regarded as new. and one. 
Ilomocrinus, has not been hitherto recorded from Europe. These
