one little to wish for as regards a complete knowledge of these interest- 
ing species of the upper Olenus beds. 
The species described are Acerocare ecorite Ang., A. {Cyclognathus, 
Lin'rs.) mi'cropygum Lin'rs, A.norvegicum, n. sp. A. granulatum, n. sp. 
A.paradoximi, n. sp., A. tulbergi, n. sp., A. claudicans, n. sp., Para-

Dr. Pompeckj has made an exhaustive study of the genus Calym- 
mene, Brongn. He cites i"'. Schmidt as having divided the genus into 
three sections, i. Calymmene, sens strict., with the type C. tuberculata 
Dal?n (= blumenbachi), 2. PharostomaCord^., Type, C.pulchra Barr., 
and 3. Ptychometopiis, F. Schmidt. The author supports Brogger in 
considering Calymenopsis, Bergeron, as superfluous, C. fillacovi being a 
variety of Eiilorna oniatum Ang. 
Dr. Pompeckj proposes an arrangement of the forms referred to Cal- 
ymmene somewhat different from F. Schmidt's. He would divide the 
genus into two main sections ; the first (A; containing the groups (i) 
Pharostoma Corda, and (2) Calymmene, s. strict., F. Schmidt. Both of 
these Pompeckj would include under Calymmene proper. The second 
section (B) to contain the groups of (3) C. tristani Brong. (4) of C. arago 
Row., and (5) of Ptychometopus, F. Schmidt. This section Pompeckj 
calls Synhomalonotus. 
Freeh considers Euloma, Angelin, as the stem genus of Pharostoma, 
but Pompeckj regards Bavarilla of Barrande as holding this place. He 
looks to Neseuretus, Hicks, as the source of the B section, and he re- 
gards Homalonotus also as having sprung from this source (page 248). 
Should not Section B then be referred to Homalonotus rather than Cal- 
ymmene? G. F. M. 
The Special Report on Kansas Coal. Erasmus Haworth; W. R. 
Crane. (Univ. Geol. Sur. Kansas, vol. HI, 347 pp., Topeka, 1898.) 
The third volume of geological notes, that has been recently is- 
sued under the auspices of the University of Kansas, presents much 
interesting information regarding the sunflower state. It purports to 
be a special report on the coals. As a whole it gives us our first 
connected review of the Kansas Carboniferous below the so-called Per- 
mian. 
When it is remembered that this work is done 'argely without 
financial compensation, too much credit cannot be bestowed upon 
the Kansas geologists who have thus so generously given their serv- 
ices to their State. It behooves the great State of Kansas, so rich 
in mineral wealth, to be equal to the occasion and aid this most 
worthy undertaking in a manner more befitting her already exalted 
position. Professor Haworth, speaking not of his own labors but of 
those who have rendered him assistance says that the greater part
