REPORT OF NATIONAL MUSEUM, 1918. 



Springer, Frank. On the criuoid 

 genus Scyphocrinus and its bulbous 

 root Caniarocrinus. 



Smithsonian Inst. Pub. 

 No. 2440, 1917, pp. 

 1-74, pis. 1-9, figs. 

 1-19. 

 Monographic study of this in- 

 teresting and remarkable crinoid 

 genus, including descriptions 

 and illustrations of 8 species, 5 

 of which are new. The distribu- 

 tion and morphology of the 

 genus are described in detail, 

 and its relation to the bulbous 

 organism hitherto known as 

 Caniarocrinus is discussed fully. 

 The memoir also includes a sum- 

 mary of former work on the sub- 

 ject and a history of the discov- 

 ery and detailed description of 

 the magnificent specimen now 

 on exhibition in the National 

 Museum, upon which most of 

 the researches regarding the 

 morphology of the genus were 

 made.

 Fauna of the Mount Whyte forma- 

 tion. 



Smithsonian Misc. 

 Colls., 67, No. 3, 

 Sept. 26, 1917, pp. 

 61-114, pis. 8-13. 

 Descriptions of 30 species are 

 given, including 2 new genera 

 and 29 new species. The fauna, 

 which is Lower Cambrian, in- 

 cludes cystids, trilobites, brach-

iopods, and a phyllopod. The 

 new genera are Oogia, a cystid, 

 and Shafferia, a phyllopod. The 

 new species belong to the gen- 

 era Archacocyathus, Gogia, Mi- 

 cromitra, Obolus, Acrothele, Wi- 

 manella, Shafferia, Agraulos, 

 Olenopsis, Ptychoparia , Crepl- 

 cephalus, and Dorypyge. The 

 purpose of the investigation was 

 to establish the horizon of the 

 Mount Whyte formation, which 

 had been assigned to the Mid- 

 dle Cambrian by Burling in 

 1914 after Walcott had in 1908 

 referred it to the Lower Cam- 

 brian. The new fauna described 

 by Walcott fully supports his 

 claim, besides adding interest- 

 ing new sections, which will be 

 published with detailed descrip- 

 tions later on.

 from the Silurian formations of 

 Washington County, Me.

 20, 1917, pp. 27-58, 

 pis. 11, 12, 1 fig. 

 Synopses of 12 former arti- 

 cles are followed by a history of 

 the pelecypod genus Nuculites 

 and descriptions and illustra- 

 tions of 20 species from the 

 Silurian of Maine, 19 of which 

 are new. The article concludes 

 with remarks on the interpreta- 

 tion of fossils with special ref- 

 erence to species of Nuculites.

 The chemical industries of the 

 United States are notoriously 

 weak ; in fact, up to the out- 

 break of the present war there 

 were relatively few chemical in- 

 dustries, yet no field of indus- 

 trial activity is more essential 

 to the country. The most im- 

 portant of all the chemical in- 

 dustries is that represented in 

 the manufacture of coal prod- 

 ucts. The purpose of this paper 

 Is to bring out the reason for

the lack of the chemical indus- 

 tries in general and the coal 

 products one in particular, with 

 a view to determining where the 

 fault lies and what should be 

 done to correct it.

 The cost of fuel in the home 

 is roughly four or five times the 

 first cost at the mine. In other 

 words, the cost to the consumer 

 is out of all proportion to the 

 price at the producing end. 

 This discrepancy means an ex- 

 travagant price for fuel in the
