 genus of tubuliporoid bryozoa.

 No. 1797, Jan. 30, 1911, 

 pp. 497-527, figs. 1-27. 

 A study of the variation, dis- 

 tribution, and subdivisions of a 

 now generic bryozoan type, with 

 descriptions of all the known 

 forms — 16 species, 7 of which are

Bryozoa [of the Wisconsin De-

land, 1911, chap. 5, pp. 



49-67, pis. 5-11. 



Describes a bryozoan fauna of 



25 species from the Wisconsin De-

character between eastern and 



western North American faunas. 



The Waverlyan period of Ten- 



ee. 



Proe. U. S. Nat. Mus., 41, 

 No. 1851, June 24, 1911, 

 pp. 209-224. 

 A discussion of the early Missis- 

 sippian rocks of Tennessee for 

 which the term Waverlyan is em- 

 ployed. The new term, Ridgetop 

 shale, is proposed, the Tullahoma 

 formation is shown to be of Keo- 

 kuk age, and the New Providence 

 formation is recognized for the 

 first time in Tennessee as an em- 

 bayment deposit. This paper sup- 

 plements the one by Mr. Frank 

 Springer on the crinoid fauna of 

 the Knobstone formation.

Burling, Lancaster D. Photograph- 

 ing fossils by reflected light. 



Amer. Journ. Sci., 31, 1911, 

 pp. 99, 100, 1 fig. 

 Outlines a method whereby fos- 

 sils having no relief, but preserved 

 as a shiny film, may be photo- 

 graphed by direct reflected light 

 without distortion, both the ob- 

 ject and the photograph being ro- 

 tated through corresponding angles. 



Clark, Austin Hobart. The system- 

 atic position of the crinoid genus 

 Marsupites. 



Proc. U. S. Nat. Mus., 40, 

 No. 1845, June 24, 1911, 

 pp. 649-654. 

 The genus Marsupites, known 

 only as a fossil, is assigned to the 

 Comatulida ; the family Marsupi- 

 tidce, together with the family 

 Uintacrinidw, are placed in the 

 suborder Comatulida Innatantes, 

 the remaining comatulids being di- 

 vided into the 2 suborders Coma- 

 tulida Oliffophreata and Comatu- 

 lida Macrophreata. 



The unique calyx structure of 

 Marsupites is considered as the 

 result of its pelagic habits, which 

 are, for crinoids, very aberrant.
