tites resembling a Portage species, Pleurotomaria cf. P. sidcomar- 

 ginata. The names marked with an asterisk are Hamilton spe- 

 cies, or near them. The Trilobite tribe has its species through the 

 series instead of being; absent as in the Chemung and Catskill of 

 New York. 



3. Saccamina Friana (Communicated). — I observe that 

 this little fossil has again come under the notice of naturalists.* 

 When specimens from Sandusky were kindly sent to me some 

 years ago by my friend Dr. Newberry, I was, as a paleontologist, 

 naturally disposed to refer them to Characece, but a comparison 

 with specimens from the French Tertiaries convinced me that 

 this was untenable, and as I found that in form and texture, 

 though not in material, the fossil corresponded to the well-known 

 Saccamina of the Carboniferous, I placed it provisionally in 

 that genus.f Subsequently, and apparently without knowing- 

 what I had done, ITlrich ("Contributions," Yol. I, 1S8G), de- 

 scribed the Ohio Falls specimens, and referred them to Forami- 

 nifera as I had done, but with the new name Modlerina Greenei. 

 I may say that I still hold to my original opinion that these 

 organisms are foraminiferal tests, for the reasons fully stated in 

 my paper in the Canadian Naturalist, 1883, and which I think 

 have not yet been controverted. 



I have no other objection to Dr. Williamson's name, Calci- 

 sp/uera, except that it seems certain that the organisms from 

 Kelley's Island are of entirely different nature from those from 

 Wales, and therefore should not bear the same name. I also con- 

 sider it probable that the specimens described by Ulrich are 

 specifically distinct, though it is not unlikely that the double 

 wall described by him may be a result of difference of preserva- 

 tion rather than original structure. In my specimens the Avail 

 seem continuous and granular, having in fact a similar structure 

 to that of other fossil Foraminifera whose tests are composed of 

 calcareous grains. My specimens show some indications that the 

 test was finely porous. This caused me to suggest a possible 

 affinity with Lagenidce, which I find Ulrich also suggests.

 — In this valuable paper Dr. Roemer describes with his usual 

 skill, a most interesting fauna from Barton's creek, a few miles 

 west of the city of Austin. The descriptions are excellent and 

 the figures beautiful. Twenty-one species are figured and de- 

 scribed, of which eighteen are alleged to be new. As the re- 

 viewer has made a special study of the faunal and stratigraphic 

 horizons of these fossils, he would here correct one or two mis- 

 takes in the otherwise excellent publication. Instead of being
