PI. C, Fig. 15. 

 lulus telluster Scuiider, Bull. U. S. Geol. Surv. Terr., vol. 4, 1878, p. 776. 



The single specimen is so fragmentary that it can only be referred to 

 lulus in a broad generic sense. The piece is composed of ten or twelve 

 segments, probably from near the middle of the body, lying in a straight 

 line and crushed, with no trace of any appendages. The segments appear 

 to be composed of a short anterior and a larger posterior division, oa <-h 

 independently and very slightly arched ; the posterior division is about 

 twice as long as the anterior, and each is transversely, regularly, and very 

 finely striatc, parallel to the anterior and posterior margins of the segments. 

 The foramina can be detected on some of the segments, and by their aid 

 the width of the body can be more accurately determined. 



As crushed, the body is 2.3' um broad, but its probable true width is 

 1.5""", while the segments are each about 0.8 mm long; the fragment pre- 

 served measures 8.5 Dlm long. 



Green River, Wyoming, one specimen, No. 154, F. C. A. Richardson. 



The object represented on PI. 12, Fig. 1, was at one time thought to 

 be a myriapod and accordingly figured, but examination proved it to be the 

 broken section of the cone of Sequoia, not uncommonly found at Florissant.
