Description of Plate VIII. 



Holmia Kjerulfi Lnrs. Page 58. 



Fig. 1. (Nat. size). Somewhat incomplete specimen, but with most of segments 

 and pygidium preserved. Holmia shales, Tomten. Krist, 

 Univ. Pal. Mus. Cat. No. 13. XXVII. 296. 



Fig. 2 ( 3). Cranidium 3 mm. long, somewhat incomplete. A nepionic 



stage, about corresponding to fig. 2, pi. VII. From a wea- 

 thered calcareous sandstone bed, Holmia shales. Tomten. 

 Krist. Univ. Pal. Mus. Cat. No. 15. III. 2a. 



Fig. 3 (. : 3). Cranidium 2.5 mm. long, very incomplete. Later nepionic 

 stage. From a weathered calcareous sandstone bed, Holmia 

 shales, Tomten. Krist. Univ. Pal. Mus. Cat. No. 15. III. 2b. 



Fig. 4. (Nat. size). 2 specimens, one almost complete. They are somewhat 

 compressed from the side, although presumably one specimen 

 — to the left — was originally narrower and longer than 

 the other. Holmia shales, Tomten. Krist. Univ. Pal. Mus. 

 Cat. No. 13. XXVII. 616. 



Fig. 5. (Nat. size). Specimen with cranidium, the first segments and pygidium 

 in good state of preservation. Holmia shales, Tømten. -Krist. 

 Univ. Pal. Mus. Cat. No. 13. XXVII. 252. 



Fig.6. (Nat. size). The last eleven segments and pygidium. The last two seg- 

 ments without spines. Holmia shales, Tomten. Krist. Univ. 

 Pal. Mus. Cat. No. 13. XXVII. 352. 



Fig. 7. (Nat. size). Specimen with 14 segments preserved. Cranidium shows 

 doublure and hypostome attachment on left side. Holmia 

 shales, Tømten. Krist. Univ. Pal. Mus. Cat. No. 13. XXVII. 87. 



Fig. 8 (- 1.6). Pygidium and the three posterior segments. We notice 

 that the segment last but one has a faint spine. Holmia 

 shales, Tømten. Krist. Univ. Pal. Mus. Cat. No. 13. XXVII. 

 140. 



Fig. 9. (Nat. size). Cranidium and the 5 foremost segments. Cranidium is 

 almost unpressed, and the left eye is plastically preserved. 

 Krist. Univ. Pal. Mus. Cat. No. 13, XXVII. 107. 



Fig. lO.(Nat.size). The 15 foremost segments of a large and broad specimen. 

 Holmia shales, Tømten. Krist. Univ. Pal. Mus. Cat. No. 13. 

 XXVII. 295. 



Fig. 1 l.(Nat.size). Somewhat incomplete and highly compressed specimen. 

 Glabella more extended anteriorly than usual. The long 

 spines on 10 — 12 of the segments are seen to be well 

 preserved. The form of the thorax is unusually narrow 

 in proportion to the specimen depicted in fig. 10. Holmia 

 shales, Tømten. Krist. Univ. Pal. Mus. Cat. No. 13, XXVII.
