B G. HOLM AND A. H, WE8TEEGAAKD 



Among the papers Holm left no text or notes concerning this fauna were found, not 

 even complete explanations of the printed plates, but only preliminary generic and specific 

 references to some of the forms reproduced, which may be quoted here : 



Anomocare excavatum (Aug.), pi. II, fig. 1 — 5, 8 — 14. 



Anomocare limbatum (Ang.), pi. II, tig. 15 — 20; pi. Ill, fig. 1 — 2. 



Anomocare sp., pi. Ill, fig. 9. 



Paradoxides sp., pi. Ill, fig. 13 — 14, 16, 5. 



Agnostus glandiformis Ang., pi. I, fig. 2 — 4. 



Agnostus nudus (Beye.), pi. I, fig. 6 — 9, 11 — 12. 



Agnostus aff. hituherculatus Brogg. (non Ang.), pi. I, fig. 1 3. 



Agnostus aff. kjerulft Beogg., pi. I, fig. 27 — 30. 



Agnostus sp., pi. I, fig. 14 — 23. 



Acrotreta sp., pi. Ill, fig. 34 — 36. 



Lingula sp., pi. Ill, fig. 31 — 33. 



Consequently, I alone am responsible for the text of this paper, which may be em- 

 phasized in order that Holm may not bear the responsibility for opinions with which he 

 might possibly have in part disagreed. . 



As the printed plates were not of size suitable for these Memoires, I had to arrange 

 the figures for new plates to be reprinted in Leningrad. Previous to that a couple of the 

 figures — pencil drawings by Liljevall^ — were to some extent amended, and eighteen 

 figures — retouched photographs of better preserved specimens from the collection received 

 in 1928 — were added. This work was done by Mr. J. W. England. 



Finally I wish to emphasize that I have had in view only the identification of the 

 fossils under consideration so far as the material has made it possible, in order to fix the 

 geological age of the strata and their relations to contemporary deposits of other regions. 

 Thus, in this paper, I still use the generic references hitherto in use, though a revision 

 in several cases, e. g. in the case of the Agnostidae, would have been desirable. I am at 

 present working on such a revision, along with a revision of the fauna and sequence of the 

 Middle Cambrian of Sweden, a work which, however, is far from completion and whicli it 

 would be premature refer here.
