Report of the State (Ieolovist. 329 



In the meantime, and for a large portion of the past year the 

 writer, with the aid of the regular assistant in Paleontology, 

 Prof. Clarke, and a special private assistant, Mr. Schuchert, lias 

 been occupied in bringing together and preparing material in 

 the way of collections; the general bibliography and the special 

 discussions upon the genera for the second part of volume VIII. 



As already stated, volume VIII, part i, has been put into type 

 to over 300 pages, and will be completed in about 350 pages 

 exclusive of index, which has been prepared as far as the printed 

 matter has been paged. 



Of the text of volume VIII, part ii, 207 manuscript pages have 

 been prepared. This is equivalent to about 125 pages of printed 

 matter. Nearly twice as much more will be required to complete 

 the discussions. In addition to the manuscript prepared, about 

 ninety pen-and-ink drawings for the text have been made to show 

 the structure of the spirals and loops, etc., in various genera. 



Volume VIII, part i, will contain forty-two lithographic plates, 

 numbered as follows : 



I. Inarticulata: I, II, III, IV, IVA, IVB, IVC, IVD, IVE, 

 IVF, IVG, IVH, IVK. 



II. Articulata: V, VA, VB, VC, VI, VIA, VII, VII A, VIII, 

 IX, IXA, X, XI, XIA, XIB, XIC, XII, XIII, XIV, XV, XV A, 

 XVB, XVI, XVII, XVIIA, XVIII, XIX, XX. 



With the exception of Plate XX, all have been printed, and 

 that one lithographed and proved. 



Of the plates to accompany part ii, the following have been 

 printed : XXI, XXII, XXIII, XXIV, XXV, XXVI, XXVII, 

 XXVIII, XXX, XXXI, XXXII, XXXIII, XXXIV, XXXV, 

 XXXVI. 



The following have been drawn on stone and proved : XXIX, 

 XXXVII, XXXVIII, XL, XLVIII, and the following are litho- 

 graphed but not yet proved : XLI, XLII, XLIII, XLIV, XLV, 

 XLVI, XLVII. 



The drawings on hand are sufficient to furnish the lithographer 

 with four plates, and a few additional drawings will be sufficient 

 to complete ten more. For the full illustration of the volume it 

 will require from twenty to twenty-five plates in addition to 

 these, and will necessitate the making of from 400 to 500 new 

 drawings.
