ERRATA AND ADDENDA. 



Page 17, lines li and 15—0. The bones here described as coracoid and limb bones are, it now appears to me, more 

 likely to belong to the hyoid apparatus, as they somewhat resemble corresponding bones of Nccturus ; the 

 genus Ocstocophalus was therefore probably branchiferous. 

 " 21, 1. 5, for "bo found" read, belong to one of them. 



" 83, 1. 1, for " GXOCEPHAL.A" read GANOCEPPIALA. 

 " 87, 1. 17, for "caudals," read cervieals. 

 " 44, 1, 19, omit the word "form." 



44, under Elasmosaurus, Leidy having attempted to show that Klasmosaurus is the same as Discosaurus Leidy, 

 which should also include Cimoliasaurus L., 1 have controverted the positions assumed, in Silliman's Am. 

 Journ. Sci. Arts, 1870, 189-268. 

 " 48, 1. 13, for "anterior" read posterior. 



108, 1. 10. The discovery of the outer or shortest metatarsus confirms this moasurment ; its length is sixteen 



inches. 

 129, 1.9. For "strongly cmarginato," read "narrowed to an obtuse extremity." After this see appendix, 

 p. 232, where a third species, A. A.iilis, Cope, is added, and a paper in Proceedings A. Phil. Soc, 1870 

 (November), where A. SYNTHETICTJS, Cope, is described, with two new genera ZygohammA, Cope, and 

 lIoMOKOPiius. These are with Adocus erected into the family of Adocidw. The new species are Z. 

 stiuatula and II. insuettjs, Cope. 

 " 129. 1. 21, omit Pleurosteruum, Bell. 

 " 130, 1. 8. for " Pleurostcrnum " read Adocus. 



" 140, 22, the large specimen here described belongs to the O. platylomus. 

 " 137, 1.1. 4 — 11 — 13 — 10, for " cmarginatus " four times, read, platylomus. 

 " 143, line 21, for "223" read 2J. 

 " 151, 1. 7, for "widens" read wide as. 



" 100, 1. 1, for PTEROSAURIA read (?) RHYNCHOCEPHALIA. 

 " 180, 1. 15, omit all after "A structure somewhat resembling," &c. 



198, 1. 1. The vertebras described as pertaining to Mosasaurus brumbyi belong to another reptile, probably a 



Liodon, wdiich I have called L. porlatus. 

 208,1. 30. Add hero three species described in Proceed. Boston, Society Nat. History, Dec,., 1870, Ltodon 

 icteiuois, Cope, and Liodon mudget, Cope, from the Cretaceous chalk of Kansas, and L. dybpelob, 

 Cope, from New Mexico. 

 227, 1. 9. Add here two new species described with the above ; Cijdastes cineiuakum, Cope, and C. anti- 

 vai.idus, Cope, the latter figure in this volume, PI. V. fig. 5. 

 " 233, 1. 17, for "lines" read times ; for "mesosterna" read mcsosternal. 



" 233, 1. 41. Adocus vyomingensis does not belong to this genus, but to an allied form, Baptcmys of Leidy 

 and is probably of Tertiary age. Adocus proves to have an intergular scutum and be the type of a family 

 combining Cryptodire and Pleurodire characters. 

 " 239. The bird described as Meletujris superbus, 1 am informed by Prof. 0. C, Marsh, is the same as that 

 exhibited by him at a meeting of the Academy Natural Sciences, March 8th, 1870, (Proceedings p. 11) and 

 named MeUagril alius, Marsh. Of this fact I had no knowledge until after the above form had been 

 printed off, and now rely exclusively on Prof. Marsh's statement for the identification, as no description 

 accompanies the name, and I have not seen the types. As Prof. Marsh has priority of discovery and 

 determination, it is entirely proper that the species should hear his name, M. alius. 

 " 242, line from bottom, for "acquiescence to" read acquiescence in.
