PALEONTOLOGY. 283 



Hills group. Two of them are ideutical with Fox Hills species. lAs- 

 podesthes (?) haworthi (u. sp.) is described and figured (pp. 22'4-225). 

 Another paper (287) discusses the Puget group of Washington Terri- 

 toTj. Twelve species are recognized from these rocks, eight of which 

 are regarded as new, and are named but not described. 

 They are — 



Cyrena hrevldens. B. duhia. 



Corhicula WUlisi. rsamniohia ohscura. 



C. Pugeiensis. Sanyuinolana (?) caudata. 



Batissa Newherryi. Teredo Pugetensis. 



Study of the fossils leads the author to agree with J. S. Newberry 

 and Bailey Willis as to the equivalency and probable contemporaneity 

 of the Puget group with the Laramie. In another paper (286) Mr. 

 White discusses the relation of the Laramie group to other and later 

 formations and considers the greater jDart of the Laramie as of Creta- 

 ceous age, the upper strata representing a gradual transition from the 

 Cretaceous to the Tertiary period. 



J. F. Whitea\ es (292, 294, 295) contributes three papers on the Pa- 

 Ireontology of the Mesozoic. 



The first (295), on some fossils from the Cretaceous and Laramie 

 rocks of the Saskatchewan, is an appendi:^; to Mr. J. B.TyrrelPs report, 

 and the following new species are described: 



Cyprina suhtrapeziformis, p. 155e. 

 Solecurtus {Tagehts) occldentalis, p. 157e. 

 Marteria lumidifrons, pp. 157e-158e. 

 Hydatina parvnla, pp. 158e-1.59e. 

 Palwastacua (?) ornatus, pp. 161e-162e. 



In the second paper (294), which is an appendix to G. M. Dawson's 

 report, some Mesozoic fossils from British Columbia are described. 

 The new species are as follows : 



Aulacoceras Charlottense, p. 109&, Triassio. 

 Celiites (?) Fancouvereiisls, p. 1106, Triiissic. 

 Placenticeras oceidentale, p. Il3h, Cretaceous. 



In the third paper (292) the following new species from the Triassio 

 of British Columbia are described: 



Spiriferina iorealia, p. 128, pi. 17, f. 1. 

 Terebratnla Liardensis, p. 130, pi. 17, f. 2, 2a, 2h, 2c.
