PALEONTOLOGY. 283 



Hills group. Two of them arc identical with Fox Hills s[)ecies. Lis- 

 iwdcsthes (?) haicorthi (u. sp.) is described aud tigiired (pp. 224-2U5). 

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

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

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

 They are — 



Cijrcna hrevidens. B. duhia. 



Corbicula Jnilisi. Fsammobia ohficura. 



C. rugeUnsis. Sant/uiuohria (?) caitdata. 



Jiatissa Newherryi. Teredo J'lujetenHis. 



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 groui^ with the Laramie. In another paper (28()) Mr. 

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

 iormations and considers the greater part of the Laramie as of Creta- 

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

 Cretaceous to the Tertiary period. 



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

 lieontology of the Mesozoic. 



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

 rocks of the Saskatchewan, is an appendix to Mr. J. B. Tyrrell's report, 

 and the following new species are described: 



Cyprina subtrapeziformis, p. 155e. 

 SolecurtuH (Tagelus) oceidentalls, p. 157c. 

 Marteria tumidifrons, pp. 157f-ir)H(;. 

 Ilydatina parvula, pp. loHe-ir/Jc. 

 Falwastacus (?) ornatus, pp. IGle-lG'ie. 



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. 1096, Triassic. 

 Celtiies (?) Fancouvereti,sis, p. 110/>, Triassic. 

 Placenticeras occldentale, p. 113ft, Cretaceous. 



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

 of British Columbia are described :
