described, but not figured. The Survey, however, proposes to 

 publish a monograph of the Silurian Polyzoa before long. Mr. 

 TJlrich also contributes a paper on Crinoidea, and describes three new 

 genera, Cremacrinus, Deltacrinus, and Halysiocrinus (pp. 104-113). 

 The list of specimens acquired by the Museum in 1885 fills ten 

 pages, and shows, we should imagine, a very satisfactory state of 

 things. Some new fossils are described at pp. 313-318 (pi. i. and 

 ii.), by Prof. Winchell, one of them being a specimen of the peculiar 

 form, Cryptozoon, described recently hj Prof. James Hall. Mr. 

 Winchell also writes upon a peculiar ore and the Cambrian rocks of 

 the State of Minnesota (pp. 319-337). The most bulky contribution 

 to this Eeport is " The Bibliography of the Foraminifera," by Prof. 

 Anthony "Woodward (pp. 167-312). His work having been antici- 

 pated by Mr. H. B. Brady's bibliography in the " Challenger " Report, 

 so well known to workers on the subject. Prof. Woodward has 

 rearranged the results of his own work with the materials of the 

 published list, and has given it in alphabetical order in groups under 

 countries. His work, though, as he truly says, incomplete, is useful ; 

 but unfortunately it is marred by very numerous typographical and 

 bibliographic errors. The page and a half of errata for the list stop 

 hopelessly at seventy pages from its end. Such errors as occur un- 

 noticed in the references will prove serious hindrances to the utility 

 of his work. Instances taken at random, — such as duplicate entries 

 and wrong dates given with Dawson, at p. 180; with Jones at pp. 

 184 and 202, and with Ehrenberg at pp. 193 and 194; errors at 

 p. 271, " Bisherigebnisseder Tiefbohrung," etc. ; p. 252, Tregnem ; 

 p. 245, Milne-Ewards ; p. 286, Summersetshire, etc., make the reader 

 regret that so useful a work should have been printed without 

 correction. Eozoon has a separate bibliography ; and Becepiaculites 

 is included in the general list. 



Besides a few pages of matter relating to geological and chemical 

 research not mentioned above, there is Mr. 0. W. Oestlund's " List 

 of the Aphididee of Minnesota, with descriptions of some new 

 species" (pp. 17-56), unfortunately without figures; also Concho- 

 logical Notes, by U. S. Grant (pp. 114-124). T. E. J. 



IV. — Physical Geology of West British Garwhal, with Notes 

 ON A Route Traverse through Jaunsar Bawar, and Tiri- 

 Garwhal. By C. S. Middlemiss, B.A. Records of the Geologi- 

 cal Survey of India, vol. xx. Part i. 1887, pp. 26-40, with 2 

 maps and plates of sections. 



THE second and most important part of this memoir deals with 

 the geological structure of a tract situated 120 miles N.E. of 

 Delhi, and bordered on the N. and S. by the Sub-Himalayan boundary 

 and the Nyar river, and E. and W. by the Ganges at Hardwar and 

 Ghungti mountain. It is illustrated by a small-scale map of the 

 whole area and its N.W. corner by one on the one-inch scale. In the 

 district are found Tertiary strata (Nummulitic and Sub-Himalayan), 

 Mesozoic grits and impure limestones, both fossiliferous ; massive 

 nnfossiliferous limestones, purple slates and volcanic breccia, and
