forty years of the eighteenth century. Further interest will be found 

 in the names of and notes on the numerous geologists, both British 

 and foreign, who were admitted as guests to the dinners, with the 

 curious un-British arrangement that they had to pay for their 

 own food. 



The book demanded wide knowledge and reading, and thei'e are 

 but few slips. Huxley died in 1895, Carpenter (p. 402) was W. B., 

 and Horsley died in Mesopotamia. The statements on p. 428 are 

 unfortunate.

1. — A. Contribution to the Invertebrate Fauna of the Oligocene 

 Beds of Flint Kiver, Georgia. By William Healey Dall. 

 Proc. United States Nat. Mus., vol. li, pp. 487-524, with 

 pis. lxxxiii-viii, 1916. 



IN this work the author recognizes two zones, an upper and a lower. 

 The former has yielded 61 species, of which 29 are new, while 

 the lower zone has furnished 39 species, among which 9 are new. 

 Five of the new species and 14 of the others are said to be common 

 to both zones. A useful distribution table is given of the fauna 

 showing the occurrences of the various species in both zones and 

 their presence in the Ocala, Yicksburg, Orthaulax, and Chipola 

 horizons. The fauna described is entirely molluscan, comprising 

 Pelecypoda, Gasteropoda, and Scaphopoda. 



2. MoLLUSKS FROM THE TYPE LOCALITY OF THE ChOCTAWHATCHEE 



Marl. By Wendell C. Mansfield. Proc. United States Nat. 



Mus., vol. li, pp. 599-607, pi. cxiii, 1916. 

 1 HUE fauna here described is made up of Pelecypoda, Gastropoda, 

 JL and Scaphopoda, having been collected in the Choctawhatchee 

 Marl, regarded as of Miocene age, occurring near Redbay, Walton 

 County, Florida. Descriptions and illustrations are given of the 

 following new species of Pelecypoda : Area (Scapharca) staminea, 

 Say, new sub-species rubisiniana, Leda choctaivhatcheiinsis, Phacoides 

 {Pleurolucina) choctaivhatcheensis, Astarte (Asktarotha) Vaughani, and 

 Biplodonta ivaltonensis. The complete fauna of this deposit is tabu- 

 lated so that the range of the species is shown from Oligocene to 

 Pliocene times. 



3. — The Shells of the Holderness Basement Clays. By Alfred 



Bell. The Naturalist, 1917, pp. 95-8, 135-8. 

 rpHIS paper furnishes a revision of the published lists of Mollusca 

 J_ from these deposits, with criticisms and remarks on the 

 determinations and nomenclature. Of the 180 molluscs recorded, it 

 is stated that at least 100 are no longer living south of the Shetlands, 

 while the remainder mostly belong to Arctic Norway. Relationships 

 of the Mollusca are noticeable in the Bridlington and Chillesford 

 Beds.
