1. In Mr. Binney 's contribution will be found, besides introductory 

 remarks, the bibliographical history and general observations upon 

 Lepidodendrcn and Halonia, together with descriptions and figures 

 of specimens referred to Lepidodendron Harcourtii, Sigillaria vascu- 

 laris, and Halonia regularis. None of these species are new to 

 science ; but the plates, prepared, for the most part, from exquisite 

 sections, showing the microscopic structure, are drawn with extreme 

 skill by Mr. J. N. Fitch, of the Eoyal Botanic Gardens, Kew, and 

 well maintain the admirable character of the author's monograph. 



2. Mr. Woodward contributes another portion of the History of the 

 Merostomata, which is to be completed in the 4th part, now in the press. 



It includes Pterygotus raniceps from Lanarkshire, seven species 

 from the neighbourhood of Ludlow, Kington, etc., given on the 

 authority of Mr. J. W. Salter, and a full account of Slimonia acumi- 

 nata, one of the most perfect forms yet discovered in the Upper 

 Silurian of Lesmahagow. A nearly entire example of this species, 

 measuring 26-| inches, figured of the natural size, forms the subject 

 of one of the plates (pi. xvii.). An outline restoration of Slimonia is 

 also given on pL xx. 



3. Mr. Wood's suj)plement to the Crag Mollusca,* which treats 

 only of the Gasteropoda and one Pteropod, is preceded by an 

 interesting notice of 28 pages, by his son and Mr. Harmer, on the 

 Geology of the Upper Tertiaries of East Anglia, accompanied by a 

 map and sections, the result of their labours in the Eastern Counties 

 for several years past, and including the Coralline and Eed Crags, 

 the Chillesford Beds, the Forest Beds, the ' Lower,' ' Middle,' and 

 'Great' Chalky Clay, or 'Upper' Glacial series, together with remarks 

 vipoii the so-called Plateau-gravel and Post-Glacial formations. 



In a monograph on Crag Mollusca, the addition of a sketch of the 

 geological relations of the several formations enhances greatly the 

 value of the work as showing the true geological sequence of the 



' Mr. "Wood's Oris:inal Monograph on the Crag Mollusca appeared in 1847, and 

 formed the first publication of this Society.
