The issues year by year of the Transactions of the Hull 

 Scientific and Field Naturalists' Club have been timely, able, 

 and well up to date. The work of the club in its Field depart- 

 ment has been most persevering, and during a long series of 

 years excellent work has been done. The results of these 

 labours and a series of papers on East Riding topics have been 

 issued from time to time under the able editorship of Mr. 

 Sheppard. Vol. II., 'The Flora of the East Riding,' by 

 Mr. J. F. Robinson, is now a standard work on the distribution 

 of the Flora in that Riding, and will be the basis of all future 

 work. We have here a similar and much wanted work on

 of the various areas has been done by members of the Yorkshire 

 Naturalists' Union and the Hull Club. The tables are excellent 

 and the summary of results is suggestive. The monograph 

 also directly and indirectly calls attention not only to what has 

 been done but also what still waits to be accomplished ; for 

 example, the northern and central portions of Derwentland have 

 been practically unworked, and final conclusions as to the fauna 

 of that part of the district cannot be come to. The same applies 

 to the central northern parts of the Wolds section, especially 

 the northern and western slopes. Within the last year special 

 attention has been given to the neighbourhood of Tibthorpe-on- 

 the-Wolds, with results that have far exceeded all expectations.
