438 Zoological Society : — 



The errata to be found in this book, especially in the lists of fos- 

 sils, are rather too numerous. We may remark, too, that Serpula, 

 Vermilia, and Lignite should not be classed under "Conchifera" 

 (p. 33), nor Pentacrinus, Serpula, Vermilia, Lignite, Selenite, and 

 Septaria be grouped as '• Mollusca " (p. 31) by a professed naturalist 

 like our author. 



Mr. Damon has conscientiously given references to his authorities ; 

 but a revision of the numerous references to what he terms M Geol. 

 Proc." would be desirable ; for he confuses together the ' Geol. Pro- 

 ceedings ' and the 'Geol. Journal,' and some are obviously in- 

 correct. 



It is a pity that the little map attached to this Handbook does 

 not indicate the geological structure of the district. The author, it 

 seems, expects his readers to have Sheet 17 of the Geological Survey 

 Map of Great Britain always in hand when they consult his book. 

 We would suggest that, in the next edition, Mr. Damon should add 

 an illustration, with a fuller account, of the curious "fault" of the 

 Ridgway, of which the railway makes a section at Upway. The 

 author might also draw attention to the great mass of stony material 

 in the Purbeck strata, due to the accumulation of multitudes of the 

 tiny shells of Cypridse — a fact of corresponding importance to the 

 existence of rocks made up of equally minute Foraminifera, which 

 he has noticed at pages 41 and 153. 



The woodcuts in this little work are of superior execution, both as 

 to drawing and engraving. The sections have evidently been pre- 

 pared by practised surveyors. The plates in the ' Supplement/ nine 

 in number, illustrative of Oolitic Fossils, have been drawn by one of 

 the best of English palseontographists, Mr. C. R. Bone, and are 

 elegant, truthful, and carefully finished. It is to be regretted that 

 this f Supplement ' is of a larger size than the f Handbook ' itself ; 

 for they ought to be bound together.

Description of a New Species of Manakin from North- 

 ern Brazil. By Philip Lutley Sclater, M.A., Secre- 

 tary to the Society. 



Our Corresponding Member, M. Jules Verreaux, of Paris, has 

 kindly sent to me for examination a specimen of a Manakin lately 

 received by one of his correspondents from Para, which seems to be- 

 long to a different species from any heretofore described. Its nearest 

 ally is certainly Pipra Jilicauda of Spix ; but it is readily distinguish- 

 able from *hat and every other member of the group, with which I 

 am acquainted, by the form of the tail-feathers. The outer rectrices 

 are acuminated and produced; the second, third, and succeeding 

 pairs in a less degree than the first ; the outer pair exceeding the
