As to the animal itself, it is well The smaller and more pointed 



characterized by the white colour anterior limbs, the dark-coloured 



of the upper lip, by the large size upper lip, and the distinct and 



and breadth of the anterior limbs, clearly detiued light lateral band 



and the faint indication or total well characterize this species, 

 absence of the whitish band or 

 spots. 



I do not attempt to contribute anything towards the know- 

 ledge of tlie exotic species of the same genus, which, in general, 

 seem capable of being referred to the two preceding types, 

 but the relations of which to the northern species have not yet 

 been submitted to a critical examination ; but I will never- 

 theless remark that the late Prof. Malm, in a memoir which 

 has unfortunately escaped the notice of Prof. Flower, has 

 recorded a Lagenorhynchus dancuhis, captured at Cape Horn, 

 the skeleton of which contains only seventy-one vertebrae. 

 It is therefore without doubt a distinct species from L. albi- 

 rostrisy and the diagnosis of the genus, so far as the number 

 of vertebraj is concerned, must in consequence be modified. 

 Nor will it be superHuous to remark that the genus Lageno- 

 rhynchus must be ranged in that division of the Odontoceti 

 (the true Dolphins) to which belong the genera Delphiiiusy 

 Frode/phinus, Steno, Tursio])s, and Sotalia^ and which is 

 distinguished by the character of having the beak plainly 

 separated from the frontal convexity.

The Flora of West YorJishire, ivith a Sketch of the ClimatoJoyij and 

 Litholoyij in connection therewith. By Frederic Arnold Lees. 

 8vo. Tp. 843, with Map. London : Lovell Ecevc and Co., 



1888. 



A VOLUME of 8-43 pages with the numberless facts that a Flora of a 

 large district implies is a difficult subject to compress into a short 

 notice, especially when there are matters touched on in this work 

 that a student of our Flora from its distribution-point would be 

 tempted to be too discursive on. 



The author dedicates his book to the late Rev. W. W. Newbould, 

 and a better dedication could not be, for to lew men are given the 

 pow er of unselfish help that he possessed. 



Due peculiarity of (his Flora may well be mentioned; the author
