the Scotch and Irish Hare is well shown, and Natterer's Bat in Part iii. 

 is a well designed picture of light and shade, but there is, perhaps, too 

 much colour in the plates of the Dormouse and the Noctule. Part iv. 

 ends with the Long-eared Bat, the letterpress of which is still unfinished. 



The work on the eight species of Chiroptera, already dealt with, is 

 described by a well-known natui^alist as " splendid." The author has 

 largely drawn on the contributions of Irishmen — Kinahan, Alcock, &c. — 

 and in a conspicuous degree from the careful and suggestive observations 

 of Moffat, whose papers on the habits of our native bats are a remarkable 

 tribute to his patience and ingenuitj\ 



The labour bestowed by the author has been immense and the 

 authorities are quoted with scrupulous care. Only two or three slips 

 have been noticed. On page 30 of the Introduction, Rockabill is 

 given as a light-station on the nest coast of Ireland. In the table of 

 dimensions, page 87, of Leisler's Bat, a specimen in the Dviblin Museum 

 from Co. Clare is referred to, whereas Clare is not given as an Irish 

 locality on page 85, when dealing with the distribution of this species. 

 On page 197, Charbonnier is given as the authority (the only one) for 

 the weight, 5 grams (78 grains), of the Long-eared Bat. This must have 

 been an abnormally light specimen as Moffat {Irish Natttralist, 1900, 

 page 235) gives the weight as ranging from 100 to 130 grains. 



Naturalists owe a debt of gratitude to the author for his courageous 

 and successful effort to publish at immense labour a work, which, if 

 completed on the same lines as the four parts issued, will remain for years- 

 without a rival as the standard authority on British Mammals.

A CENSUS OF IRISH CRYPTOGAMS. 



BY J. ADAMS, M.A. 



A SHORT statistical summary of the number of species 

 belonging to each of the great groups of ilowerless plants 

 found in Ireland, and of our present knowledge of their 

 distribution up to the end of the year 1910, will, I think, 

 be of interest to Irish botanists. A few years ago such a 

 summary would not have been possible. However, the 

 publication by the Royal Irish Academy during the years 

 1908, 1909, and 1910 of detailed lists of species of Algae, 

 Lichens, and Fungi found in Ireland, together with the 

 additions to each of these groups up to the end of the year 

 1910 enumerated in the pages of the Irish Naturalist for 

 April, 1911, makes the task a comparatively light one in 

 the case of the lower Cryptogams. As regards Liverworts
