hurriedly to their particular hiding-places.” 
Many Geckos utter sounds, probably produced chiefly by a 
movement of the tongue against the palate, and in which “yecko,” 
“chucko,” “tockee,” or something similar, is distinctly audible. 
Sir Andrew Smith says that a South African Sand-Gecko (Pteno- 
pus garrulus) utters during the day a sharp sound somewhat like 
“chick, chick”; and he adds that the number thus occupied is at 
times so great, and the noise so disagreeable, as to cause the 
traveller to change his quarters. 
The plates with which this volume is illustrated have been 
carefully drawn by Messrs. Mintern and Smit, under the super- 
vision of Dr. Giinther, from whose preface we learn that this 
Catalogue may be expected to be completed in the course of next 
year, the manuscript of the second volume being far advanced.

rivers flow increases the charm and delight of fishing them. 
It seems therefore quite natural that one who has been a 
fisherman all his life, and attentive to Nature’s teaching, should 
sit down to place on record some of the many lessons he has 
learnt while following his favourite pursuit. 
In Dr. Hamilton’s lately published ‘ Recollections of Fly 
Fishing’ we have a very agreeable book of this kind, and although 
many such volumes have appeared, it cannot be said that this is 
a superfluous addition to the literature of Fishing. On the 
contrary, it strikes us that there is much that is fresh and original 
in his book, and if the subjects discussed therein are not always
