BIBLIOGRAPHICAL NOTICES. 



Fasciculi Malayensis : Zoology. Part II. 1903. 

 Longmans, Green, & Co. 



The value of the work accomplished by Messrs. Annandale and 

 Eobinson during their expedition to Perak and the Siamese Malay 

 States in 1903-2 may be measured by the admirable series of 

 memoirs thereon which are now passing through the press. 



The second part, dealing with the zoological results of the ex- 

 pedition, embraces papers on the non-operculate MoUusca ; Rhyn- 

 chota ; Coleoptera ; and the structure and mechanism of the funnel 

 surrounding the mouth of the tadpole of Megalophrys montana ; 

 Marine and Freshwater Fishes ; and a tooth of Elejihas namadicvs. 



The bulk of these papers are of a purely technical character. The 

 most interesting perhaps is that on the marine fishes, inasmuch as 

 it embraces some curious facts concerning the justly celebrated 

 " walking-fishes," PeriophtJiahnus and BoUophthalnius. 



A newly discovered species of the first-named genus, P. pliya, 

 proves to be remarkable in more ways than one, but chiefly on 

 account of the fact that it constructs a more or less permanent 

 burrow, used either as a refuge when threatened or as a shelter in 

 bad weather ; it may possibly also serve as a nest, but about this 

 there is some doubt. 



The main entrance to this burrow lies in a pool of water, which 

 is maintained when the tide sinks (for it is always made between 

 tide-marks) by a rampart of mud some 5 or 6 inches high and a 

 foot and a half in diameter. Outside this rampart a number of 

 small holes are always found, and these lead into the central shaft. 

 When alarmed the fishes dive at once into one of the outer shafts 

 or else mount the rampart, and after a careful survey either pitch 

 headloug into the central pool or resume their hunting. 



It would have been well if more accounts of this kind had been 

 included in the volume; as a rule, however, little more than a list 

 of species of each of the groups collected has been given. 



The two coloured plates of Rhynchota certainly represent the 

 acme of the three-colour process and are really splendidly rendered. 



The third part of this volume will, we believe, be published 

 shortly.

The papers on Mammalia which have been published in the 

 columns of the ' Annals ' during the last few years are alone 

 sufficient to serve as an indication of the great progress which has 

 been made in the detailed study of that group, and the numerous 

 changes in nomenclature which have been advocated, during the 

 period in question. Any systematic work on Mammals published
