interest. The first collection comprises three males and five 

 females. The males hardly differ from some New Guinea males, 

 on the under side of the hind-wing they have scarcely any 

 markings, except the orange anal spot. Four of the females 

 belong to the white amanga form ; ihey are variable in their 

 markings, and, on the whole, of a purer white than any I have 

 from New Guinea. The remaining female (Rothschild's so-called 

 " typical " female) is marked somewhat as in the male, but has a 

 complete series of subterminal spots on the hind-wing above and 

 below, and the smaller white central area of hind-wing is repre- 

 sented below. The second collection contains seven males and 

 five females. The males are very similar to those of the first 

 coUecUon except one specimen, which has the whitish discal 

 scales of hind-wing below better developed. Four of the females 

 are white amanga forms, very variable as usual, with the light 

 area of the fore-wings in three of the specimens very much 

 reduced. The fifth specimen is also of the so-called " typical " 

 form, and only differs from the single specimen of this form in 

 first collection in having the white central area of hind-wing 



larger. 



The absence of the polijdorinus form of female, and the 

 predominance of the while amanga form of female, should be 

 noted. It is probable that the white atnanga form is much 

 commoner on the islands surrounding New Guinea than upon the 

 mainland itself. 



We have received the first number oiThe Microscope, a monthly 

 journal edited and published by Messrs. H. and F. Baker, 78 

 Swanston-street, Melbourne. It is brightly wTitten, and will, no 

 doubt, assist in the advancement of microscopical science. The 

 subscription rate is 3s. 6d. per annum, post free. 



Frogs. — Among my exhibits at the recent conversazione were 

 two frogs (Crinia?) which lay their eggs away from water; also a 

 number of tadpoles hatched from eggs laid away from water. 

 Some of the eggs were merely kept moist, and the tadpoles 

 emerged in about forty-eight hours, but from a number of the eggs 

 which were dropped into an aquarium on ist June last the 

 tadpoles did not emerge till 29th July and later. Why should 

 there be so great a difference between the hatching in air and in 

 water?— H. W. Wil.son. 



Entomological. — The valuable collection of Australian 

 Coleoptera formed by Mr. C. French, F.L.S., Government 

 Entomologist, as the result of many years' study, and which 

 contains a number of type specimens, has been purchased for the 

 National Museum, Melbourne. With this addition the Museum 

 will now* possess the most complete series of Australian beetles in 

 the world.
