remains at Stockholm. Fabricius, the pupil of Linne, and his 

 worth}' successor in entomology, was much in England, and 

 described the insects in the collections of Sir Joseph Banks, 

 Dr. Hunter, and others ; and though some of these types are 

 missing, a large proportion are still preserved in the British Museum 

 (Natural History) and also in Glasgow. 



Oxford University Museum contains no types of the last century ; 

 but the nucleus of its entomological collection consists of the 

 united collections of Hope and Westwood, to which large additions 

 have been made from other sources, especially from the collection 

 of Wilson Saunders, which was specially rich iu the types of 

 moths described by Francis Walker from the collections formed 

 by Dr. A. B. Wallace in the Malay Archipelago. As Walker's 

 descriptions are frequently short and unsatisfactory, it was a matter 

 of considerable scientific importance to verify them as far as possible 

 from the original types ; and hence the present work was under- 

 taken by Col. Swinhoe, and the first volume, containing Sphinges 

 and Bombyces, and illustrated by eight plates, was published iu 

 1892. The second volume, just issued, and twice the thickness of 

 the first, completes the subject. It is a full synonymic catalogue 

 of the Eastern and Australian moths in the Oxford Museum, and 

 special attention has been paid to the elucidation of Walker's types, 

 a considerable number of which are figured, as well as many new 

 species which are now described and figured by Col. Swinhoe and 

 his coadjutors for the first time. 



Books like the present are of great use to all entomologists 

 who are working at exotic moths, and we cordially recommend 

 Col. Swinhoe's work to their special attention. 



Sexual Dimorphism in the Animal Kingdom. By J. T. Cunningham, 

 M.A. London : Adam and Charles Black, 1900. 



Colour in Nature. By Marion I. Newbigin. London : John 



Murray, 1898. 

 In the production of the first-mentioned book, the nucleus of which 

 appeared in the pages of the now unhappily extinct ' Natural 

 Science,' Mr. Cunningham has, without doubt, spared neither time 

 nor pains. As a result, he has brought together a considerable 

 number of facts of real and lasting value. Whether, however, his 

 interpretation of these facts will find favour with students of this 

 subject is another matter : we shall be surprised if he succeeds in 

 making a single convert. 



Mr. Cunningham is Lamarckian in principles. His object has 

 been, he tells us, not to " attempt to prove that acquired characters 

 are inherited," but " merely to point out how remarkably the multi- 

 tudinous facts all agree with the hypothesis that secondary sexual 

 characters are due to the inheritance of acquired characters.'' This 

 very cautious statement of his case looks somewhat as though 

 Mr. Cunningham were a little afraid of the ghost which he has 

 conjured up. 



The beard of man, and especially of the Caucasian races, it is 

 suggested, owes its conspicuous development to the stimulation of
