extensive benefits which must accrue to the science when it 

 shall be carried into effect. 



Such then being the present state and such the future pro- 

 spects of this science, it is with much satisfaction that we have 

 again to review the labours of a naturalist, who is an active 

 contributor in all the undertakings to which we have alluded; 

 and who, combining with some of the new views of zoological 

 philosophy his own acumen and minute accuracy, and com- 

 prehensive acquaintance with the habits and natural relations 

 of the subjects of his researches, derived from contemplating 

 them in their native clime, has produced a work of commen- 

 surate excellence in all respects. 



The first five numbers of Dr. Horsfield's zoological Re- 

 searches have already been noticed in the Philosophical Maga- 

 zine*; but in reviewing the contents of those now before us, 

 which complete the work, we must recur to two or three sub- 

 jects described in them, for the purposes of adverting to the first 

 application of the distinction between affinity and analogy to the 

 discrimination and distribution of the Mammalia, and noticing 

 the author's recent establishment of a new and interesting 

 subgenus of Ursus, of which the U, malayanus, described in 

 the fourth number of these Researches, forms a species. 



The graphical illustrations of the present numbers, con- 

 sisting of twenty-four coloured plates of as many animals, and 

 three engravings of anatomical details, are of similar excellence 

 to those in the previous numbers, and have been executed 

 by the same artists, — Messrs. W. Daniell, W. Taylor, and A. 

 Pelletier. 



In the enumeration of the mammiferous animals described, 

 we shall adopt the order proposed by Dr. Horsfield for their 

 arrangement in the volume, which is nearly that of Cuvier. 

 The first we have to notice is Semnojnthecus Pyrrhus, thus 

 characterized : — S. rufus nitore splendide-fulvo, pectore abdo- 

 mine artubus intrinsecus caudasque basi subtus pallide-flavis. 

 — Lutung of the Javanese. 



This species agrees with the 8. mauriis, described in a pre- 

 ceding number of the work, in all points except the exteinal 

 covering ; the permanency of the difference in which, and the 

 peculiar name of the animal among the natives of .Java, appear 

 chiefly to have determined the author to regard it as a dis- 

 tinct species. • In the S. maurus the fur is intensely black ; in 

 the present animal it is reddish-brown, with a beautiful golden 

 gloss on the back, head, tail, and extremities. 



The Vcspcrtilionid(e figured and minutely described amount 

 to four in number, besiiles many others of which specific cha-
