interesting remarks illustrative of the affinities and analogies that connect 

 together many of the lesser groups ; and nearly the whole of his ornithologi- 

 cal papers contain at least incidental notices, which partially exhibit the 

 results of his attentive consideration of the subject even in its details. 



In the Annulosa Javanica, Mr. MacLeay proposed to apply, on a more 

 extended scale, to the investigation and arrangement of Insects, the prin- 

 ciples which he had previously advanced. He selected for this purpose 

 the collection formed in Java by Dr. Horsfield, but proceeded with them 

 no further than the first grand division of the Coleoptera, to which, from 

 the resemblance of their ha-va to the Chilopoda, he gave the name of 

 Chilopodomorpha. Beyond this he was prevented by unforeseen cir- 

 cumstances from pursuing his task, the completion of which, in the 

 masterly style in which it had commenced, was most sincerely to be 

 wished for. Removed, however, from the objects to which he was then 

 devoting his attention, others equally worthy of his determined study must 

 daily be presenting themselves to his active mind, and be continually 

 suggesting to him the possibility of adding to our stock of knowledge, by 

 giving to us, ere long, even though in a different form, that Prodromus, 

 as it were, of his views, as referring to the lesser groups, and even to spe- 

 cies, which we had been led to anticipate from his Annulosa Javanica. 



Another labourer has now presented himself in this ample field. In 

 the work which we have at present to analyse. Dr. Horsfield has under- 

 taken to investigate the Lepidoptera of Java on the same principles which 

 were found by Mr. MacLeay to apply to the Coleoptera of that island. 

 In the Introduction, which occupies the greater portion of the part now 

 before us. Dr. Horsfield alludes, with mingled feelings of personal regret 

 and fi-iendly satisfaction, to the events which interfered with the completion, 

 by the original authour, of the work of which this, although devoted to 

 another order of insects, may be regarded as a continuation. He adverts 

 also, with more detail than had previously been given, to the circum- 

 stances under which his Javanese collection, now in the Museum of the East 

 India Company, was commenced and completed, dwelling particularly 

 on the industry with which the larvce of lepidopterous insects were pro- 

 cured on all possible occasions, and on the care with which they were 

 watched, through their successive changes, until they assumed the form of 

 chrysaHs and finally became perfect insects. As the value of his work, so
