62 Address. [Feb. 



not been found possible to do much hitherto in communicating the results 

 of the collections that have been from time to time made. I am glad to be 

 able to state that the cataloguing of our Indian fauna has at length been 

 systematically commenced. Mr. W. Sclater has taken up the continua- 

 tion of the ' Catalogue of the Mammalia,' so well begun by Dr. Anderson : 

 Colonel C. Swinhoe and Mr. E. Cotes have published the second part of 

 their ' Catalogue of Indian Moths ' for the Trustees, and Mr. Wood- 

 Mason has in hand a ' Catalogue of the Mantoidea ' of which we have 

 an excellent collection. The first plate of Mr. W. L. Distant's ' Mono- 

 graph of the Oriental Cicadidce ' is ready, so that we may expect an 

 instalment of the work during the current year. Last year I announced 

 the commencement of the publication by the LinnaBan Society of the 

 results of the examination of the collections made for the Indian Museum 

 in the Mergui archipelago named through or by Dr. J. Anderson. A 

 special volume has been devoted to these memoirs, and the following 

 have appeared during the year : — Marine Sponges, by Mr. H. S. Carter : 

 Ophiuridce and on some parts of Ophiothrix variabilis, Dune, and 

 Oj^hiocampsis pellicula, Dune, by Professor P. Martin Duncan : Polyzoa 

 and Hydroida by the Rev. T. Hincks : a new species of Brachyonychus 

 by Mr. H. W. Bates : the Birds, by Dr. J. Anderson : on Bichelopsis 

 pellucida, Darwin, from the scales of an Hydrophid obtained at Mergui, 

 by Dr. P. P. C. Hoek, and the Podophthalmous Crustacea by Dr. J. G. 

 deMan. Most of these collections have already been returned, and all 

 will eventually find a place in the Museum. 



Nor has the practical side of zoology been forgotten. Collections of 

 the silk-producing moths have been made for distribution to the several 

 Provinces, and aid has been given to the inquiries now being made 

 into the diseases affecting silk- worms. The laboratory has been com- 

 pleted, and stocked with appliances for the prosecution of these studies. 

 To Mr. E. Cotes has been assigned the task of surveying the insect-pests 

 of India, regarding which we are practically in utter ignorance, but this 

 work can only be successfully accomplished by the co-operation of 

 intelligent observers throughout the country, and I need only mention 

 the subject to ensure your sympathy and support. An effort is also 

 being made to re-arrange in a practical way the great mass of ' Economic 

 Products ' that has come into the possession of the Museum from the late 

 Economic Museum and the Calcutta Exhibition. The object is to arrange 

 the specimens so as to make them a practical commentary on Dr. Watt's 

 ' Dictionary of Economic Products ', now being prepared by him for the 

 Government of India. This will contain the history, so far as known, 

 of each specimen exhibited, and hereafter it is intended to add to this by 

 a purely commercial survey of these products, showing the place where
