wild silk-worms which are indigenous to India. Besides the Bombyx mori, the Doctor enumerates the following seven species, formerly unknown:—1. "The wild silk-worm of the central provinces, a moth not larger than the Bombyx mori." 2. "The Joree silk-worm of Assam, Bombyx religiosæ, which spins a cocoon of a fine filament, with much lustre. It lives upon the pipul tree (Ficus religiosa), which abounds in India, and ought therefore to be turned to account in breeding this valuable moth." 3. "Saturnia silhetica, which inhabits the cassia mountains in Silhet and Dacca, where its large cocoons are spun into silk." 4. "A still larger Saturnia, one of the greatest moths in existence, measuring ten inches from the one end of the wing to the other[1]; observed by Mr. Grant, in Chirra punjee". 5. "Saturnia paphia, or the Tusseh silk-worm, is the most common of the native species, and furnishes the cloth usually worn by Europeans in India. It has not hitherto been domesticated, but millions of its cocoons are annually collected in the jungles, and brought to the silk factories near Calcutta and Bhagelpur. It feeds most commonly on the hair-tree (Zizyphus jujuba), but it prefers the Terminalia alata, or Assam tree, and the Bombax heptaphyllum. It is called Koutkuri mooga, in Assam." 6. "Another Saturnia, from the neighborhood of Comercolly." 7. "Saturnia assamensis, with a cocoon of a yellow-brown color, different from all others, called mooga, in Assam; which, although it can be reared in houses, thrives best in the open air upon trees, of which seven different kinds afford it food. The Mazankoory mooga, which feeds on the Adakoory tree, produces a fine silk, which is nearly white, and fetches 50 per cent. more than the fawn colored. The trees of the first year's growth produce by far the most valuable cocoons. The mooga which inhabits the soom-tree, is found principally in the forests of the plains, and in the villages. The tree grows to a large size, and yields three crops of leaves in the year. The silk is of a light fawn color, and ranks next in value to the Mazankoory. There are generally five breeds of mooga worms in the year; 1. In January and
