Show 802 LIEUT.-COL. H . H . G O D W I N - A U S T E N O N [June 21, indebted to him for the fine collection he has succeeded in bringing together in a few weeks. Having collected myself in the East, I know he must have worked hard and well to do it, pressed as he was lor time, and that time primarily occupied with his own particular branch of science, botany. When we consider also the birds, reptiles, and insects &c. which he brought home, it is seen how very valuable the results have been, considering the small outlay of money. Far greater are they, and far more valuable, than those of many better known and more costly expeditions, subscribed for and sent out by scientific societies from this country. Genus BULIMINUS.
