similar situations. Of the larvfe of Diptera, those of Musca and 

 CEstrus seem to be most common ; those of Musca forming by 

 far the largest number of any one genus, thirty-seven cases hav- 

 ing been tabulated and reported by Mr. F. W. Hope, in the 

 Transactions of the Entomological Society of London, Vol. II. 

 The species of these maggots was generally unknown ; but many 

 were recognized as belonging to M. vomitoria., M. carnaria, and 

 M. domestica. 



The genus Oestrus seems to be that which most frequendy 

 deposits upon the extei'nal surfjice of the human body. Of these 

 cases he had met with Ivvo upon the scrotum, two in the skin of 

 the abdomen, two in the scalp, and one in each of the following 

 named situations, — leg, arm, scapula, ear, jaws, antrum, and 

 stomach. These larvae were either called Oestrus hominis, or 

 they were described without a specific name, with the exception 

 of one, which was CEstrus bovis. 



A full account of this case was read before the Boston 

 Society for Medical Improvement, and published in the 

 Boston Medical and Surgical Journal of October 8, 1857. 



Mr. C. J. Sprague exhibited specimens of a new fun- 

 gus, Glcsosporium crocosporum, Berk, and Curt, named 

 from specimens collected by himself. 



This fungus is found very commonly in autumn upon various 

 kinds of melon. It appears in orange spots upon the outer sur- 

 face, and is generally found in places which seem to have re- 

 ceived a blow. Sometimes, however, the fungus covers the 

 whole fruit in a yellow and orange incrustation. It belongs to 

 that numerous family of fungi which infest the leaves and bark 

 of all plants, and the epidermis of fruits. There is no true peri- 

 thecium, but the spores spring in myriads from a nucleus just 

 beneath the epidermis, and then ooze forth through an aperture 

 in irregular granular masses drying on the surface. They are 

 elongated oval in shape, and of a clear yellow-orange color in 

 mass. 



Mr. Sprague also exhibited the spores under a microscope.
