70. F-arviv of Hi/pat/miid Unca/iuii, (de Yillcrs) (Path. 

 Hist, 851), from the subcutaneous tissue of the face of a lx>y, 

 aged three years, at Glasgow, Montana, a case of l)rs. Hoyt 

 ami Getty. The child had had a series of swellings located 

 ll|X)ii the face, thigh, and other parts of the Ixxly, dating hack 

 to Octolx'r, 1<X).">; these attaining the size of half of a small 

 apple, each with the ap|>caraiice at the a]>ex of a small, 

 hluish lieinorrhagic point. After the appearance of this 

 apical spot the swellings would diminish and disapjx'ar, to be 

 succeeded by similar lesions elsewhere. Finally, in February, 

 1906, one developed on the face, in which, after it had been 

 well poulticed, the dark spot broke and the single grub 

 appeared, which was submitted for 'identification. The 

 writer has on one other occasion met a similar occurrence of 

 the larva of this fly in man, in a case of Dr. Herff, of San 

 Antonio, Texas (Med. News, December 6, 1902). In neither 

 of these cases was the grub in the last moult. 



Here, too, should be listed examples (Path. Mus., 13) of 

 the so-called Hypoderma ovis larva 1 , collected by Dr. J. J. 

 Repp from the subcutaneous tissue of a sheep, Ovis aries, 

 in Iowa. The grubs met in sheep beneath the skin are gen- 

 erally held to l>e larva 1 of H. lineatum rather than those of a 

 separate species, as has often been supposed. These are 

 considerably larger than the human specimens just men- 

 tioned, and probably represent a more advanced moult than 

 the above. 



71. Larvw of Cuter ebrafontinella, Clark (Path. Hist., 1798), 

 obtained by Dr. R. C. Rosenberger from the subcutaneous 

 tissue of the neck of a common cotton-tail rabbit, Lepus 

 sylvaiicus, killed in the vicinity of this city. 



72. Larvae of Gastrophilus equi, (Clark) (Path, Mus., 12), 

 obtained by Dr. J. J. Repp, in Iowa, from the gastric mucous 

 membrane of a horse, Equus caballus. 



73. Clothilla inquilfna (Path. Hist., 1064). These insects 

 were sent through the Pennsylvania State Health Depart-
